Two adjacent bird flu polymorphisms are emerging on the pandemic H1N1 NA segment primarily within 2010 human sequences that carry the HA 188T. This two change combination is found in PF11 on 17 Neuraminidase sequences, but more than 200 times in Avian H3N8, Avian H1N1 and every Avian HxN1 serotype from H2N1 to H12N1. The UKWhiteChapel4880374_2M_2010_11_28 carries these two adjacent NA changes.

Single Genetic Variance May Elicit Substantial Viral Behaviour Changes

Single Genetic Variance May Elicit Substantial Viral Behaviour Changes

ironorehopper said:
Although travel-log of the above mentioned gene polymorphisms is very useful to track evolution and to understand influenza viruses ecology and the development of distinct lineages, the actual impact on field epidemiology remains to be established.

In other words, we have to wait at least for two or three week, when the epidemic peak should be reached and a first, retrospective analysis of transmissibility and intrinsic virulence of H1N1 (2009) strains are circulating in UK and elsewhere will be more clear.

Human immune system can fight influenza probably even with immune memory and not only through the main humoral response, elicited by vaccines.

Common-sense hygiene measures, such as handwashing, cough etiquette, and avoid crowded places, as well as remaining at home when ill or feverish represent also very useful instrument to reduce or slow the speed of propagation of the virus into community.

Hindsight is practically more accurate than foresight. We all may agree on that fact.

Once an event has passed, the deeper measurements that were taken during the event may be closely evaluated. Given that consideration, proposals should be in hand now across the UK. Field epidemiology, in this present matter, may be justified in increasing assets to the present cases so that these questions may be answered very soon . . . prior to a more distinct or more severe wave.

In most cases of genetic variation, the clinical variation may only be known by closely tracking, correlating and culling the data points. In the UK today, severe disease is a fact, at a higher concentration than has been seen (another fact), whilst the overall case count remains low. Those general cumulative statistics guide us to a more detailed investigation which must occur at the individual case level. In order for those investigations of the actionable data to occur, the importance data points must be captured at the time of the event.

When the count of ICU beds for ILI has risen from 100 to 302 over less than two weeks, clearly additional and improved surveillance is indicated.

Ergo, very few genetic changes may be conclusively deemed as creating a generalised "severe" outcome.

On the other hand, if the data is not gathered at the time of the event, neither the scientists, nor the public will ever discern the potential connections. Blind is blind, but closing one's eyes at the critical time immediately prior to any crisis is an intentional decision. Those types of decisions are predictable as to outcome: preparation time and quality is reduced.

Let's continue to closely investigate and postulate each iota of information available, while encouraging more robust systems and deeper participation.

The NA polymorphisms discussed here are highly correlated to the HA 188T that has recently begun spreading (rare yet) across the world. If that HA 188T is under inspection, perhaps we all should increase focus to this associated NA pair of changes at aa240 and aa241.

This NA question is raised alongside the more distinct potential of a significant change in the RBS range from 225 to 230.

What we do know is that present and historical data perfectly demonstrate that very slight changes in genetics, as few as one genetic change, may create much higher levels of severity.

Is this change one of those types of variations? No risk at all exists in evaluating the potential. Significant risk is created when emerging data is tabled for "future study" during a crisis.

Working with the current sparse data allows very few comprehensive and exacting responses; however, based on simple frequency analysis, a very slight potential also exists in the UK for HA changes upstream and adjacent to aa225, at residues 223 or 224.

At this juncture, "Low Reactors" are recorded with 224 amino acid variation on backgrounds with additional changes, but the single change has not been evaluated alone on a pH1N1 background for Vaccine Escape as far as we've seen. Validation on this matter would be appreciated.

223E was only recently documented in the PF11 reservoir from the early pandemic last year from the Southern Hemisphere in Brisbane. As the White Chapel sequence, UKWhiteChapel4880374_2M_2010_11_28, taken from the 2 year old boy prior to the severe UK wave is closely related to an August 2010 Brisbane sequence as discussed, we all must be on watch for changes beyond the most likely aa225.

Will the severity in the UK be caused by a single change or a complex of variation?

No one will know until properly managed sequences are available in quantity with clinical metadata.

UK and Brisbane Similarity

UK and Brisbane Similarity

The HPA released a set of 4 UK sequences at GISAID on 2010-12-20 from the pre-severity phase dating from 2010-08-07 to 2010-11-28. We provide our ongoing and quite skeletal notes from the focal analysis for the sake of timeliness in collaboration. Additional interpretation will be pursued at the weekend and updated here at FT.

No imagination is required to see that 225G and / or 156E may be eventually, if not currently, attracted to the UKWhiteChapel4880374_2M_2010_11_28 background due to extensive homology shared with the previously discussed OzBrisbane209_51F_2010_08_09.

Brisbane and UK Reservoir Sharing

Brisbane and UK Reservoir Sharing

Are we cross-validating the fact that Brisbane, a potential donor into the UK severe wave, and all of Queensland are, at this moment, experiencing a 700% increase in case count for 2010 influenza over the December 2009 cases?

Is it possible that the colder weather in the UK is creating aberrant host-pathogen behaviour or inducing genetic variation in-vivo that creates a more severe outcome though the overall case count remains low in the UK? Would the warmer weather of the Southern Hemisphere perhaps allow a higher transmissibility with less severe outcomes from the same initial infectious dosage of the same viral particles?

Apparently, we may have been presented with the ideal experimental model to determine the effect of atmospheric measures against clinical outcomes and genetic acquisition (speed and quality) if we find that the UK and Australia are concurrently suffering under the same viral genetics reservoir.

The release of sequences with clinical metadata from the UK fatalities alongside sequences from December in Australia would prove useful in these evaluations.

Australia to Japan to UK to Iran

Australia to Japan to UK to Iran

The latest sequences soon to be on file at GenBank demonstrate ongoing transmission of pandemic H1N1 influenza carrying HA 188T. The Tehran University of Medical Sciences has made available A/Karaj/5327/2010(H1N1), sampled on 2010-12-06.

The National Institute for Infectious Disease in Japan introduced 13 sequences at GISAID today. One from October 2010 appears to be an intermediate form in this emerging background with 188T, though the sequence is truncated at a critical point.

Notice as we've mentioned in previous posts that the most recent IranKaraj sequence seems to have become more refined through simplification, perhaps culling the unnecessary changes (duplicate function / human species maladaption?) from JapanKanagawa74 (122I, 143R & 186P) while maintaining the useful foundation (syn34N, 146G, 188T & 200T) and extending recombination such as the syn465N found in Brisbane in August 2010, missing in the UK, then reapplied onto the IranKaraj sequence.

In similar fashion to IranKaraj at syn538F, recall that 3 of 4 sequences from the latest UK deposit carry polymorphisms in the HA gene segment downstream of aa499, including 504G, 513V, syn529L and 537G.

The PF11 viral reservoir appears to be introducing diversity with new genetic material at the head and the foot of the HA gene segment. Many of the recent related sequences to the UK backgrounds (at individual point variations) happen to carry polymorphisms in this post-aa499 area of the HA gene segment, including OzVictoria670_2010_11_14 (syn512R), OzSydney217_2010_09_19 (523A), Stockholm5_2010_08_27 (525G), GhanaFS10_4259_2010_08_27 (syn537S), GhanaFS10_4241_2010_08_25 (syn537S), Florida13_2010_08_02 (512M), OzVictoria800_2010_07_02 (502K, syn529L [CTa]), India3725_2010_04_03 (syn526S), Ukraine123_2010_02_14_xL (syn500R), Netherlands2629_2009_12_04 (507E), RussiaPermCREI_ZTS_2009_11_30 (syn542S), Brunei218_2010 (syn538F) & BrasilBahia15525_42M_2009_09_05 (syn499N mix wt, 511I mix wt).

Early Pandemic 188T from Japan released this week

The Tohoku University Graduate School of Medicine in Sendai, Japan released a sequence dated only as 2009 (MDCK passage) that carries the 188T featuring on the sub-clade building recently in the UKWhiteChapel4880374_2M_2010_11_28 sequence.

The Sendai sequence is complete and demonstrates none of the trailing polymorphisms of the emergent strains found across Australia, England and Iran. Additional date specificity and host meta-data would clarify the positioning of this sequence in the genetic acquisition train.

HA 188T rapidly emerged geographically throughout 2010 and is now found in 26 pH1N1 Human and 1 pH1N1 swine sequences across Africa, Asia, India, Oceania, the UK, Brunei, Iran and the United States.

Data Transparency and Collaboration

Data Transparency and Collaboration

Collaboration requires data sharing, sometimes when the data is uncomfortably rough or even inexplicable. But that's the purpose of collaboration, right?

We collaborate to discover something that we did not already know. We collaborate when world health is in question.

UK_December_Emerging_Genetics_v0.xls

This GeneWurx Version Zero Excel spreadsheet represents an effort to externalise to the public our current rough lab notes on the 4 published UK HA gene segments and worldwide HA sequences that we've ascertained may be related. UK titles and UK polymorphisms are color-coded green wherever they are found.

Each column represents a sequence of interest. The rows are filled with change data ordered by the amino acid position. This presentation of detailed data obviously required some careful editing for brevity. Even so, the reviewer will be inclined to scroll and / or hide columns in order to fully review relationships.

The materials demonstrate the flow of genetic data from the Southern Hemisphere 2010 into the Northern Hemisphere today. For example, investigate the various similarities from columns AQ to AZ. The UKWhiteChapel4880374_2M_2010_11_28 sequence in column AX is our primary interest due to patterning suggestive of a capability to carry 156E / 158E and / or 225G.

The authors are grateful to GenBank and GISAID for making their depository of valuable genetic material accessible and to those from many countries who have shared their sequences for the sake of public health. We also are thankful to a certain physicist who initiated the concept and layout for public presentation of this detailed genetics data.

As always, any errors are those of the authoring team. Please provide errata via private message as you discover required corrections.

UK Potential 90% Increase of Influenza Cases to Total ICU Beds

UK Potential 90% Increase of Influenza Cases to Total ICU Beds

** Caveat **

Due to data scarcity, apparently sanctioned by officials, this evaluation is forced to extrapolate from media reports.

The factor used to fill the gap is defined clearly as to source and the calculations are presented via a reusable Excel spreadsheet.

** End Caveat **

Total case count officially increased by 44.9% in the UK, but ICU beds with Influenza (London) appear to have potentially risen by up to 90%.

Notice also that official releases early today failed to provide a new count on total or district Influenza ICU cases.

The December 23rd official report (latest) showed that 1 of 7 ICU beds (~13%) were Influenza cases. Compare that figure to the 2009 pH1N1 Pandemic peak of roughly less than 1 of 12. The Health Emergency campaign group today claimed that London hospitals are reporting that up to 25% of ICU beds are Influenza cases.

For the purposes of least optimal projections, recasting the factors countrywide is a reasonable evaluation due to the fact that London appeared to be trailing in cases and severity until this report. Based on the 25% number and 3500 beds nationwide, a practical doubling is indicated of the Influenza cases percentage of ICU / ITU over 5 to 6 days and brings the total cases at this time to potentially ~875 people in Intensive Care at one time for Influenza, a 90% increase in 5 to 6 days.

GeneWurx_UK_ICU_Categories_v0.xls

Again these factors are recast from London across the entire nation due to lack of data reporting and, as such, the results may be heavily skewed in either direction. Understanding the assumptions behind the calculation allows a guidepoint to be reached. If the results prove solid, then the case count rose by ~45% while the ICU percentage, at least in one major city (London), may have increased by 90% or more.

These extrapolations suggest a severe wave that is continuing.

GeneWurx and the concerned public would be more than pleased to have these calculations invalidated by actual official reports of current information from the public health officials, alongside genetic sequences tagged according to mild, severe and fatal cases with clinical progression meta-data.

2010-12-30 Epidemic Threshold Reached, 1 to 4 Year Old UK Age Bracket

2010-12-30 Epidemic Threshold Reached, 1 to 4 Year Old UK Age Bracket

Shiloh has opened a thread discussing the fact that an epidemic threshold has been reached officially in the UK for the age range of 1 to 4 years old, the very young children.

http://www.flutrackers.com/forum/showthread.php?t=157361

The epidemic threshold is also being approached for the entire under 5 year old group, but has not been reached due to the low count in the under 1 year old category. The obvious question of whether these low results in the baby age bracket are accurate or due to failure to diagnose is not satisfied at this time.

UK White Chapel Sequence Hybrid with animal H7N7 and Human Adapted Seasonal Polymorphisms

UK White Chapel Sequence Hybrid with animal H7N7 and Human Adapted Seasonal Polymorphisms

An inspection of the final syn529L polymorphism on the White Chapel sequence from the 2 year old boy, noted here and previously, demonstrates a change unique to pH1N1 even at this late stage.

Though 2 different additional versions (CCa, tTG) of this silent polymorphism at aa529 have been found in the reservoir in rare quantities, the change at the third base of the codon (CCt) for the White Chapel sequence appears to have propagated from an entirely separate origin, a human-adapted seasonal H1N1 strain circulating in 2007. With a total of 37 HA syn529L instances in human Pandemic H1N1 2009 on record for the earlier CCa and tTG codings, this novel change (CCt) may demonstrate new behaviour for this virus.

Consider that human-adapted changes from seasonal H1N1 2007 also share extensive homology with the NA for this White Chapel sequence.

Frequent change has been noted on emergent 2010 pH1N1 strains after amino acid position 500 and in some cases has been associated with fatality (502K and syn542S). In a domain briming with recent diversity, these 38 changes of three variant silent codings at a single position, aa529, offer a block of data that may interest keen investigators.

GeneWurx has prepared a rough estimation for public review in an Excel spreadsheet detailing the findings as of December 25, 2010 for syn529L as related to the current emerging epidemic in England, Wales and Scotland.

Novel UK White Chapel Neuraminidase Hybrid from animal H3N8 and Human Seasonal H1N1

Novel UK White Chapel Neuraminidase Hybrid from animal H3N8 and Human Seasonal H1N1

Neuraminidase (NA) Review

UKWhiteChapel4880374_2M_2010_11_28

Six of the seven polymorphisms on the Neuraminidase (NA) for UKWhiteChapel4880374_2M_2010_11_28 have now been confirmed with matches to various seasonal human H1N1 (S9, S8, S7). The seventh change, a T->C (T235C) SNP, coding for 79P, is found extensively in the zoonotic reservoirs across multiple species.

This first base donor for the UK PF11 NA 79P codon (cCA) occurs at least 19 times in H3N8 from 2009 to 2005, spanning a wide range of mammal species:

Horses
Dogs
Swine

Geographic significance is found in Sydney, Australia where the SNP is found in the following 2007 H3N8 animal sequences.

H3N8 canineSydney6692_2007_10_15
H3N8 canineSydney6525_2007_10_14
H3N8 equineSydney6085_2007_10_10

This fact becomes of higher interest when we inspect the similarity of the dates and sample identification numbers. The possibility exists that these 3 animals were in a transmission chain on a ranch that may have included undetected or unsequenced human infection.

Note that the HA of UKWhiteChapel4880374_2M_2010_11_28 is most closely matched to an Australian sequence. The three H3N8 sequences from Sydney also carry the HA syn474C found in a separate sub-clade within the 4 UK sequences on UKCambridge118_4F_2010_11_19. Evidently, pH1N1 is moving toward homology with non-human mammal H3N8 on the HA AND the NA gene segments in two separate genetic backgrounds within the UK.

Sub-segment genetic recombinations from H3N8 onto human backgrounds are considered of interest in relation to severity.

Furthermore, the SNP coding for the NA 79P is also demonstrated in two other zoonotic Influenza serotypes. In 2009, the change appears in Eastern Europe on an Avian H7N7 sample, mallardPolandM446_2009. Recall that the UKWhiteChapel4880374_2M_2010_11_28 HA 188T may have also originated from H7N7. Furthering the animal connection, the NA 79P SNP appears on a domestic poultry, lab-derived vaccine strain on the H9 background.

This NA 79P from the animal reservoirs may have accumulated onto a very human-adapted NA in Australia / UK, generating a novel gene segment with a combination previously unknown in humans.

UK Severe Influenza Cases in ICU Percentage Update

UK Severe Influenza Cases in ICU Percentage Update

** Please note that the figure of 738 ICU Influenza patients has been defined by RoRo as being only for England. Figures for Wales, Scotland and Ireland will be produced as they are available. **

Total case count officially increased by 44.9% in the UK, but ICU beds with Influenza (HPA Week 52) appear to have risen at the substantially higher rate of 60%.

The December 23rd official report (latest) showed that 1 of 7 ICU beds (~13%) were Influenza cases. Compare that figure to the 2009 pH1N1 Pandemic peak of roughly less than 1 of 12. The 738 ICU cases reported today demonstrate that UK hospitals are utilising 1 of 5 ICU beds for Severe Influenza cases.

GeneWurx_UK_ICU_Categories_v1.xls

These extrapolations suggest a severe wave that is continuing.

GeneWurx and the concerned public would like like to thank the officials who released the data today. Additional information is, however, required, including more frequent updates on cases, ICU cases and fatalities, alongside genetic sequences tagged according to mild, severe and fatal cases with clinical progression meta-data.

HA 230I Cross-Linked in Slovakia on Broad Background

HA 230I Cross-Linked in Slovakia on Broad Background

We may find this set of sequences to be instructive to the UK severe wave in the days to come when NIMR releases sequences.

HA 230I Cross-Linked in Slovakia on Broad Background

Last Updated 2010-12-31

The UK National Institute for Medical Research published a group of sequences on 2010-12-30 at GISAID. One group originated from the National Public Health Institute of Slovakia.

An unusual and persistent background pivoting around 8 polymorphisms on 5 sequences arose during March 2010 in Slovakia pairing two silent polymorphisms for the first time (syn23L and syn177L (CTt)). The Slovakian sequences are all cross-linked with the HA syn413K and the NA syn407V.

Of particular interest is the Slovakia1625_56X_2010_03_30_xL from a 56 year old of unspecified gender due to the 9th polymorphism, a very rare HA 230I. As of this deposit, the multiple backgrounds that are permissive to the HA 230I change extends to a new platform that appears to transmit (5 geographically similar sequences in 5 days).

GeneWurx has prepared an Excel spreadsheet investigating potential genetic acquisition in the currently uncharted severe Pandemic H1N1 wave in the UK. In Version 1 of this spreadsheet, the Slovakian 230I sequence takes Column U and provides homology to one UK White Chapel sequence of interest.

UK Rise in Neuraminidase Inhibitor Anti-Viral Drug Resistance

UK Rise in Neuraminidase Inhibitor Anti-Viral Drug Resistance

UK Rise in Neuraminidase Inhibitor Anti-Viral Drug Resistance

The UK HPA Weekly National Influenza Reports covering the emerging epidemic from the past two weeks (Week 51 and Week 52) provide insight into data scarcity surrounding anti-viral drug resistance.

Oseltamivir-resistance may be determined genetically from a Single Nucleotide Polymorphism (SNP) H275Y on the Neuraminidase. Clinical anti-viral resistance and / or ineffectiveness in Pandemic H1N1 Influenza continues to manifest much more widely than can be attributed to the genetic variance of NA 275Y. In the future, other factors may be identified as genetically leading to the clinical manifestations in cases that do not demonstrate H275Y, but for the moment, the measurement is at that single change.

The HPA Week 51 data reported 3 TmX cases from 402 tested (~0.75%).
The HPA Week 52 data reported 5 TmX cases from 336 tested (~1.49%).

As you can see, the percentage of resistant cases week over week increased by 99%. Unfortunately, data sparsity alongside the fact of taking percentages of percentages may not allow this figure to be fully reliable for decision-making.

On the other hand, in a crisis when faced with limited testing capacity and limited testing foundation, these are the types of acceleration / deceleration calculations that must be made. Data that is available is used. GeneWurx would like to see clinical meta-data paired with genetic sequences to assist in pinpointing various HA polymorphisms that may also be associated with drug resistance, such as those trailing HA aa500.

GeneWurx has prepared an Excel spreadsheet so that the public may track any ongoing official and / or unofficial data concerning Anti-Viral resistance patterns.

GeneWurx_UK_2010_2011_Severe_Wave_TmX_v0.xls

Bear in mind that a recent seasonal influenza rapidly progressed from Anti-Viral sensitivity to Anti-Viral resistance across the world in less than one full season when the percentage of strains demonstrating NA H275Y reached approximately 2%.

More than 100 drug-resistant human Pandemic H1N1 sequences are on file considering just North America and Asia. Washington01_2010_04_02_TmX from the United States registered with 33 polymorphisms across the HA and NA gene segments. In August 2010, GeneWurx evaluated 7 sequences from Japan with extensive HA diversity and H275Y TamiFlu Resistance.

With drug resistant, hypermorphic strains carrying shared HA polymorphisms now being documented across a wide geography, will the resistant 2% begin to spread in Winter 2010-2011?

HA 158E in Cameroon Pair with Additional HA Changes Correlated to Anti-Viral Resistance

HA 158E in Cameroon Pair with Additional HA Changes Correlated to Anti-Viral Resistance

HA 158E in Cameroon Pair with Additional HA Changes Correlated to Anti-Viral Resistance

The UK National Institute for Medical Research published a group of sequences on 2010-12-30 at GISAID. One group originated from the Centre Pasteur du Cameroun.

HA 158E, a polymorphism associated with Vaccine Escape, appears in two Cameroon sequences upon a highly plastic background that is demonstrated worldwide, including multiple non-adjacent, coastal areas of the United States and in Australia on a background that may be permissive to HA 230I.

This Cameroon background has additionally been conserved in domestic poultry Pandemic H1N1 from Canada.

The most recent sequence taken in April 2010, Cameroon10v_1090_2010_04_08, also carries HA syn223V just upstream of the 225 amino acid position that is so often tracked. HA syn223V has been co-located with 454N in Texas45131774_2009_09_13. 454N and other changes at 454 are highly correlated to the most recent UK sequences on file and to a chain of sequences spanning Australia before the UK and Iran after the UKWhiteChapel4880374_2M_2010_11_28 <a href="http://www.flutrackers.com/forum/showpost.php?p=384242&postcount=139" target="_blank">sample</a>. The related hypermorphic Australian sequence, OzVictoria508_9F_2010_07_24, shares <a href="http://pf11.blogspot.com/2010/09/australia-shows-novel-ha-238d-in-august.html" target="_blank">8 changes </a>with Cameroon.

Notice that the syn254P is has been found on a Japanese TamiFlu Resistant sequence. 523A, which is found at various points on Vaccine Escape and TamiFlu Resistant sequences, is also contained within the potential UK donation reservoir from Australia.

Based on these updates from NIMR, potential exists for a 158E emergence in the UK.

GeneWurx has prepared an <a href="http://genewurx.com/data/GeneWurx_UK_December_Emerging_Genetics_v2.xls" target="_blank">Excel spreadsheet</a> investigating potential genetic acquisition in the currently <a href="http://www.flutrackers.com/forum/showthread.php?t=156569" target="_blank">uncharted severe</a> Pandemic H1N1 wave in the UK. In Version 2 of this spreadsheet, the Cameroon 158E sequence takes Column W and provides homology with potential predecessors to one UK White Chapel <a href="http://www.flutrackers.com/forum/showpost.php?p=384072&postcount=119" target="_blank">sequence</a> of interest.

UK Homology on Cameroon Pair Carrying 230I Permissive SNPs

UK Homology on Cameroon Pair Carrying 230I Permissive SNPs

UK Homology on Cameroon Pair Carrying 230I Permissive SNPs

The UK National Institute for Medical Research published a group of sequences on 2010-12-30 at GISAID. One group originated from the Centre Pasteur du Cameroun.

Two young boys, ages 10 and 7, are part of a transmission chain extended over 13 days. Cameroon10v_00812_7M_2010_03_23 is an exact HA match with Cameroon10v_00751_10M_2010_03_10.

These two sequences carry genetics common to the most recent October and November 2010 UK sequences while combining polymorphisms associated with RBD changes including 230I. Using domaining produces a clear relationship between Cameroon and the 230I carrier and 230I permissive sequences. Simple scrolling of the provided spreadsheet demonstrates the relationships.

GeneWurx has prepared an <a href="http://genewurx.com/data/GeneWurx_UK_December_Emerging_Genetics_v3.xls" target="_blank">Excel spreadsheet</a> investigating potential genetic acquisition in the currently <a href="http://www.flutrackers.com/forum/showthread.php?t=156569" target="_blank">uncharted severe</a> Pandemic H1N1 wave in the UK. In Version 3 of this spreadsheet, this Cameroon representative sequence, Cameroon10v_00812_7M_2010_03_23, takes Column U and provides homology with UK <a href="http://www.flutrackers.com/forum/showpost.php?p=384072&postcount=119" target="_blank">sequences</a> of recent interest.

Cameroon 230I Permissive Sequences Carry H3N8 and H7N7 Zoonotic Matches

Cameroon 230I Permissive Sequences Carry H3N8 and H7N7 Zoonotic Matches

Cameroon 230I Permissive Sequences Carry H3N8 and H7N7 Zoonotic Matches

Recently published sequences from Cameroon show homology to backgrounds that have supported HA 230I. Several of these backgrounds carry homology to animal reservoirs and Cameroon follows suit. These two young boys, ages 10 and 7, who were part of a transmission chain extended over 13 days may or may not have had close contact with animals. Cameroon10v_00812_7M_2010_03_23 is an exact HA match with Cameroon10v_00751_10M_2010_03_10.

The sequences are potentially related to the severe wave in the UK that has filled hospitals and, more importantly, Intensive Care Units to capacity (edit S.S.). English elective surgeries are actively being cancelled. Families are being told not to attempt a hospital visit in the case of Influenza due to the infrastructure strain. Emergency departments are forced to place patients on gurneys due to no beds being available while operating theatres and lounges are being hastily converted to patient rooms. These and other escalation procedures are reported in the media to be underway in hospitals throughout the country with several institutions presently indicating "Red" or "Black" alert levels.

Animal influences on the genetics of human-infecting Influenza like the pH1N1 strain may generate extreme outcomes and variant clinical behaviour. In these cases from Cameroon, the syn350G, 457R, syn461K and syn466G, among others, share homology with animal reservoirs as noted on the sequence details. We have discussed widely the HA 188T found in the emerging sub-clade including Australia, the UK and Iran. HA 188T is also found in the H7N7 reservoir, as is the syn350G on these Cameroon sequences.

The 457R and syn466G appear together within the H3N8 reservoir and are paired on a particularly interesting set of related horse and dog sequences from Australia. These two changes fall into a domain band that is related to the emerging sub-clade from Australia to the UK.

UK Sequences from 2009 Document Transmission of TamiFlu Resistance

2011-01-06

The UK Health Protection Agency released a set of 38 English sequences on 2010-01-04 at GenBank, but not from the current 2010 severe wave. These 38 HA and NA publications are delayed more than one year, covering September 10 to November 25, 2009. No sequences are included from the pandemic wave currently circulating.

65% of the English sequences are cross-linked with HA syn413K and NA syn407V. 225E occurs in 5 sequences and 225G in 2 sequences. Person to person transmission of oseltamivir-resistance via NA H275Y is noted within a hematology unit that encompasses 15 of these 38 sequences. All but one of the anti-viral resistant sequences are on a cross-linked background. One simple drug resistant sequence carries 225G on the cross-linked background.

The drug-resistant 15 are unremarkable, but for their simplicity. The 225G sequences and a representative sample of the anti-viral resistant sequences is presented after the complete listing of TmX sequence names sorted by date.
