Re: Russian Scientists Prove Mosquitoes, Bats Are Avian Influenza Vectors

I would like to see more data on the Sverdlovsk Oblast regional office of the Federal Service for Surveillance in the Area of Protection of Consumer Rights and Human Welfare....

Rospotrebnadzor -- or the "Federal Service for Surveillance in the Area of Protection of consumer Rights and Human Welfare" -- is the Russian Agency for Health and Consumer Rights [Рос потреб надзор = Ros Potreb Nadzor = Russian customer oversight].

I imagine it as a sort-of FDA of Russia -- it seems to be connected in some way to (a subordinate unit of?) the Ministry of Health:

Google-translated from Russian:

Federal Service for Surveillance in Consumer Rights Protection and Human Welfare Russia (former fire), the federal service falls Ministry of Health and Social Development of Russia.

Here's the main Rospotrebnadzor website [Russian only from what I can see]:

http://www.rospotrebnadzor.ru/

Sverdlosk Oblast is in the Ural mountains here:

http://en.wikipedia.org/wiki/Sverdlovsk_Oblast

So, I guess this report comes from somebody working for the Sverdlosk regional office of the Rospotrebnadzor.

Haven't found the original report yet, but I'll keep looking.

BTW - the Rospotrebnadzor basic info on H5N1 page is here (nothing new to anyone here)...

...and they've also got the latest WHO bf casualty chart up here:

Re: Russian Scientists Prove Mosquitoes, Bats Are Avian Influenza Vectors

Another paper carried the story as well. Babelfish translates "Комары" as gnats rather than mosquitoes ... but Wikipedia in Russian show mosquitoes for the word:

http://ru.wikipedia.org/wiki/Комар

babelfished from Russian:

Gnats can transfer the viruses of influenza
Russian virusologists convincingly it is shown the ability of gnats to transfer the viruses of the influenza of group A.
Oct 10, 2006

To it it relates both the traditional human strain H3N2 and the strain of the bird influenza H5N1. About this reports Sverdlovsk Rospotrebnadzor. Capability for the carriage of the strains of human influenza is noted also in bats. As studies showed, 3 forms of bats dwell in all regions of Ekaterinburg. Moreover the majority of the places of the inhabiting of these animals is located near the 5-storeyed houses of old building.

About komarah

The international scientific community during the past two decades seriously concerned about the dramatic increase in the incidence and spread of vector-borne diseases transmitted by mosquitoes krovosjosushchimi (arbovirusnye infection).

For example, only malaria in the world each year fell from 300 million to 500 million , and the number of deaths is 1-2.5 million The expanded nozoareal yellow fever, dengue fever, encephalitis, including West Nile virus (CCE), filariozov. Among the recognized causes of this dangerous trend analysts say global climate change, the growth of the number and nature mosquitoes, changes in the ecosystems under the influence of climatic and anthropogenic factors, socialno-demografic Russian developments (urbanization) around the world, contributing to the rapid spread of vector-borne infections.

Sverdlovskayaoblast, because of its geographical location at the border of Europe and Asia and the diversity landshaftno-klimatic Exploitation and altitudinal zones is a great site with a number of problems associated with krovosjosushchimi mosquitoes.

Thus, the average air temperature in the twentieth century in Eurasia was 0.6 ? C, in the Russian Federation-1.0 ? C and in Ekaterinburg and its vicinity in the past 20 years is 1.5 ? C. Troma mosquitoes very quickly and versatile reacting shifts in temperature. Study species of mosquitoes Sverdlovsk region for many years it is the HVAC FGUZ Hygiene and Epidemiology in Sverdlovsk oblasti> and, in the past two decades, the work is being carried out under the leadership of an Institute of Ecology plants and animals Uroran PhD Nikolayeva NV.

In Sverdlovsk region recorded 47 species of mosquitoes, and Sverdlovsk / Yekaterinburg urge - 40 types, and in the last 20 years of the presence in the region with 11 new species of mosquitoes. New species found in the region of the neighbouring regions, mostly west and south of the relatively quickly learn habitats within the administrative borders of Athens.

Epidemiological importance of the various types of blood mosquitoes as a whole for Russia, as well as its individual regions studied enough. According to reports, out of 119 species of mosquitoes former Soviet Union, only 40 species (34%) were confirmed status vectors. It must be emphasized that all environmentally plastic kulicid species, the dominant communities in the territories of cities fall within this group. In the mid-1990s witnessed an unprecedented growth in the populations of such species antropofilnykh as Anopheles messeae and Culex pipiens, in the center, which, to some extent, was the case in other regions of the Russian Federation. In turn, this led to the rise in the level of transmitted infections, such as malaria and landed out in the 1990s was simultaneously both in the Sverdlovsk region, as well other areas of the Russian Federation. These environmentally plastic species resistant to the adverse effects of the environment and dominate the mosquito fauna in the vast territories of Russia and the neighbouring CIS countries.

Of arbovirus diseases transmitted by mosquitoes, to the Urals and western Siberia, special interest, first and foremost, viruses serogroup California encephalitis : automobile, encephalomyelitis, Zaitze-beliaka and possibly viruses Sindbis, Batan, Omsk hemorrhagic fever.

Typically, in the temperate latitudes of illness (often with no clearly vrajennah clinical symptoms) 0-20% of the population. In the north, the same proportion of the transmitted rises to 60-70%. In the north, the Sverdlovsk region in the early 1990s antibodies to the virus encephalomyelitis were found in 60% of the surveyed people, including from 37 patients diagnosed with CNS unclear etiology. It is also part of mosquitoes (mostly kind Ochlerotatus) in the virus transmission Tick-borne encephalitis. However, diagnosis, in particular, encephalomyelitis viruses in the field and in the Russian Federation as a whole is unsatisfactory because immuno-molekularnae modern diagnostic methods require high cash costs.

Specialists, however, believe that up to 80% of all cases of the summer, which, in our medical institutions registered as ARI, by viral infection transmitted by mosquitoes. In this context, the greatest concern is a possible epidemic Junior territory of the region encephalitis caused CCE (virus West Nile). In the mid-1990s, CCE outbreaks were reported in a number of countries in Western and Southern Europe, and in 1996-1999. on the territory of the Russian Federation (Volgograd and Astrakhan regions and the Stavropol territory). It's important role in the transmission CCE among animals and from animals to humans 24 species of mosquitoes, among them, and frequently we species-Ae.vexans, Oc.caspius, An.claviger, An.messeae, Oc flavescecs, Ae.cinereus, Cx.modestus, Cx.territans, Cx.pjpiens. There is a virus found in birds, and antibodies to it - the widely number of people, including in regions located neda-leko of the Sverdlovsk region (Samara region and Tatarstan). Deaths from CCE is in the Russian Federation 10% of the victims, mostly people older age group (over 60 years) and young children.

In most regions of the Russian Federation mosquito encephalitides, including CCE, physicians diagnosed as limfocitarnyi meningitis. There is always an outbreak there in the second half of the summer and usually indicates that the town contacted pribrejno-vodnami biocenoces which, in contrast, are places of mass invasion of mosquitoes, and other CCE-birds. The massive lichorakopodobnykh diseases of children in fields of Sverdlovsk (formally diagnosed as meningitis limfocitarnyi) for the past 10 years, records almost every year.

Based on data Ierij UD RAS in the Middle Urals noted more than 300 species of birds, more than 78% remained in the Mediterranean and North Africa, where they could be infected CCE from birds to the local fauna through blood mosquitoes. Shown the role of bats in raznose CCE as well as the special study three types of bats live in all parts G.catherinburga, with the majority of seats between these animals are located near the storied houses older buildings. The roofs of houses and sheds migratory birds (Swifts), which can be carriers of CCE. And, most importantly, it is submerged podwalam such buildings back the urban populations Cx.pipiens mosquito, which feeds on birds, and other mammals, and there is a high antropofilnostew. It is also part of the mosquito species in the transmission of HCV C. Finally, the Russian virologists vividly illustrated by the blood of mosquitoes carrying the virus influenza group A, which applies to both traditional human strain H3N2, and H5N1 avian influenza virus. The ability to noyestvu human strains of the flu and also with the Bats.

The marked change in the size and species composition invasion of mosquitoes in the territory of Yekaterinburg and Sverdlovsk Oblast point to the relevance of extensive environmental monitoring, strengthening the fight against mosquitoes and the health control arbovirusnami infections.

Re: Russian Scientists Prove Mosquitoes, Bats Are Avian Influenza Vectors

so, they found some influenza-A in the blood of mosquitoes.
Their own blood, or the blood which they sucked ?

H3N2 doesn't survive in human blood, I read.

Are their cases of H2M2H or B2M2H ?

how many mosquitoes were examined in that area, how many had
flu-A ?

Re: Russian Scientists Prove Mosquitoes, Bats Are Avian Influenza Vectors

Considering the long list of mosquito-borne diseases, the possiblity of influenza shouldn't be too surprising.

From http://www.sutter-yubamvcd.org/Mosq.%20borne.htm

.....throughout history, more people have died of mosquito-borne diseases than from any other single cause of mortality, including wars and famine. But only in the last 100 years has science been able to prove that mosquitoes can transmit important pathogens of man and animals....

However, compared to the normal influenza small droplet routes - sneezing, coughing, etc., I would suspect that mosquitos may be more responsible for the odd case of flu, unless there is a large infected population for them to bite.

Re: Russian Scientists Prove Mosquitoes, Bats Are Avian Influenza Vectors

Everyone,
I have forwarded this thread, along with the PDFs of the Pennsylvania and Australian issues, to the University of Florida mosquito gurus. They will peer review the papers and read the threads and get back to me with their opinions.

I also told them about the dengue and chikungunya threads on the site. Maybe they will dial in and comment and get hooked as we are all hooked. Also, I was in an elevator here at the Capitol the other day when it was Mosquito Eradicator day or something like that. Anyway, all these mosquito control people were in the elevator when I got in, so I said "Get that Chikungunya virus! " and they all laughed appreciatively. That's FluTrackers! Educating the planet.

Re: Russian Scientists Prove Mosquitoes, Bats Are Avian Influenza Vectors

This is seriously bad news. Not unexpected to a logical mind; completely surprising to a forgetful one.

Here in Winnipeg the Chief Medical Officer's weekly news releases on the state of West Nile, the number of Culex in traps, and the decision for widespread fogging, are followed religiously.

I wonder what's faster and more effective transmission - one infected human on an airplane, or many infected mosquitoes blown from city to city.

Time to hug my kids.

Re: Russian Scientists Prove Mosquitoes, Bats Are Avian Influenza Vectors

Some mosquitos can fly for miles, while others travel only a few hundred feet in their lifetime. Here, mosquitos magnets can effectively eliminate them from up to an acre per machine.

I can avoid mosquitos better than people......so I'll worry more about people.

Mosquito magent machine ??? Surely you jest?

Don't some mammals have a bit of hematite in their snouts for finding magnetic north?

Jest?....no way, I'm serious - I LOVE these machines!

They are the absolute best defense against mosquitoes I've ever seen.
