Re: A/Shanghai/71T/2009 acquired E627K

We have to see how epidemic will grow in Hong Kong region before conclude that H1N1 with E627K is more pathogenic than without.

I would like to remember that the pathogenicity determinants we have seen for H5N1 aren't present in novel H1N1 segments; it is also to note that the HA has not developed human-like receptors affinity through known mutations.

In the coming weeks, Hong Kong will enter in the peak seasonal epidemic time, so we will see the rate of new infections, as well as hospitalization and death rate.

Until now, there are not information by HK authorities about severe cases of novel influenza H1N1.

Re: Shanghai virus back in 1990

Originally posted by Nancy View Post

In case any one else out there is asking themselves, "what's Shanghai virus?" as I was, here is an OLD (1990) NY Times article about it. If it is irrelevant, feel free to delete.

I don't understand why, if Shanghai virus was a significant problem in the winter of 1989-1990, it wouldn't ALREADY have acquired the ability to spread easily during cold weather?? But you're saying this is new? And is Shanghai currently widespread? More than other strains of seasonal influenza? I'm confused.

Here's the article I found:

nytimes.com

http://www.nytimes.com/1990/01/26/us/us-health-agency-declares-flu-epidemic.html

U.S. Health Agency Declares Flu EpidemicBy WILLIAM K. STEVENS
Published: Friday, January 26, 1990

Centers for Disease Control declared yesterday [January 25, 1990] that a nationwide influenza epidemic exists and that it is the most widespread outbreak of the disease since 1984-85.

The flu, predominantly a strain called A-Shanghai, has been identified in every part of the country, and major outbreaks have been found in 35 states, epidemiologists at the centers say.

''We're in an epidemic,'' said Dr. Walter Gunn, a specialist in viral diseases at the centers, in Atlanta.

Based on Death Reports

The epidemic was declared on the basis of reports of deaths from 121 cities around the country. The proportion of deaths caused by influenza and pneumonia, a complication of the flu, was higher than expected for the second consecutive week, meeting the center's definition of an epidemic.

Because there is a lag between the onset of the flu and death and because it takes a week or so to report the deaths, the figures actually reflect the incidence of flu in late December and early January, said Dr. Stephen Ostroff, another epidemiologist at the centers in Atlanta.

Ordinarily, he said, the peak of the flu season comes in the middle to the end of February. This year, he said, ''the surge has come earlier, and we don't know whether it's going to subside early.''

Immunization Still Effective

Dr. Gunn urged flu immunization for people older than 65, those of any age who are in ill health ''and anyone who doesn't want to get the flu.''

Symptoms include a sudden onset of fever, chills, sore throat, headache, muscle aches and pains, general malaise and a dry cough. Dr. Gunn said simple gastrointestinal upset, which seems to have afflicted many in the New York region recently, is probably caused by viruses or infections other than the flu unless the stomach distress is accompanied by other flu symptoms.

When the flu kills people, epidemiologists say, it usually does so through pneumonia, which develops as a secondary infection. But it can also cause death through kidney failure and heart attacks, Dr. Gunn said.

Britain Hit by Same Strain

Dr. Gunn said A-Shanghai flu has been associated with more deaths and more instances of severe complications than other strains.

The A-Shanghai virus has also been responsible for Britain's worst flu epidemic in 14 years. Much of Europe, including the Soviet Union, has also been affected. In Britain last month, the epidemic put so many people in the hospital that London hospitals had to cancel thousands of routine operations and accept only emergency admissions.

In an average year in the United State, Dr. Gunn said, the flu plays a role in at least 20,000 deaths. ''This year we think it's going to be worse,'' he added. ''We don't know how much worse.''

In the outbreak in the winter of 1984-85, 57,400 deaths were attributed to the flu or pneumonia.

Linked to 7.6 Percent of Deaths

Last week, 1,132, or 7.6 percent, of the 15,090 deaths reported to the disease control centers from the 121 cities were attributed to flu or pneumonia. The percentage a week earlier was identical. Usually, the figure is between 6 percent and 6.5 percent for those two weeks, Dr. Ostroff said. Not since the 1984-85 season has that usual level been exceeded by as much as it was in the last two weeks.

The centers said that last week 18 states experienced flu outbreaks considered widespread, with outbreaks in counties accounting for more than half the state's population. Seventeen other states experienced regional outbreaks, with outbreaks in counties accounting for less than half the state population.

The epidemic did not begin in any specific part of the country, Dr. Gunn said. Rather, he said, ''it has been all over the place right from the beginning and has kept enlarging.''

The states reporting widespread outbreaks last week were Connecticut, New York, Massachusetts, Michigan, Wisconsin, Minnesota, Missouri, South Dakota, Nebraska, Virginia, North Carolina, Georgia, Mississippi, Oklahoma, Texas, Montana, Idaho and Arizona.

Those states reporting regional outbreaks were New Hampshire, Pennsylvania, Ohio, Iowa, Delaware, West Virginia, Kentucky, Tennessee, Alabama, Arkansas, Louisiana, Wyoming, Utah, Nevada, Alaska, Washington and New Mexico.

Two other varieties of flu, A-Taiwan and Influenza B, have also been detected in limited outbreaks, the first in Alaska, Arizona, Massachusetts and Iowa, and the second in Virginia and Nebraska, Dr. Gunn said. The symptoms are similar to those of A-Shanghai.

The virus described in the above article has nothing to do with the isolate being discussed on this thread (other than being isolated in Shanghai).

The PB2 is not due to reassortment. It is closley related to the other swine sequences in humans and therefore did not pick a PB2 from a distantly related virus (like human H1N1 or some other mammalian flu with PB2 with E627K).

Some will propose that this is yet another "random mutation" and the match of adjacent sequences with the H7N7 from the dead vet, or the Hong Kong outbreak in 1997 is a yet another "coincidence".

Hong Kong has two annual flu peaks: one during the winter (december to february, march) and one in the mid of summer (July, August).

This pattern could be common to other region with a similar climate or geographic location (ie: tropical regions)

2007 Airport passenger traffic:

Shanghai Pudong International Airport, 28,920,432
Shanghai Hongqiao International Airport, 22,632,962

That's over 60 million opportunities for the flu to hitch a ride to elsewhere.

Re: A/Shanghai/71T/2009 acquired E627K

It took only 46 days (since 1st diagnosed atypical pneumonia in Oaxaca) to acquire this change, although we should assume there were earlier undiagnosed cases.

Amazing.
