Researchers track 2009 H1N1 virus changes
A US Department of Defense (DoD) notice said an emerging 2009 H1N1 flu group from recent outbreaks in Venezuela and Mexico's Chihuahua state bears watching because it has been linked to severe infections and deaths, including some patients who were previously vaccinated. The DoD analyzed recent samples from the area and included the findings in the US Air Force School of Aerospace Medicine's Apr 26 respiratory illness surveillance report. Researchers said they compared the primary Mexican strain with 2009 H1N1 viruses from other regions that are in other flu virus genetic databases. They reported that the Mexican group emerged very late and shows signs that it came from a single 2009 H1N1 strain and appeared briefly in 2010. Testing suggests it is not categorized with the H1N1 subclade that is still dominant in Europe or the Christchurch or Hong Kong subclades that are circulating. The DoD said the Southern Hemisphere's flu season may provide more clues about the emerging Mexican group.

Good find John.
What's your best guess for next fall with this new strain. Pandemic?
Best,

It is great to hear from you, my friend.
My best guess is not for a full blown pandemic but instead more like the nastiness we had years ago when they blew the vaccine selection and we got stuck with the A-fujian strain, and a lot of vaccinated people still got quite sick. The new swine strain will partially evade vaccine or prior infection but not totally. And some without prior vaccine or exposure, will then die. I could be wrong-sometimes pandemic strains instead return in a much more lethal form. But this is not my take yet.
Signs of an exceptionally early and bad flu year are already being seen in Australia. Now is about the last chance the authorities have to update the vaccine selection for Northern Henisphere production, and they APPEAR TO BE ASLEEP! Which is of course nothing new. Best, John L.

Good job John keeping your ear to the track on this thing.
Your response sounds good. I guess we'll see if this one has any legs soon enough.

Mutant Flu Strain Defying Northern Hemisphere Season End.
From CIDRAP;
May 9, 2011
WHO: Global flu activity pausing between seasons
Influenza activity is back to baseline or preseason levels across temperate parts of the Northern Hemisphere and has not yet started to increase in the temperate Southern Hemisphere, the World Health Organization (WHO) said in its latest flu update. In northern countries, one exception to the downward trend in flu indicators occurred in Mexico, where the proportion of respiratory specimens testing positive for flu increased from 9% to 14%. The increase involved mainly 2009 H1N1 viruses, following a recent outbreak of that strain in Chihuahua state. In Europe, northern China, and Japan, most or all of the few respiratory specimens that tested positive were influenza B. Flu activity also was generally low in tropical regions, though Ghana and Kenya reported ongoing transmission of 2009 H1N1 and type B viruses.

Any updates on this? I find it interesting. The conpiracty folks believe govt was tainting vaccines but that it would take 2-3 years for the breakout to happen. Not that I buy into it but it is interesting that it was the strain from that year. Just sayin!

An update from CIDRAP as I continue to track the flu, this time mainly re. the Southern Hemisphere:

Parts of Australia, Bolivia report increased flu activity
Health officials in Australia and Bolivia, two Southern Hemisphere countries just entering their winter flu season, are reporting an increase in flu detections, according to news and surveillance reports. Australia's health ministry said for the week ending May 13 that overall flu activity is low, though jurisdictions are reporting higher-than-normal numbers of lab-confirmed flu cases for this time of year, especially in the Northern Territory and Queensland. The Australian Medical Association's Queensland office said 1,600 flu infections have been reported so far this year, with 460 reported over the last 5 weeks, the Brisbane Times reported today. The group's president, Dr Gino Pecoraro, said the area is experiencing an unusually early start to the flu season, which he attributed to rainy weather that has kept people indoors where the virus can more easily spread.

Elsewhere, Bolivia's health ministry reported an increase in severe respiratory infections along with seven new 2009 H1N1 infections, Xinhua, China's state news agency, reported yesterday. The country's health minister, Nila Heredia, said respiratory infections have increased along with cold weather affecting La Paz, Oruro, Potosi, and Cochabamba provinces. She ordered Bolivia's health centers to take preventive measures to avoid an increase in 2009 H1N1 infections. The Southern Hemisphere's flu season typically runs from May through October.

Note: The Brisbane article link above states that flu is 50% higher in Australia already than last year at this time. Best to All, John L.

Good call John, although I know you've made no claims.
Researchers fear mutant flu strain
* Brigid O'Connell * From: Sunday Herald Sun June 26, 2011 12:00AM
MUTANT swine flu strains, resistant to existing treatments, have been detected in Australia by Melbourne researchers, sparking concerns of a new virus threat.
Swine flu has been stable since the 2009 pandemic, in which 24 deaths in the state were linked to the H1N1 virus.
But researchers from the WHO Collaborating Centre for Reference and Research on Influenza found that 30 per cent of H1N1 samples collected in Darwin and 10 per cent in Singapore, had the mutation S247N. This variant has lower resistance to current drugs, Tamiflu and Relenza.
Deputy director of the WHO Centre and senior author of the study, Dr Ian Barr, said the mutation was worrying.
"We'd prefer our viruses be completely susceptible to all our medications, so, it's always a concern when we see even low-level resistance to them in these viruses," he said.
Dr Barr said treatments generally would work against the new flu strain, but the greatest problem would be treating patients with more than one type of mutated virus.
A sample from a Perth patient who died in March revealed he had the new S247N mutation, but also another variant, H275Y, a combination 6000 times more resistant than the 2009 pandemic strain.

The risk factors of the H1N1 flu and the seasonal flu virus are similar with the exception of the younger people & the obese according to scientists reported in the journal PLoS Medicine.
However, they did say that 40% of the people who died didn't have any pre-existing chronic conditions, so that leaves me wondering if these scientists weren't talking out both sides of their mouths.
One of the symptom's of H1N1 for adults, in addition to the normal flu sumptoms, is vomiting & diarrhea. I think I had this in January & April of 2009, so I probably have some immunity to it. I passed out in our bathroom both times due to severe dehydration. All I can say about it, assuming that is what I had, was that the vomiting was wicked. If you get this, you'd be better off going to the emergency room rather than a doctor. (I had a co-worker who was diagnosed with H1N1 & another whose daughter was diagnosed with the H1N1 at the time.) All 3 of us were sick for 5 full days minimum. My co-worker didn't return to work for 2 full weeks. I had a fever for 8 days.

That was lucky - but your luck can run out at any time. The flu is no joke.

We had a woman at work that was out for 1 month with H1N1...no flu shot. She almost died.
