The effectiveness of this year's vaccines are lower than last year, since the strain of influenza A responsible for most of the illness this year, H3N2, is more hard to target and leads to more drastic symptoms and a higher death rate.
About six in ten primary school children and 56 per cent of nursery aged children have already received the vaccine after the Health Department launched a "comprehensive" immunisation programme to try to cut the number of flu cases this season. Based on National Center for Health Statistics data, 8.2% of all deaths that occurred during the week ending January 13 were due to pneumonia and influenza.
"Since that time, I can tell you that our clinics and our ER have had some flu and flu-like activity". The hospitalization rate is now at 31.5 people per 100,000 US residents. "We still have a responsibility to protect public health and still have inspectors that will go out and inspect these healthcare facilities", Dr. Harris said. "We're really in historic territory, and I just don't know when it's going to stop".
So far, the dominant type of flu is H3N2, a strain associated with more hospitalization and death than other varieties, Tan said. She said that while we may be peaking with the current wave of flu, it's not unusual to have a second wave come through. "These viruses are often linked to more severe illness, especially among children and people over age 65".
CDC officials have said that flu season started early, in November. Influenza A H3N2 variant viruses (also known as "H3N2v" viruses) with the matrix (M) gene from the 2009 H1N1 pandemic virus were first detected in people in July 2011. Elderly people with the flu who experience confusion or weakness likewise require medical attention.
The researchers' team conducted a research in which they studied 142 confirmed cases of people with influenza during natural breathing, spontaneous coughing, sneezing, and prompted speech and analyzed the effects of naturally generating influenza aerosols.
Stratus Building Solutions has made it their mission to make workplace offices more resistant to the flu.
"We can't quite say yet", said Tina Tan, New Jersey's state epidemiologist.
The number of children dead is double what it was this time past year and state and local officials are urging people to get their flu shot.
If you get the flu, antiviral drugs prescribed by your doctor can be used to treat your illness.
