The H3N2 flu virus could also lead to pneumonia, just like the Spanish flu virus.
Washington state reported high activity levels, the most severe on the scale developed by the Centers for Disease Control and Prevention. Nationally, as of mid-December, at least 106 people had died of the infectious disease. Cases of the flu are particularly increasing in the northern portions of the state, including the Panhandle.
The hospital is asking people with symptoms of upper respiratory infection, including a cough, runny or stuffed nose, or fever, along with children under the age of 12, to refrain from visiting hospitalized patients. The state's warmer temperatures typically mean people are less confined indoors during the winter months. So some parts of the country may have rougher flu seasons than others, depending on the strain.
Douglas County health experts don't know when the flu will peak.
Anmed says there's been 484 positive flu cases in the last 7 days, compared to just 37 cases for the first nine days of January. That's four times more people compared to this time past year. She encourages everyone to get a flu shot. The best way to prevent the flu is by getting a flu vaccine each year.
"Our research highlights the urgent need to develop more broadly-protective "universal" influenza virus vaccines - capable of providing protection against both seasonal and pandemic influenza strains".
The CDC said the flu vaccine is only about 30 percent effective this year because the H3N2 virus tends to mutate rapidly. Studies show that for children, a shot can significantly reduce the risk of dying.
State health officials report that the most common influenza type identified this season is Influenza A H3. It takes about two weeks to take effect.
"This is likely to be due to the lack of facilities, antibiotics and vaccines available".
New data analysis suggests that people born at the time of the 1957 H2N2 or Asian Flu pandemic were at a higher risk of dying during the 2009 H1N1 Swine Flu pandemic as well as the resurgent H1N1 outbreak in 2013-2014.
It's time to wash those hands.
While children and people over 65 are most vulnerable, the flu can have complications or be fatal to people of all ages. Remaining hydrated, eating nutritious foods and exercising also can help strengthen your immune system.
The hallmarks of flu are fever and body aches that accompany cough and congestion, Bergen said. If you feel sick, don't go to work or school and seek medical help. So paramedics can't get back on the road to answer more 911 calls, said Kay Fruhwirth, Los Angeles County's assistant director of emergency medical services.
Ehresmann noted that even in a perfectly matched year, the vaccine will not prevent every case of flu.
