So far, the flu season has not been as bad as the one last year, but some young and middle-aged adults still developed severe cases of influenza, the Centers for Disease Control and Prevention (CDC) stated.
On February 1, the Centers for Disease Control and Prevention announced that although nationwide there are not as many flu cases as in 2015, they are expected to increase across the United States in the coming weeks. There is already high activity of the flu in some specific areas in the country, the CDC reported.
Currently, the most widespread flu strain is H1N1 – subtype of influenza A virus that was the most common cause of flu among humans in 2009.
The agency said that there were several reports of young adults and middle-age adults who had developed cases of severe influenza. Some of these people were admitted to the intensive care unit, and some even died. According to the Centers for Disease Control and Prevention, most of those patients had not received this year’s influenza vaccine.
Every patient who is hospitalised for suspected flu should be given antiviral medication, the CDC stated. Before beginning the treatment, doctors should also not wait for a test to confirm that an infection is indeed influenza, the Centers for Disease Control and Prevention advised.
In general, most U.S. states have reported minimal flu activity so far. Moderate flu illness has been reported in the following three states: Maryland, Arizona, and South Carolina. High influenza activity has been reported in Puerto Rico.
About 2.1 percent of people – which also happens to be the national baseline for flu visits – visited the doctor because of an influenza-like illness form January 10 to January 16. The Centers for Disease Control and Prevention explained that when the overall doctor’s visits for flue reach or exceed that threshold (of 2.1 percent), that usually marks the beginning of flu season.
The rate for influenza hospitalisation in the United States is currently 1.8 hospitalisations per 100,000 individuals. Last year, the rate was a lot higher: thirty-six hospitalisations per one hundred thousand individuals.
Indicators of increase in flu severity this season will continue to be monitored by the Centers for Disease Control and Prevention, the agency said.
The Centers for Disease Control and Prevention stated that everyone six months and older should receive an influenza vaccine, and even now it is not too late to get one.
