Concern is growing as an outbreak of influenza sweeps across the country, claiming the lives of 22 people and sending 75 to intensive care units.

The strain of the flu, which has been identified as H3N2, is known to be particularly severe and can cause serious complications even in otherwise healthy adults.

What is H3N2?

H3N2 is a strain of the influenza A virus that first emerged in Hong Kong in 1968.

It is one of the most common strains of the flu and is known to cause severe illness in some people, particularly the elderly, pregnant women, and those with weakened immune systems. H3N2 is also known to mutate rapidly, which means that the vaccine developed for one season may not be as effective in preventing illness in subsequent years.

How is the Flu Spread?

The flu is highly contagious and can be spread through the air when someone infected with the virus coughs or sneezes. The virus can also be spread by touching a contaminated surface and then touching your mouth or nose.

It is important to practice good hygiene, such as washing your hands frequently, covering your mouth when you cough or sneeze, and avoiding close contact with people who are sick in order to prevent the spread of the flu virus.

Symptoms of the Flu

Symptoms of the flu can vary depending on the person and the severity of the illness, but typically include:.

Fever
Cough
Sore throat
Runny or stuffy nose
Headache
Muscle or body aches
Fatigue

Some people may also experience vomiting and diarrhea, although this is more common in children than adults.

If you think you have the flu, it is important to stay home and avoid contact with other people in order to prevent the spread of the virus. You should also:.
