Many of us may believe that spring marks the end of flu season, but that’s not quite the case. While flu season typically peaks between December and February, according to the Centers for Disease Control (CDC), there are cases that occur throughout the year. In recent weeks, health officials in Michigan have reported an increase in influenza activity in the southeast and southwest regions. Across the country and in Michigan, Influenza A is the main type in circulation. Flu activity is still lower than “normal,” but the virus can pose a risk – especially to certain groups and those with compromised immune systems. To avoid the spread of flu and stay healthy as you head into the summer months, it’s important to remember to frequently wash your hands, cover mouths when coughing and stay home if you’re sick, as well as keeping up to date with flu vaccines.
What is Influenza A?
There are two main types of the influenza virus that cause severe illness in humans: Influenza A and Influenza B. Influenza A has several types, including H1N1 and H3N2. Influenza A can cause severe flu infections in children and adults. It’s a highly contagious, respiratory illness that spreads through the tiny drops of bodily fluid shared by talking, sneezing or coughing.
What are the symptoms of Influenza A?
Symptoms come on suddenly. Influenza A often has the same symptoms of Influenza B:
- Congestion or runny nose
- Fever or chills – though not everyone will experience fever
- Muscle or body aches
- Some individuals may experience vomiting and diarrhea, though this is more common in children
- Sore throat
Symptoms should resolve in under two weeks – but complications can develop. They can be moderate, like an ear infection, or serious, like pneumonia. Some individuals are at a higher risk of complications from the flu:
- Children, especially young children and those under the age of 2 years
- Pregnant women
- Adults age 65 years and older
- Individuals with underlying medical conditions
What’s the best way to prevent Influenza A?
Flu vaccines are the best way to prevent Influenza A and B. It’s not too late to receive a flu shot, especially if flu is still prevalent on our communities. Only 32% of Michigan residents have received a flu shot for this season, which spans from fall 2021 to late spring 2022. Everyone ages six months old and up should receive a flu shot each flu season. Flu shots can be obtained at the same time as other vaccines, including the COVID-19 vaccines. Pregnant women should receive a flu shot during each pregnancy. Find a flu shot near you.
