Symptoms of a flu typically last for around five to seven days. For some older adults, particularly those with high risk factors, the flu may last one to two weeks. Some have reported experiencing cough and fatigue for up to three weeks.
Older adults are at higher risk of serious flu and flu-related complications including pneumonia and hospitalization. But there are also other risks that may not be as obvious—flu increases the risk of heart attack by 3-5 times and stroke by 2-3 times in the first 2 weeks of infection for those 65+.
In an older person, feeling weak or confused may be the only sign of having the flu. Influenza can become a life-threatening illness in older adults and other high-risk groups of people.
You should make a full recovery within 2 weeks – while your body may have fought off the infection successfully, you may not feel 100% for up to 2 weeks after being infected. Most of your symptoms should have subsided by this point, but it’s normal to feel weak and tired while your body recovers from the infection.
Common side effects may include:
According to new research, the elderly are more susceptible to influenza because their immune systems have trouble recognizing new viral strains. The findings, published in the journal Cell Host & Microbe, may help researchers design more effective flu vaccines for the elderly.
9 Tips to Ease Flu Symptoms
The proper functioning of influenza-specific T cells is critical for efficient clearance of the virus from the lungs. When T cell function declines, such as with increasing age or during use of immunosuppressive drugs, viral clearance is delayed. This results in a prolonged infection and greater lung damage.
The great majority of people with coronavirus will have mild or moderate disease and will make a full recovery within 2-4 weeks. But even if you are young and healthy – meaning your risk of severe disease is low – it is not non-existent.
How long does it take to recover? The COVID-19 recovery period depends on the severity of the illness. If you have a mild case, you can expect to recover within about two weeks. But for more severe cases, it could take six weeks or more to feel better, and hospitalization might be required.
Here are 12 tips to help you recover more quickly.
Also, headache, fatigue and soreness are common side effects that can last up to three days. Rarely, people with certain allergies can go into anaphylaxis after the flu shot. “It’s very rare but, sometimes, you can have a very serious reaction.
Some side effects that may occur from a flu shot include soreness, redness, and/or swelling where the shot was given, headache (low grade), fever, nausea, muscle aches, and fatigue. The flu shot, like other injections, can occasionally cause fainting.
While the flu shot cannot cause you to become sick with the flu, your immune system still recognizes what’s been injected into you as foreign. As a result, it produces an immune response, which leads to the soreness or swelling that occurs near the injection site.
