Influenza infection, more commonly known as the flu, is a contagious respiratory illness caused by several different types of influenza viruses. Symptoms of the flu can range from mild to severe, and include fever, chills, cough, sore throat, runny nose, body aches, headache, fatigue, and sometimes diarrhoea and vomiting.
The flu is highly contagious and can spread easily from person to person through contact with the respiratory droplets of an infected person, such as when they sneeze or cough. It can also be spread through contact with contaminated surfaces or objects, such as doorknobs, counters, and toys.
The best way to protect yourself from the flu is to get a flu shot each year. Vaccination is the most effective way to prevent influenza infection and reduce the risk of serious complications. Other preventive measures include washing your hands often with soap and water, avoiding close contact with sick people, and staying away from crowded places.
If you do get the flu, it’s important to rest, drink plenty of fluids, and take over-the-counter medications to reduce fever and relieve discomfort. In some cases, antiviral medications may be prescribed to reduce the severity and duration of the illness.
Overall, influenza infection can be a serious and potentially dangerous health threat. Taking preventive measures, such as getting a flu shot and practicing good hygiene, is the best way to protect yourself and others from the flu.
