Influenza, or the flu, is a contagious respiratory infection caused by a variety of flu viruses. Symptoms of flu involve muscle aches and soreness, headache, and fever. There are a number of strains of the flu. Some types can make you very ill, while other types of flu cause milder symptoms. Read on to learn about the different types of flu.
Flu viruses enter the body through the mucus membranes of your nose, eyes, or mouth. Every time you touch your hand to one of these areas, you are possibly infecting yourself with a virus.
Type A flu virus is constantly changing and is generally responsible for the large flu epidemics. The influenza A2 virus (and other variants of influenza) is spread by people who are already infected. The most common flu hot spots are those surfaces that an infected person has touched and rooms where he has been recently, especially areas where he has been sneezing.
This animation from Elara illustrates how the flu virus penetrates you cells, injecting its RNA right into there. It’s a dramatic presentation of something too small for the naked eye to witness.
