When individuals come into contact with droplets from infected people, the flu virus is likely to spread. Individuals affected by this condition can spread it to others within a 6 feet vicinity, notes the United States Centers for Disease Control and Prevention.
There are three types of flu namely type A, B and C. All types of flu cause similar symptoms. However, type C is less severe when compared to the two other types of flu. The flu virus is spread when individuals infected sneeze, spit or cough around those who are healthy. The droplets emitted end up getting into contact with the mouth or nose of the healthy.
Touching surfaces that have these droplets may also increase the chances of spreading the virus to other people. To avoid infections, health officials encourage individuals to thoroughly wash their hands after touching surfaces that may be infected. Keeping away from the infected is another way to prevent the spread of the virus.
Some symptoms associated with the flu virus include development of a cough and a runny or stuffy nose. Other symptoms include mild or severe headaches, body aches in certain cases, chills, body weakness and nausea or vomiting. The flu and the common cold often have similar symptoms which is why professional diagnosis may be necessary, notes Flu.gov.
