Swine Flu Koirala Surya

Abstract

Swine flu is a respiratory disease caused by influenza viruses that can be transmitted to humans

from pigs and result in a barking cough, decreased appetite, nasal secretions and listless behavior.

Swine flu viruses may change within one to four days so that they are easily transmissible among

humans. Symptoms of swine flu in humans are similar to most influenza infections: fever (100

F or greater), cough, nasal secretions, fatigue, and headache. The incubation period for the disease is about one to four days. Swine flu is contagious from about one day before the onset of symptoms to about five to seven days after symptoms develops; some patients may be contagious for a longer time span. The disease lasts about three to seven days with more serious infections lasting up to 10 days. It has a devastating effect on the economy and health of the communities even though it can be prevented and controlled with different measures like vaccines and antiviral drugs. The most serious complication of the flu is pneumonia.
