Swine flu : Zoonosis
The 2009 flu pandemic is a global outbreak of a new strain of influenza virus, officially named “new H1N1” strain, first identified in April 2009 in Mexico, commonly called Swine flu.
Swine flu is a respiratory disease caused by viruses (influenza virus), that infect the respiratory tract of pigs and results in nasal secretions, a barking like cough, decrease appetite. Swine flu viruses may mutate (change) so that they are easily transmissible among humans. The symptoms of swine flu in humans are similar to most influenza infections such as fever (100º F/ greater), cough, nasal secretions, fatigue & headache.
Two anti-virus agents ZANAMIVIR and OSELTAMIVIR (tamiflu) have been reported to help prevent or reduce the effects of swine flu if taken within 48 hrs on the onset of symptoms.
"If neglected, Swine flu may lead to death of the infected person, hence treated as dangerous issue. And also WHO has raised the worldwide pandemic alert level to Phase 5".
