Information Sharing onThe Swine Influenza Virus (Source - One of the foreign Medical Groups)
Present Situation
This virus has currently affected citizens in the following countries: namely USA, Canada, Mexico, New Zealand, Australia and Middle East. Human deaths are recorded in Mexico only.
Background on this virus
Swine influenza, or “swine flu”, is a highly contagious acute respiratory disease of pigs, caused by one of several swine influenza A viruses. This virus is usually in the H1N1 subtype, but other subtypes are also circulating in pigs. The current virus is multi-strained and resistant to anti-viral drugs.
Transmission Method
The virus spreads among pigs by aerosols, direct or indirect contact and asymptomatic carrier pigs. Many countries routinely vaccinate swine populations against swine influenza. Outbreaks occur throughout the year with an increased incidence in the fall and winter in temperate zones.
People usually get swine influenza from infected pigs, however, some human cases lack contact history with pigs or environments where pigs have been located. Human-to-human transmission has occurred in some instances but was limited to close contacts and closed groups of people.
It is safe to eat pork and pork products from infected pigs as the virus is killed by cooking temperature (usually about 70 degrees Celsius).
Symptoms On Infection
Symptoms of swine flu in humans are similar to that of regular human seasonal flu. An early symptom is having a high fever, and this can be associated with cough, sore throat, breathlessness and severe body aches.
Treatment Anti-viral drugs may be administered by the medical practitioner for treatment of all probable cases.
There are also no vaccines against the swine influenza virus but the seasonal influenza vaccine is recommended. Anybody who is unwell should see a doctor immediately.
