When someone interacts with the community was suffering from the flu, he will be infected with the flu virus very quickly. A study showed that the spread of the flu virus apparently began before flu symptoms appear in the patient.

The study chose ferrets as its object, as if it is applied directly to humans, the virus is easily transmitted to others and will be very difficult to prevent an epidemic.

According to a report in the journal Public Library of Science ONE, to determine if the flu virus contagious before people who have been infected show symptoms, it can help the government in mapping out a plan to fight pandemic flu.

Previous studies using mathematical models predict that the transmission of the flu virus occurs after the onset of symptoms, but some occur earlier. Types of influenza virus used in this study are from the 2009 swine flu pandemic, which killed nearly 300,000 people around the world.

This is the first study to investigate the transmission of the flu virus with the object of experimental animals. Weasel used in flu research because ferrets are very susceptible to the flu virus and showing symptoms similar to humans.

Weasel has given flu shots put in contact with an uninfected ferret in a short period of time. Transmission occurs before the first symptoms experienced by raccoons that have been previously infected.

The researchers found that the ferret badger capable of transmitting influenza to others in just 24 hours after his own infection. Ferret-badger does not have a fever up to 45 hours after infection and start sneezing after 48 hours.

“These results have important implications for pandemic planning strategy. Based on this research note that the spread of the flu virus is very difficult to control, even with the early diagnosis of the symptoms,” says Wendy Barclay, a researcher and professor of medicine at Imperial College London, as reported by health . india, Friday (31.08.12).

Barclay also warned that doctors and nurses who do not get flu shots may increase the risk of transmission of influenza viruses in other patients because flu viruses can spread the infection before the sufferer knows that he has been infected.

These results are consistent with previous research that found that flu transmission is not started since someone sneezes but the virus through droplets released into the air when breathing normally.
