Viruses in humans symptoms

These include fever, lethargy, lack of appetite and coughing. Some people also have reported runny nose, sore throat, eye irritation, nausea, vomiting and diarrhea.

Swine influenza has not been shown to be transmissible to people through eating properly handled and prepared pork pig meat or other products derived from pigs. Influenza viruses can be directly transmitted from pigs to people and from people to pigs.

These infections have most commonly been reported after close proximity to infected pigs, such as in pig barns and livestock exhibits housing pigs at fairs.

Infected pig cough or sneeze and droplets with influenza virus in them can spread through the air. If these droplets land in your nose or mouth, or are inhaled, you can be infected. There also is some evidence that you might get infected by touching a surface with virus on it and then touching your mouth or nose.

A third way to possibly get infected is to inhale droplets or dust containing influenza virus. Human-to-human transmission of variant flu viruses also has occurred, though this method of spread has been limited.

This kind of transmission is thought to occur in the same way that seasonal flu transmits in people, which is mainly through coughing or sneezing by people who are infected. People also may become infected by touching something with flu viruses on it and then touching their mouth or nose.

To diagnose variant influenza A virus infection, a respiratory specimen would generally need to be collected within the first 4 to 5 days of illness when an infected person is most likely to be shedding virus. However, some people, especially children, may shed virus longer. Since the H1N1 pandemic, state health departments have the ability to test for novel non-human influenza viruses.

However, if a variant influenza virus is suspected, it is sent to CDC for further testing. There are four different antiviral drugs that are recommended for use in the United States for the treatment of influenza: oseltamivir, peramivir, zanamivir, and baloxavir.
