Human H1N1 virus found in African livestock

Image
Researchers at the University of California, Los Angeles, have located the H1N1 virus in animals by conducting nasal swab tests and taking blood samples from domestic pigs in the Cameroon region of Africa.

In one northern Cameroon village, researchers found two pigs with an active infection and throws of others with past infection. In total, 89 percent of the pigs studied in this region had H1N1 virus exposure.

Using an enzyme-linked immunosorbent assay (ELISA) test, the researchers discovered that the pigs had the human H1N1 strain. The virus was identical to the strain that infected people in San Diego during the previous year.

During the spring of 2009, the global population was sent into a frenzy over the spread of a new strain of swine flu called Influenza A, or H1N1. Over 200 countries had citizens infected with the virus, and by June 11, the World Health Organization declared H1N1 to be the first worldwide pandemic in the past 41 years.
