Swine flu cases jump to 113 in Indiana

Indiana health officials said on Wednesday that they have confirmed 113 H3N2 swine flu cases that have infected people from 18 counties throughout the state.

According to the U.S. Centers for Disease Control and Prevention, the virus has passed from sick pigs to people visiting agricultural fairs. The illness is more common in children than adults who may have resistance as a result of past swine flu outbreaks, the Los Angeles Times reports.

The H3N2 influenza causes a mild illness that is similar to a typical seasonal flu. Officials are keeping a close watch on the disease, however, to ensure that it does not adapt and become more transmissible between humans.

The Indiana State Department of Health said that investigators in the state have not found any cases of the disease in which it spread from human to human. The department said it would continue to monitor the matter. The state health department warned that it expected to report additional swine flu cases that would be confirmed during the week, the Los Angeles Times reports.

The CDC advised that people vulnerable to the flu should avoid sick people and pigs and wash their hands frequently to keep the disease from spreading. Sick pigs may exhibit symptoms similar to humans, including sneezing, runny noses and eyes, coughing and lethargy.
