Federal health officials admitted that MRSA is killing more people every year in the U.S. than AIDS. You probably saw the news reports of the recent death of a Virginia student and the subsequent closing and cleaning of all area high schools. The excessive use of antibiotics is causing this problem to escalate all across the country.
On a similar note, researchers have found a strain of bacteria that causes ear infections in children has become resistant to all antibiotics approved for use in children. The report in the Journal of the American Medical Association notes that the shift in the bacteria known as serotype 19A occurred following the introduction of Prevnar in 2000.
