 Support The DrudgeReport; Visit Our Advertisers  SARS virus may spread via sweat, food, sewage, touch: study Thu May 6, 2004 15:11:03 ET The SARS virus has been found in sweat glands and the intestine, according to a new study, which says that in theory the disease may spread via contaminated sewage, food or even a handshake, not just by airborne droplets. Pathologists from the First Military Medical University in Guangzhou, southern China, warn that if further research proves that Severe Acute Respiratory Syndrome (SARS) can be transmitted by these unexpected routes, the implications for public health are major. The results were remarkable, according to their study, which is published on Friday in a British peer-reviewed publication, the Journal of Pathology. As expected, they found that the lungs of SARS victims to be riddled with the virus: up to 49 percent of the tissue cells they viewed had been infected. Lead researcher Ding Yangqing said that, like the respiratory tract, the gastro-intestinal system could be "a primary target" for the virus. "This suggests that the gastro-intestinal system may also be an entry route for SARS-CoV (if it is) present in food or water. "Although there is no report of such transmission, caution should be exercised by the at-risk population during the SARS-CoV endemic season. This finding supports the hypothesis that SARS-CoV may be released into the environment via faeces from individuals" with the disease. As viral traces were found in the kidneys, urine may also theoretically transmit the disease. Leaking sewage has been linked with Hong Kong's biggest outbreak of SARS. A total of 321 people, living in 15 blocks in the Amoy Gardens high-rise housing estate in Kowloon, fell sick in March and April last year. Ding also noted that the virus had, for the first time, been found in sweat gland cells in the skin. "This suggests another route of transmission for SARS-CoV, since this virus may be excreted in sweat and infect other people who are in direct contact with the patient's skin." The repercussions for public health may be far-reaching, the study warns. If, for instance, skin contact is confirmed as a transmission route, it would mean that SARS patients may have to wear gloves, disposable gowns and eye goggles, in addition to a full N95 face mask, to avoid kissing or touching other people. SARS last year caused almost 800 deaths worldwide from some 8,000 infections, most of them in China and Southeast Asia, before it was halted by quarantine policies. There is still no cure or a vaccine. In a smaller outbreak linked to handling of the virus in a laboratory, nine people have been diagnosed with the disease in China in the past few weeks, prompting the Chinese authorities to isolate hundreds of people. |
