There is still no cure. Patients are given supportive care for their symptoms, such as ventilators to aid breathing and fluids to prevent dehydration. Some researchers are searching for drugs that would block coronavirus infections; others are trying to develop a vaccine. Scientists have already sequenced the entire genome of the coronavirus, a major step in developing better treatments...
...know what those genetic factors are yet," says Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), "but they're not necessarily related to how sick the person is." Some experts suspect that superspreaders might have a more virulent strain of coronavirus or be co-infected with other microbes. Having multiple infections may, these scientists speculate, increase one's chance of passing on the disease...
...will the search for a vaccine. The biotech company GenVec announced plans last week to collaborate with NIAID to insert portions of the coronavirus genome into a weakened cold virus. If the proteins generated by these snippets are powerful enough to trigger an effective immune response, then the resulting vaccine might be successful. NIAID is also coordinating separate U.S. government efforts to develop vaccine candidates. And the U.S. Army Medical Research Institute for Infectious Disease is screening thousands of compounds to see if any might slow or stop the disease...
Scientists have identified a previously unknown virus in the coronavirus family as the primary cause of SARS. Coronaviruses often infect animals and until now caused only mild illness in people. It may turn out, however, that SARS results from simultaneous infection by several microbes...
