Dr Le Van Tan in OUCRU, in collaboration with the Hospital for Tropical Diseases and the Department of Health, has shown that it is common for people who are infected with the virus that causes COVID-19 (SARS-CoV-2) to have no symptoms whatsoever. By testing quarantined people in Vietnam, his team was able to detect asymptomatic individuals. The virus disappeared faster from the bodies of the asymptomatic carriers than from that of symptomatic individuals, but it appeared that some of them still managed to pass the infection on to others.

First-of-its-kind study found equine antitoxin is safe and effective for the treatment of tetanus in adults

A first-of-its kind randomised controlled trial compared two different antitoxin treatments for tetanus. A comparison of human and equine intramuscular antitoxin in adults found that intramuscular equine antitoxin is safe and effective for treating tetanus in adults. Addition of additional intrathecal (spinal) antitoxin does not add any benefit compared to treatment with intramuscular antitoxin alone.
