Highly infectious Norwalk flu is reported at Thornhill.Woods Public School at 341 Thornhill Wood in Thornhill. Parents are being urged to keep children with any symptoms at home. Some of the symptoms of Norwalk include diarrhea, vomiting, nausea, cramps, muscle aches, fatigue and fever. Symptoms usually dissipate after 24 to 48 hours. The scientific name for this flu is norovirus. The annual flu shot is no protection for norovirus.. Vaccine and treatment research of this bug have been limited because of a lack of understanding of norovirus within humans, but recent discoveries in mice have identified that certain biological factors can slow down or kill the virus. “Up until now vaccines have exclusively been using virus-like particles, but some new developments may make it possible to generate a live attenuated vaccine, which is pretty exciting,” ” say Megan Baldridge, a physician familiar with norovirus. “Having animal models and cell culture models to grow the virus and study how it acts a little more closely will help us better understand the virus and also think more about vaccination strategies.”
