Novel Coronavirus

Coronavirus Identification and Tracing

Corona viruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they can cause mild to fatal respiratory infections. The common cold is a common illness in humans (it is caused by other viruses, mainly rhinoviruses), but the more deadly types are SARS, MERS, and COVID-19, which cause an on-going pandemic. They cause diarrhea in cows and pigs, and hepatitis and encephalomyelitis in rats. Coronaviruses belong to the subfamily Orthochoronavirin, in the family Coronaviridae, a sequence of nidoviruses and the ribavirin kingdom. They are viruses covered with a positive-sense single-stranded RNA gene and a nucleocapsid helical symmetry.

Important considerations for Contact tracing:

Contact is a person who is likely to get an infection from a positive case through any known transmission methods. If someone has a Covid-19 symptom, 2 to 14 days before the symptoms appear unless previously isolated. For asymptomatic or pre-symptomatic cases, the duration for contact tracing is taken from 2 days to 14 days after the date if not separated before sample collection.
