Tuesday 31 December, 2019. The start of what has now been declared by the World Health Organization a “global health emergency”.
A sixty one year old man in Wuhan, China visited a local hospital presenting with pneumonia. This seemingly common problem only lead to the unraveling of a more sinister illness that has taken the lives of 170 and infected more than 7000 others (data as at Friday 31 January 1300 hours). This virus has received much attention from its rapid spread to 18 other countries, with cases in France and the USA, according to the World Health Organization. So, what is there to know about this new epidemic?
Coronavirus, named for its crown-like appearance, is part of a group of viruses that affects mammals and birds. SARS (Severe Acute Respiratory Syndrome) is a member of this group. Interestingly, contrary to physiological understanding of viruses, this group of viruses is considered both living and non-living. Speculations that this new strain of coronavirus, 2019-nCOV, arose by zoonosis from bats or snakes remain to be proven. Other theories suggest seafood in China may have been a main contributor to the spread of this virus.
Transmission involves inhalation of an infected person’s respiratory secretions or physical contact with infected individuals or surfaces. Dr Isaac Bogoch, an Infectious Diseases Specialist at the University Health Network claims “the ease of transmission is still unknown”. The most concerning thing about the coronavirus is its symptoms. Mimicking symptoms similar to a common cold can cause infection with the virus to be overlooked and mistaken for an influenza virus, especially in countries in the flu season. Early reports demonstrate that people sixty years and above have higher fatality rates and experience harsher symptoms, including pneumonia and sometimes kidney failure. This can be attributed to the fact that this age group is generally immunocompromised.
