Coronaviruses are a family of enveloped, single stranded RNA viruses, previously only known to cause the common cold in humans (Gladwin, Trattler, & Mahan, 2014). Surface projections look like a crown under electron microscopy, hence the name – coronaviruses. Three major strains: human coronaviruses (HCoV) 229E and OC43 and severe acute respiratory syndrome coronavirus (SARS-CoV) (Elliott, Casey, Lambert, & Sandoe, 2011); and the novel 2019 coronavirus (2019-nCoV). HCoV have a worldwide distribution and infections occur throughout the year, affecting all age groups equally. A SARS-CoV epidemic started in 2002 in southern China, from where it spread to Hong Kong, Vietnam, Singapore, Canada, Taiwan, Thailand and other parts of the world. The epidemic ended in 2003, affecting 8,500 patients (95% in Asia) with a mortality rate of 9.5%.The incubation period is 2–5 days for HCoV and 2–10 days for SARS-CoV. Transmission is by respiratory droplets, aerosols and possible faecal-oral route for SARS-CoV. Replication takes place in the epithelial cells of the respiratory tract and gut with development of strain-specific antibody. Asymptomatic shedding in faeces is common.
Copious puzzling school of thoughts concerning the 2019 novel Coronavirus (2019-nCoV) have arisen. This article aims at discerning the truth from the myths about this novel coronavirus.
- Coronavirus is an opportunistic infection
The belief that the virus infects only those individuals with an underlying ailment, thus the immunocompromised is not true. The virus infects everyone, the healthy and the sick. Everyone is at risk of infection by this virus.
- Flu shots can prevent the coronavirus
Yes flu and common cold are both respiratory illnesses and they exhibit similar symptoms but it worth noting that they are caused by different viruses. The influenza virus is different from the coronavirus and hence the flu vaccine cannot prevent infection by the coronavirus.
- Face masks can prevent infection by the coronavirus
Face masks have become very common in mainland China and Hong-Kong however it is important to note that the ordinary surgical face masks cannot protect against the novel 2019 coronavirus (2019-nCoV). A more specialized mask, known as an N95 respirator, can protect against the new coronavirus, also called 2019-nCoV. The respirator is thicker than a surgical mask but it is challenging to put these masks on and wear them for long periods of time. Specialists receive retraining annually on how to properly fit these respirators around the nose, cheeks and chin, ensuring that wearers do not breathe around the edges of the respirator (Geggel, 2020).
- Transmission is from a bat soup
There is no clinical evidence suggesting that the (2019-nCoV) came from the bat soup. The viral video of the woman eating bat soup has been claimed to be taken four years back in Palaui island.
- Coronavirus is deadlier than flu
Coronavirus causes common colds. Common cold and flu have similar symptoms; it can be difficult to tell the difference between them based on symptoms alone. In general, flu is worse than the common cold, and symptoms are more intense (CDC, 2019).
