What is a coronavirus?
Coronaviruses are a large family of enveloped, non-segmented, single-stranded, positive-sense RNA viruses that circulate among animals including camels, cats, and bats. Coronaviruses derive their name from their electron microscopic image, which resembles a crown – or corona
What is COVID-19?
The disease caused by the SARS-CoV-2 virus is known as coronavirus disease 2019 – or COVID-19.
According to the Johns Hopkins Center for Systems Science and Engineering, as of June 26, 2020, there have been over 10.1 million confirmed cases of COVID-19 and 502,589 deaths worldwide (3) – but these numbers are still growing steadily (see Figure 4). Globally, the confirmed case fatality rate is above 5 percent – that is, one in every 20 people with a confirmed positive COVID-19 test has died of the disease.
How deadly is COVID-19?
The mean duration from symptom onset to death is 18 days. Case fatality rate (CFR), which is calculated by dividing the number of deaths by the number of known cases, has been reported at 6.4 percent worldwide – significantly higher in older patients. But CFR almost certainly overestimates the true lethality of the virus. The number of confirmed cases usually includes only people whose symptoms were severe enough to be tested, resulting in a severity bias. Epidemiologists estimate there are five to 10 times more people with asymptomatic infections. Additionally, the number of deaths may be inaccurate at the time of calculation because deaths typically occur one to two months after a person becomes infected and not all deaths are apparent at the same time. COVID-19 deaths that occur at home are underreported compared with those that occur in a hospital.
