The coronavirus (COVID-19) outbreak came to light when on December 31, 2019, China informed the World Health Organization (WHO) of a cluster of cases of pneumonia of an unknown cause in Wuhan City in Hubei province. On January 9, 2020, the WHO issued a statement saying Chinese researchers have made “preliminary determination” of the virus as a novel coronavirus.

Since then, more than 3,000 deaths have been reported due to COVID-19 across the world. Cases have been reported from more than 80 countries, including India. The virus has acquired the ability to spread among humans, with cases of human-to-human transmissions being reported first in Vietnam and Germany.

With the overall cases worldwide rising rapidly, the WHO has declared the outbreak a global health emergency.

COVID-19 symptoms can include fever, cough and shortness of breath. The illness also causes lung lesions and pneumonia. Milder cases may resemble the flu or a bad cold, making detection difficult. Chinese researchers have shared the whole genome sequence of COVID-19, however apart from some basic details, not much is known about the virus in terms of its source, precise duration of incubation, severity, and what makes it quite easily transmissible.
