Corona Virus: What You Need to Know

Corona virus-induced flu which originated at Wuhan, China is spreading fast. The deadly disease has been declared as a worldwide health emergency by WHO. Read more about the epidemic & learn how to prevent a potential infection.

The outbreak of 2019-novel coronavirus (2019-nCoV), a rapidly evolving epidemic that emerged in Wuhan, China has led to a quarantine of more than 50 million people. As China, the World’s most populous country has come to a lockdown, Public health experts are still unsure about how deadly or contagious coronavirus is, and whether it is also transmitted by people, who show no symptoms. With more than six countries having confirmed human to human transmission, World Health Organization (W.H.O) has declared it as a global health emergency, whilst cases in China and the resultant death toll continue to rise.  The confirmation of human to human transmission is a worrying factor considering the yearly migration in China on account of Chinese New Year festivities. Nearly 9500 cases have been confirmed in China with the death toll rising to about 213.


What is Coronavirus?

Coronavirus is a family of RNA virus which typically cause the common cold and upper respiratory infections. The name Coronavirus comes from the Latin word corona meaning crown. Under an electron microscope, Coronavirus has crown-like spikes on its surface. Three strains of Coronavirus are deadly: Middle-East Respiratory Syndrome (MERS), Severe Acute Respiratory Syndrome (SARS) and now the 2019-nCoV, which is a new strain, previously not seen in humans.

Coronaviruses are zoonotic, meaning they originate in animals and then spread to humans. Though not confirmed, current speculation is that the coronavirus spread from bats or snakes to humans and from thereon, human to human transmission took place. With a fatality rate of about 2.2%, it spreads through droplet infection, when an infected person breathes out, coughs or sneezes. It can also spread via contaminated surfaces like doorknobs or railings.



W.H.O has estimated the incubation period is somewhere around two to ten days before symptoms appear, but there can be anecdotal accounts of "symptomless spreading" by someone infected, but unaware. Since its emergence, the number of people infected by coronavirus doubles every 7.4 days, which shows its rapid spread.

Confirmed cases of 2019-nCoV have symptoms ranging from mild sickness to being severely ill and in some cases death. Symptoms include:

In severe cases, it may cause pneumonia, severe acute respiratory syndrome, kidney failure and death.


Where has 2019-nCoV been reported?

2019-nCoV was first reported in Wuhan, a major city in China’s Hubei Province. Although the exact source is not confirmed, initial reports suggest that it started at the Huanan seafood wholesale market in Wuhan. The virus then spread to many Asian countries, as well as Australia, Europe, North America, and the Middle East. India has reported its first case of the virus- a student from Kerala, who was studying in Wuhan.


Steps and Measures taken

There is no vaccine or treatment protocol in place for treating the new virus. The best way to prevent the infection is to avoid being exposed to the virus.

Wuhan, the heart of the outbreak, is completely sealed, transportation and airway restrictions are adopted and screening at airports is done to contain the infection from spreading. Voluntary evacuations of foreign nationals are underway.


Challenges ahead of us


Who are at risk?

Although all people are at risk of contracting the virus, people with reduced chance of survival are:


Precautions to be taken

W.H.O & Ministry of Health & Family Welfare, Govt of India has recommended the following measures to be observed to restrict the infection from spreading:

If you have been to China, or any other place identified with the outbreak of Coronavirus, and feel sick with fever or cough within 14 days, don’t hesitate to seek medical help right away and avoid close contact with others and wear a facemask.


The bottom-line

Given the quick spread of the disease, it is likely that the number of cases might increase, but there is no need to panic. Public health teams and Governments are gearing up to increase awareness and taking adequate steps and planning strategies to reduce the spread of the virus. Avoid sharing false information and verify any information from a reliable source.
