The head of the World Health Organization said on Tuesday that the global mortality rate for Covid-19, the disease caused by the new coronavirus, was 3.4 percent.


Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans. 

Coronaviruses are zoonotic, meaning they are transmitted between animals and people.  Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.

What is COVID-19?

COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.

Illness that started in Wuhan?

COVID-19 appeared in Wuhan, a city in China, in December 2019. Although health officials are still tracing the exact source of this new coronavirus, early hypotheses thought it may be linked to a seafood market in Wuhan, China. Some people who visited the market developed viral pneumonia caused by the new coronavirus. A study that came out on Jan. 25, 2020, notes that the individual with the first reported case became ill on Dec. 1, 2019, and had no link to the seafood market. Investigations are ongoing as to how this virus originated and spread.

This virus probably originally emerged from an animal source but now seems to be spreading from person to person. COVID-19 has been detected in people throughout China and 24 other countries, including the United States.

Symptoms and Preventions

Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.

Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.

How does COVID-19 spread?

People can catch COVID-19 from others who have the virus. The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales. These droplets land on objects and surfaces around the person. Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth. People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs out or exhales droplets. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick.

Coronavirus Global Mortality Rate

The head of the World Health Organization said on Tuesday that the global mortality rate for Covid-19, the disease caused by the new coronavirus, was 3.4 percent.

Tedros Adhanom Ghebreyesus, the organization’s director general, said in a news conference in Geneva that Covid-19 is deadlier than the seasonal flu, but does not transmit as easily. “Globally, about 3.4 percent of reported Covid-19 cases have died,” said Dr. Tedros. “By comparison, seasonal flu generally kills far fewer than 1 percent of those infected.”

The estimate most likely takes into account the growing number of infections being recorded outside China, mostly in South Korea, Iran and Italy.

Coronavirus outbreak, or COVID-19, has spread rapidly across more than 80 countries. There have been 28 confirmed cases in India so far, Union Health Minister Dr. Harsh Vardhan has said. Globally, there have been over 92,800 cases of novel coronavirus. At least 3,100 people have died so far — majority of them in China. Infections have steadily risen in Iran, Italy, Japan and South Korea. The outbreak is having a major impact on global economy and the stock market. 

Breakup of coronavirus cases in India:

Delhi: 1

Agra: 6 (Relatives of the Delhi patient)

Telangana: 1 (Bengaluru techie)

Kerala: 3 (All of them have recovered)

Jaipur: 17 (16 Italians and an Indian driver)

Total 94,249 Coronavirus Cases, out of which death toll is at 3,220 and Statistics of Recovered cases are 51,202.

In China, total 80,282 recorded, out of which total deaths are 2981.

In South Korea, total 5,621 recorded, out of which total deaths are 34

In Iran, total 2,922 recorded, out of which total deaths are 92

In Italy, total 2,502 recorded, out of which total deaths are 79

Officials in the United States have confirmed nine deaths and more than 100 cases, while Iran and Italy have recorded 92 and 79 deaths respectively. The total number of cases in Europe`s worst-hit country rose to 2,502 from 2,036 on Monday. China announced 119 new cases on Wednesday, along with 38 deaths, the lowest figures since at least Jan. 20.
