About Coronavirus (2019-nCoV)
Novel coronavirus, denoted 2019-nCoV by the WHO and also known as Wuhan coronavirus, Wuhan seafood market pneumonia virus and Wuhan pneumonia, is a positive-sense, single-stranded RNA coronavirus first reported in 2019. It was initially identified during mid-December 2019 in the city of Wuhan in central China, as an emerging cluster of people with pneumonia of unknown cause, linked primarily to stallholders who worked at the Huanan Seafood Market, which also sold live animals. Chinese scientists subsequently isolated a new coronavirus, designated 2019-nCoV, which has been found to be at least 70% similar in gene sequence to SARS-CoV. A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
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.
These viruses are zoonotic, which means they are transmitted from animals to humans.
While the exact source (i.e. the animal from which it started) of 2019-nCoV is yet to be identified, other strains of coronoviruses have previously been seen to be transmitted from civet cats to humans (in the case of SARS-CoV) and from dromedary camels to humans (in the case of MERS-CoV).
According to WHO Western Pacific, information about newly reported 2019-nCoV infections suggests there may now be sustained human-to-human transmission. But more information and analysis are needed on this new virus to understand the full extent of human-human transmission and other important details.
On 15 January 2020, the WHO published a protocol on diagnostic testing for 2019-nCoV, developed by a virology team from Charité Hospital in Germany.
No specific treatment for the new virus is currently available, but existing anti-virals could be repurposed.
Limited information is available to characterize the spectrum of clinical illness associated with 2019-nCoV. No vaccine or specific treatment for 2019-nCoV infection is available. As of January 18, 2020, the FDA has not approved a coronavirus preventive or therapeutic vaccine. And, the World Health Organization has listed it as a top target for vaccine development by the Coalition for Epidemic Preparedness Innovations.
Global reported cases
As of 21 January 2020, 285 confirmed cases of 2019-nCoV have been reported from four countries including China (278 cases), Thailand (2 cases), Japan (1 case), United States (1 case), Taiwan (1 case) , Macau (1 case) and the Republic of Korea (1 case)
India on Alert
Till now no case has been reported in India. India has hiked the level of alert at its airports in the wake of the coronavirus epidemic in China. The government has directed screening of passengers arriving from China and Hong Kong at seven airports including at Bengaluru, for symptoms of Coronavirus (nCoV) disease. Thermal screening at international airports has been initiated according to the official press release. This request was made in keeping with the guidelines issued by the International Civil Aviation Organization (ICAO).
The government has also issued a travel advisory to its citizens, particularly for the city of Wuhan, the epicenter of the outbreak, where 500 Indian medical students are studying. Many of those students, however, are believed to have returned to India in recent days ahead of the Lunar New Year holiday, Asia’s busiest travel period when hundreds of millions are expected to be on the move.
An Indian woman working in China is believed to be the first foreigner to have contracted the disease. Preeti Maheshwari, 45, a teacher in an international school, was admitted to a local hospital in Shenzhen, a southern Chinese city, after falling seriously ill last Friday with pneumonia-like symptoms.
As per WHO, you should observe the following precautions:
i. Avoid close contact with live or dead farm and wild animals
ii. Avoid close contact with people suffering from acute respiratory infections
iii. Avoid consuming raw or undercooked animal products and handle raw meat and milk with care.
iv. Wash hands frequently, especially if there is a direct contact will ill people or exposure to their environment
v. If you have symptoms of acute respiratory infection, you should practice cough etiquette (maintain distance, cover cough and sneezes with disposable tissues or clothing and wash hands).
vi. If you are visiting a live animal market, a wet market or any animal product market, practice general hygiene like regular hand washing with soap and potable water after touching animals and animal products.
vii. Avoid touching eyes, nose or mouth with hands and avoid any contact with sick animals or spoiled animal products.
