what is the source of 2019 novel coronavirus?
Answers
The Emergency Committee on the novel coronavirus (2019-nCoV) under the
International Health Regulations (IHR 2005) is meeting today to discuss whether
the outbreak constitutes a public health emergency of international concern.
• First confirmed cases of 2019-nCoV acute respiratory disease in Finland, India and
Philippines; all had travel history to Wuhan City.
• On 29 January, WHO held its third press briefing to provide update on the
situation. The audio can be found here.
• WHO recommends that the interim name of the disease causing the current
outbreak should be “2019-nCoV acute respiratory disease” (where ‘n’ is for novel
and ‘CoV’ is for coronavirus). This name complies with the WHO Best Practices for
Naming of New Human Infectious Diseases, which were developed through a
consultative process among partner agencies. Endorsement for the interim name
is being sought from WHO’s partner agencies, World Organization for Animal
Health (OIE) and Food and Agriculture Organization (FAO). The final name of the
disease will be provided by the International Classification of Diseases (ICD). WHO
is also proposing ‘2019-nCoV’ as an interim name of the virus. The final decision
on the official name of the virus will be made by the International Committee on
Taxonomy of Viruses.
Answer:
COVID-19
COVID-19 is the disease caused by SARS-CoV-2, the coronavirus that emerged in December 2019.
COVID-19 can be severe, and has caused millions of deaths around the world as well as lasting health problems in some who have survived the illness.
The coronavirus can be spread from person to person. It is diagnosed with a laboratory test.
COVID-19 vaccines have been authorized for emergency use by the U.S. Food and Drug Administration, and vaccination programs are in progress across the U.S. and in many parts of the world.
Prevention involves physical distancing, mask-wearing, hand hygiene and staying away from others if you feel sick.
How does the coronavirus spread?
As of now, researchers know that the coronavirus is spread through droplets and virus particles released into the air when an infected person breathes, talks, laughs, sings, coughs or sneezes. Larger droplets may fall to the ground in a few seconds, but tiny infectious particles can linger in the air and accumulate in indoor places, especially where many people are gathered and there is poor ventilation. This is why mask-wearing, hand hygiene and physical distancing are essential to preventing COVID-19.
How did the coronavirus start?
The first case of COVID-19 was reported Dec. 1, 2019, and the cause was a then-new coronavirus later named SARS-CoV-2. SARS-CoV-2 may have originated in an animal and changed (mutated) so it could cause illness in humans. In the past, several infectious disease outbreaks have been traced to viruses originating in birds, pigs, bats and other animals that mutated to become dangerous to humans. Research continues, and more study may reveal how and why the coronavirus evolved to cause pandemic disease.
What is the incubation period for COVID-19?
Symptoms show up in people within two to 14 days of exposure to the virus. A person infected with the coronavirus is contagious to others for up to two days before symptoms appear, and they remain contagious to others for 10 to 20 days, depending upon their immune system and the severity of their illness.
