Where was the first case of coronavirus disease outside of China?
Officials confirm a case of COVID-19 in Thailand, the first recorded case outside of China.27-Apr-2020
The first known case was identified in Wuhan, China, in December 2019.
Where was COVID-19 first discovered?
The first known infections from SARS-CoV-2 were discovered in Wuhan, China. The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel severe acute respiratory syndrome coronavirus. It was first isolated from three people with pneumonia connected to the cluster of acute respiratory illness cases in Wuhan. All structural features of the novel SARS-CoV-2 virus particle occur in related coronaviruses in nature.
When was COVID-19 first reported?
On this website you can find information and guidance from WHO regarding the current outbreak of coronavirus disease (COVID-19) that was first reported from Wuhan, China, on 31 December 2019.
Reinfection with the virus that causes COVID-19 means a person was infected, recovered, and then later became infected again. After recovering from COVID-19, most individuals will have some protection from repeat infections. However, reinfections do occur after COVID-19.
Which Omicron specific COVID-19 vaccine was approved by the UK?
The MHRA said the Spikevax vaccine met the standards of safety, quality and effectiveness. During trials, the vaccine triggered a strong immune response against both strains. In an analysis, the bivalent vaccine was also found to generate a good immune response against the omicron sub-variants BA.4 and BA.5.17-Aug-2022
Most people who recover from COVID-19 find their sense of smell returns in a few weeks. But for others — up to 7%, according to one estimate1 — the loss can persist for months or even years.22-Jun-2022
Who issued the official name of COVID-19?
The official names COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020.
The virus primarily spreads between people through close contact and via aerosols and respiratory droplets that are exhaled when talking, breathing, or otherwise exhaling, as well as those produced from coughs or sneezes.
How was the COVID-19 vaccine developed so quickly?
See full answerDeveloping a vaccine generally involves years of research. First, we need a vaccine candidate that is evaluated in animals for its safety and efficacy. After a vaccine candidate passes a pre- clinical trial, it enters the clinical trial phase. While scientists have worked round the clock in the laboratory, even regulatory approvals which used to take several months have been fast tracked. It helped eliminate all the time lapses between the pre-clinical and clinical trial stages. Earlier, the vaccine development involved a series of steps, but in the case of the coronavirus vaccine, the scientists and regulators worked in tandem, accelerating the whole process without compromises on any protocols and any step.
Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that can range from mild to lethal.
Is COVID-19 caused by a virus or a bacteria?
The coronavirus disease (COVID-19) is caused by a virus, NOT by bacteria.
Covid 19 belongs to the coronavirus family, which also includes the SARS virus (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Symptoms) virus. The family of Coronavirus includes virus strains that cause the common cold and flu.
What is the natural reservoir for SARS-CoV-2?
The most likely ecological reservoirs for SARS-CoV-2 are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified.21-Feb-2020
On 11 February 2020, the International Committee on Taxonomy of Viruses adopted the official name "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2).
What are some of the other names of the coronavirus that erupted in 2019?
A new outbreak of the coronavirus erupted in 2019 in China. Some other names attributed to the coronavirus are severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and coronavirus disease 2019 (COVID-19).
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.03-Mar-2020
How long is the incubation period for COVID-19?
The time taken by the symptoms to first appear on an infected individual. The incubation time for COVID-19 ranges from 1-14 days, most commonly being around 5 days.
Some of the primary symptoms to look for in a Covid 19 infected person are fever, dizziness, breathlessness, headache, dry cough ( eventually result in phlegm) and in a few cases loss in smell and taste. A few cases have also reported diarrhoea and fatigue.
How does COVID-19 affect the lungs?
Covid 19 directly impacts the lungs and damages the alveoli (tiny air sacs).
