The lungs are the organs most affected by COVID‐19

Likewise, who are at higher risk of developing serious illness from COVID-19? Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.

Furthermore, 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.

In this regard, 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.

You asked, what are the complications of COVID-19? Complications may include pneumonia, acute respiratory distress syndrome (ARDS), multi-organ failure, septic shock, and death.

In what conditions does COVID-19 survive the longest?

Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).

Are people of a particular age vulnerable to coronavirus disease?

People of all ages can be infected by the COVID-19 virus.Older people and younger people can be infected by the COVID-19 virus. Older people, and people with pre-existing medical conditions such as asthma, diabetes, and heart disease appear to be more vulnerable to becoming severely ill with the virus.

Why are older people at significant risk of COVID-19?

Although all age groups are at risk of contracting COVID-19, older people face significant risk of developing severe illness if they contract the disease due to physiological changes that come with ageing and potential underlying health conditions.

Are smokers more likely to develop severe disease with COVID-19?

Tobacco smoking is a known risk factor for many respiratory infections and increases the severity of respiratory diseases. A review of studies by public health experts convened by WHO on 29 April 2020 found that smokers are more likely to develop severe disease with COVID-19, compared to non-smokers.

How long have coronaviruses existed?

The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.

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.

When did the coronavirus disease receive its name?

The International Committee on Taxonomy of Viruses (ICTV) announced “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” as the name of the new virus on 11 February 2020. This name was chosen because the virus is genetically related to the coronavirus responsible for the SARS outbreak of 2003. While related, the two viruses are different.

When was the official name of SARS-CoV-2 about COVID-19 announced?

ICTV announced “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” as the name of the new virus on 11 February 2020. This name was chosen because the virus is genetically related to the coronavirus responsible for the SARS outbreak of 2003. While related, the two viruses are different.

Can COVID-19 be transmitted through food?

There is currently no evidence that people can catch COVID-19 from food. The virus that causes COVID-19 can be killed at temperatures similar to that of other known viruses and bacteria found in food.

Can the coronavirus disease be transmitted through water?

Drinking water is not transmitting COVID-19. And, if you swim in a swimming pool or in a pond, you cannot get COVID-19 through water. But what can happen, if you go to a swimming pool, which is crowded and if you are close to other the people and if someone is infected, then you can be of course affected.

Can COVID-19 lead to mental and neurological complications?

Meanwhile, COVID-19 itself can lead to neurological and mental complications, such as delirium, agitation, and stroke. People with pre-existing mental, neurological or substance use disorders are also more vulnerable to SARS-CoV-2 infection ̶ they may stand a higher risk of severe outcomes and even death.

What does COVID-19 do to the cardiovascular system?

The virus can cause acute myocardial injury and chronic damage to the cardiovascular system.
