A couple of questions

How does COVID-19 affect the lungs?

As COVID-19 pneumonia progresses, more of the air sacs become filled with fluid leaking from the tiny blood vessels in the lungs. Eventually, shortness of breath sets in, and can lead to acute respiratory distress syndrome (ARDS), a form of lung failure.

What are the organs most affected by COVID‐19?

The lungs are the organs most affected by COVID‐19

How long does it take for symptoms of the coronavirus disease to appear?

On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.

What does COVID-19 do to the cardiovascular system?

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

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.

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%).

Can people with mild COVID-19 symptoms recover at home?

People with mild symptoms who are otherwise healthy should manage their symptoms at home. On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.
