What are signs and symptoms of the coronavirus disease?

What are signs and symptoms of the coronavirus disease?

Signs and symptoms include respiratory symptoms and include fever, cough and shortness of breath. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome and sometimes death.Standard recommendations to prevent the spread of COVID-19 include frequent cleaning of hands using alcohol-based hand rub or soap and water; covering the nose and mouth with a flexed elbow or disposable tissue when coughing and sneezing; and avoiding close contact with anyone that has a fever and cough.

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 are the organs most affected by COVID‐19?

The lungs are the organs most affected by COVID‐19

Can asymptomatic people transmit COVID-19?

Yes, infected people can transmit the virus both when they have symptoms and when they don't have symptoms. This is why it is important that all people who are infected are identified by testing, isolated, and, depending on the severity of their disease, receive medical care.

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 (

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.

What are the complications of COVID-19?

Complications may include pneumonia, acute respiratory distress syndrome (ARDS), multi-organ failure, septic shock, and death.

What is the difference between people who have asymptomatic or pre-symptomatic COVID-19?

Both terms refer to people who do not have symptoms. The difference is that ‘asymptomatic’ refers to people who are infected but never develop any symptoms, while ‘pre-symptomatic’ refers to infected people who have not yet developed symptoms but go on to develop symptoms later.

How is the COVID-19 disease transmitted?

COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles containing the virus. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors. Transmission can also occur if splashed or sprayed with contaminated fluids in the eyes, nose or mouth, and, rarely, via contaminated surfaces.

How long does the virus that causes COVID-19 last on surfaces?

Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.
