What are the organs most affected by COVID‐19? The lungs are the organs most affected by COVID‐19
What is the origin of COVID-19? 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.

Can you get COVID-19 by touching surfaces?
COVID-19 can also spread by touching something that has the virus on it, then touching your mouth, nose or eyes with unwashed hands. You can transmit COVID-19 before you start showing symptoms or without ever developing symptoms.
Which types of settings does COVID-19 spread more easily?
The “Three C’s” are a useful way to think about this. They describe settings where transmission of the COVID-19 virus spreads more easily:
• Crowded places;
• Close-contact settings, especially where people have conversations very near each other;
• Confined and enclosed spaces with poor ventilation.
Can COVID-19 be transmitted through food?

Can masks prevent the transmission of COVID-19?
Masks should be used as part of a comprehensive strategy of measures to suppress transmission and save lives; the use of a mask alone is not sufficient to provide an adequate level of protection against COVID-19.
If COVID-19 is spreading in your community, stay safe by taking some simple precautions, such as physical distancing, wearing a mask, keeping rooms well ventilated, avoiding crowds, cleaning your hands, and coughing into a bent elbow or tissue. Check local advice where you live and work. Do it all!

If not possible: sleep in separate beds position yourselves head to toe keep the room well ventilated Use a separate washroom from the person in quarantine or isolation. If not possible, ensure surfaces and objects the person you’re caring for has touched are cleaned and disinfected after each use, like: toilets sink faucets
door handles Wearing a respirator Household members should wear a respirator (like an N95 or KN95) when sharing a space with the person who is in quarantine or isolation. This is even more important for household members that are: at risk of more severe disease or outcomes from COVID-19 living in an overcrowded settin

What are the symptoms of the new COVID-19 variant Ba 5?
At this time, symptoms from BA. 5 appear to be similar to those caused by other Omicron subvariants. Common symptoms include fever, runny nose, coughing, sore throat, muscle pain, and fatigue.

How long can Long COVID symptoms last?
Symptoms. People with post-COVID conditions (or long COVID) may experience many symptoms. People with post-COVID conditions can have a wide range of symptoms that can last more than four weeks or even months after infection. Sometimes the symptoms can even go away or come back again.
Can you have COVID and test negative?
Some people with mild infections may test negative on an antigen test, but positive on a PCR test. This would mean that they have COVID, but don’t have enough virus to turn an antigen test positive.
