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.
What are the possible modes of transmission of COVID-19?
Transmission of SARS-CoV-2 can occur through direct, indirect, or close contact with infected people through infected secretions such as saliva and respiratory secretions or their respiratory droplets, which are expelled when an infected person coughs, sneezes, talks or sings.
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.
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 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.
16 related questions foundWhat should I do if I have symptoms of COVID-19?
If you have symptoms of a respiratory infection, such as COVID-19, and you have a high temperature or do not feel well enough to go to work or carry out normal activities, you are advised to try to stay at home and avoid contact with other people.
What should I do if I am diagnosed with COVID-19?
Try to stay at home and avoid contact with other people. If you have a positive COVID-19 test result, it is very likely that you have COVID-19 even if you do not have any symptoms. You can pass on the infection to others, even if you have no symptoms.
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 the coronavirus disease spread through the air in rooms?
In poorly ventilated rooms the amount of virus in the air can build up, increasing the risk of spreading COVID-19, especially if there are lots of infected people in the room. The virus can also remain in the air after an infected person has left.
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.
What is asymptomatic transmission?
An asymptomatic laboratory-confirmed case is a person infected with COVID-19 who does not develop symptoms. Asymptomatic transmission refers to transmission of the virus from a person, who does not develop symptoms.
There are few reports of laboratory-confirmed cases who are truly asymptomatic, and to date, there has been no documented asymptomatic transmission. This does not exclude the possibility that it may occur. Asymptomatic cases have been reported as part of contact tracing efforts in some countries.
How long do I have to wait for my booster after having COVID-19?
If you have a COVID-19 positive result, when can you have a booster? You will still need the booster but you should wait at least 4 weeks from your COVID-19 infection.

Ronapreve is the first neutralising antibody medicine specifically designed to treat COVID-19 to be authorised by the Medicines and Healthcare products Regulatory Agency (MHRA) for use in the UK.
What is one way of preventing COVID-19 transmission?
Limit close contact with other people outside your household as much as possible. Meet outside and try and stay at least 2 metres apart from them
Can you contract the coronavirus disease by touching a surface?
Like the common cold, coronavirus infection usually occurs through close contact with a person with novel coronavirus via cough and sneezes or hand contact. A person can also catch the virus by touching contaminated surfaces if they do not wash their hands.
Can the coronavirus disease spread through food?
It is very unlikely that COVID-19 is transmitted through food. However, as a matter of good hygiene practice, anyone handling food should wash their hands often with soap and water for at least 20 seconds before doing so. Crockery and eating utensils should not be shared. Clean frequently touched surfaces regularly.
Is it safe to live in the same house as someone with COVID-19?
People who live in the same household as someone with COVID-19 are at the highest risk of becoming infected because they are most likely to have prolonged close contact. People who stayed overnight in the household of someone with COVID-19 while they were infectious are also at high risk.
How does fresh air help to prevent the spread of COVID-19?
Bringing fresh air into a room and removing older stale air that contains virus particles reduces the chance of spreading COVID-19. The more fresh air that is brought inside, the quicker any airborne virus will be removed from the room.
Can I have close contact with people if I'm wearing a mask during COVID-19?
While wearing a mask, you should still keep physical distance from others as much as possible. Wearing a mask does not mean you can have close contact with people.
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.
Can COVID-19 spread through water while swimming?
Fact: Water or swimming does not transmit the COVID-19 virus
The COVID-19 virus does not transmit through water while swimming. However, the virus spreads between people when someone has close contact with an infected person.
WHAT YOU CAN DO:
Avoid crowds and maintain at least a 1-metre distance from others, even when you are swimming or at swimming areas. Wear a mask when you’re not in the water and you can’t stay distant. Clean your hands frequently, cover a cough or sneeze with a tissue or bent elbow, and stay home if you’re unwell.
What are the long lasting fruits and vegetables I should buy for COVID-19 quarantine?
WHO recommends consuming a minimum of 400 g (i.e. 5 portions) of fruits and vegetables per day. Citrus fruits like oranges, clementines and grapefruit are good options, as well as bananas and apples, which can also be cut into smaller pieces and frozen for later consumption or to add to smoothies.
Root vegetables such as carrots, turnips and beets, as well as vegetables like cabbage, broccoli and cauliflower are relatively nonperishable. Garlic, ginger and onions are also great options to keep at home, as they can be used to add flavour to a variety of meals.
