How long is the incubation period for COVID-19?

The time taken by the symptoms to first appear on an infected individual. The incubation time for COVID-19 ranges from 1-14 days, most commonly being around 5 days.

What are the primary symptoms of COVID-19?

Some of the primary symptoms to look for in a Covid 19 infected person are fever, dizziness, breathlessness, headache, dry cough ( eventually result in phlegm) and in a few cases loss in smell and taste. A few cases have also reported diarrhoea and fatigue.

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 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.

What is a post COVID-19 condition (long COVID)?

How is post COVID-19 condition defined? Post COVID-19 condition is defined as the illness that occurs in people who have a history of probable or confirmed SARS-CoV-2 infection; usually within three months from the onset of COVID-19, with symptoms and effects that last for at least two months.

Can masks prevent the transmission of COVID-19?

See full answer

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!
Make wearing a mask a normal part of being around other people. The appropriate use, storage and cleaning or disposal of masks are essential to make them as effective as possible.

What are the organs most affected by COVID‐19?

The lungs are the organs most affected by COVID‐19

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 some ways to maintain a healthy diet during the COVID-19 pandemic?

See full answer

Eat a variety of foods:

Every day, eat a combination of different foods including whole grains such as wheat, maize and rice, legumes like lentils and beans, fruit and vegetables and some foods from animal sources (e.g. meat, fish, eggs and milk).

Eat plenty of fruit and vegetables:

● Eat fresh fruit and vegetables that are in season.
● Eat a variety of fruit and vegetables.

Keep salt intake to less than 5 g per day (approximately 1 teaspoon):

● Use less salt during cooking and preparing food and use iodized salt.
● Check the labels on food and choose products with lower sodium content.
● Limit processed and prepackaged foods, which can be full of hidden sodium.
● Remove the salt shaker from the table, and instead use fresh or dried herbs and spices for added flavour.

What are some of the ways by which COVID-19 is transmitted?

COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors.

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.

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.

What does it mean to be an asymptomatic carrier of COVID-19?

These are people who do not show any signs or symptoms of the disease on contracting it for the entire duration of the incubation period. This can last for around 14 days. As a result, they end up transmitting the virus to a lot of people. This fuels the pandemic in a rapid and dangerous manner.

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.

What is a silent carrier in the context of COVID-19?

There is recent evidence that COVID-19 can spread through silent carriers. These silent carriers or spreaders are people who are infected with coronavirus but show little or no symptoms of the disease. As a result, these people carry on with their daily lives, meeting family and friends, going to work, and spreading the disease without their own knowledge.
