What are variants of SARS-COV-2, the virus that causes COVID-19?

# data[].attributes.body
It is normal for viruses to change and evolve as they spread between people over time. When these changes become significantly different from the original virus, they are known as “variants.” To identify variants, scientists map the genetic material of viruses (known as sequencing) and then look for differences between them to see if they have changed.

Since the SARS-CoV-2 virus, the virus that causes COVID-19, has been spreading globally, variants have emerged and been identified in many countries around the world.

COVID-19 affects different people in different ways. Most infected people will develop mild to moderate illness and recover without hospitalization.

Most common symptoms:

fever

cough

tiredness

loss of taste or smell.

Less common symptoms:

sore throat

headache

aches and pains

diarrhoea

a rash on skin, or discolouration of fingers or toes

red or irritated eyes.

Serious symptoms:

difficulty breathing or shortness of breath

loss of speech or mobility, or confusion

chest pain.

Seek immediate medical attention if you have serious symptoms.  Always call before visiting your doctor or health facility.

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.

What is the difference between a variant of interest and a variant of concern?

What is the difference between a variant of interest and a variant of concern?

# data[].attributes.body
A variant is considered a variant of interest if it has mutations that are suspected or known to cause significant changes, and is circulating widely (e.g., known to cause many clusters of infected people, or found in many countries). There are many variants of interest that WHO is continuing to monitor in case they become variants of concern.

A variant of interest becomes a variant of concern if it is known to spread more easily, cause more severe disease, escape the body’s immune response, change clinical presentation, or decrease effectiveness of known tools – such as public health measures, diagnostics, treatments and vaccines.

To protect yourself and others from COVID-19 variants:

Keep a distance of at least 1 meter from others

Wear a well-fitted mask over your mouth and nose

Open windows

Cough or sneeze into a bent elbow or tissue

Clean your hands frequently

Get vaccinated, as soon as it is your turn
