What is COVID-19?
COVID-19 is a disease caused by the coronavirus SARS-CoV-2. It can affect your lungs, airways and other organs.
Coronaviruses are from a large family of viruses that cause illnesses like the common cold.
SARS-CoV-2 was first recognised in China. It's still unclear how the virus came to infect humans. The disease spread to other countries, with the World Health Organization (WHO) declaring a pandemic on 11 March 2020.
There have been genetic mutations (changes) to the virus over time. Some of these mutations, such as the Omicron variant, can spread more easily than the original virus.
How easy is it to catch and spread COVID-19?
COVID-19 is an airborne illness that spreads from person to person. When an infected person breathes, speaks, coughs, sneezes or sings, they may spread particles containing the virus. These particles range in size. Some particles can remain on surfaces or airborne for minutes to hours.
The risk of catching COVID-19 is higher:
- in enclosed spaces that do not have good airflow
- in crowded places
- in close-contact settings, such as close-range conversations
How can I reduce the risk of getting COVID-19?
What are the symptoms of COVID-19?
If tamariki (children) catch COVID-19, they often only have mild symptoms. Some tamariki may have no symptoms.
Common symptoms of COVID-19 are similar to cold and flu symptoms.
They can include:
- sneezing and runny nose
- tiredness, feeling generally unwell
- loss of taste or smell
- sore, scratchy throat
- shortness of breath
Symptoms of COVID-19 may also include:
- diarrhoea, nausea, vomiting, particularly in babies and young tamariki
- tummy pain
- muscle aches
- wheezing and croup-like illness
These symptoms can happen with other illnesses and do not necessarily mean you or your child have COVID-19.
Shortness of breath is a sign of possible pneumonia - your child needs to see a doctor immediately.
How long does it take for symptoms to appear?
People who get COVID-19 symptoms are likely to get them within 3 days of first being infected. But it could take up to 8 days after infection. People may have COVID-19 without any symptoms.
Some people with COVID-19 can pass it on to others 1 or 2 days before showing symptoms.
