Many countries are seeing a gradual decrease in coronavirus cases and deaths, allowing doctors and scientists to turn their attention to the longer-term impact of Covid-19.
The most common symptoms of the virus include fever, dry cough and a loss of smell, with most sufferers experiencing a mild form of these symptoms.
Most people will recover within a few days, but up to 5 percent of infections will require hospitalisation and further medical treatment.
Some people are also reporting persistent symptoms that last for months - even if they're only experiencing a relatively mild case.
