About eight months have passed after declaring Coronavirus disease-2019 (COVID- 19) pandemic by the World Health Organization (WHO) on 11th March 2020, which is caused by SARS-CoV-2 virus first detected in Wuhan province of China in 31 December, 2019.

According to the World Health Organization, about 80% of infections are mild or asymptomatic, 15% result in moderate to severe symptoms (requiring oxygen) and about 5% are critical infections, which require ventilation.

We know a lot about the symptoms of COVID-19, but relatively little about what happens after someone recovers. Much is still unknown about how COVID-19 will affect people over time. There’s still much to be learned from those who have recovered from COVID-19.
