If someone is suffering from long COVID, then there is no way to know how long it will take for him/her to recover from the ailment.
US CDC had earlier pointed out that people who contract mild COVID recover from it in 1 to 2 weeks, while for severe COVID patients, symptoms may continue for 6 weeks or more.
However, a Lancet Respiratory Medicine's recent study showed at least half of the people hospitalized due to COVID suffer from one or more symptoms even two years after the infection.
The study that was led by doctors at the China–Japan Friendship Hospital in Beijing followed 1,192 people hospitalized with Covid at Wuhan’s Jin Yin-tan hospital in early 2020, checking in with them six months.
