In May 2023, the World Health Organisation declared an end to Covid-19 as a public health emergency. However, long Covid—in which symptoms persist for more than 12 weeks after disease onset—continues to be studied around the world for diagnosis and treatment.

The researchers, including those from the University of Brasília, Brazil, show that among the nearly 1.4 lakh people involved in the 18 studies, being overweight had a significant link with persistent depression, headache, memory problems and sleep disturbances.
