Women are more than twice as likely as men to suffer from long Covid, according to the largest study of the condition to date, which found a history of autoimmune disease or depression also increased the likelihood of experiencing symptoms.
The study by genetic testing company 23andMe surveyed more than 100,000 people who had Covid-19, about a quarter of whom reported having experienced long Covid — where symptoms such as breathing problems, fatigue and brain fog last for more than 12 weeks. Some 7,000 of these had been formally diagnosed.
Long Covid threatens to be a new public health crisis, keeping employees off work and adding to the burden on overstretched healthcare systems even after the most acute phase of Covid-19 has passed.
