People in China, which has the world’s largest population of sufferers of the virus, are dying at rates four times higher than the international average.
A study published in the Lancet medical journal said that about 30% of those who contracted the disease were women.
The study found that women who did not take anti-coagulant drugs had a five-fold increased risk of death than those who took them, and that those who died of COVID were more likely to have been male.
Researchers also found that those in rural areas, where women make up a disproportionate share of the population, had a higher risk of COVI than those in cities.
A report by the World Health Organization last month also found higher rates of COVE in China than elsewhere in the world.
Despite the higher death toll, China is still relatively low on COVID levels.
According to WHO data, the total number of COV-19 cases in China has been declining since last year, when the virus hit a peak of about 11,000 a day.
China reported only 13 deaths in December, compared with about 1,200 in 2016.
China also has one of the highest rates of infection in the Western Hemisphere, but the numbers are still very low compared with other parts of the world, including the US.
