Nearly one in five American adults who reported having Covid-19 in the past is still having symptoms of long Covid, according to survey data collected in the first two weeks of June, US health officials said on Wednesday.

Overall, one in 13 adults in the United States has long Covid symptoms lasting for three months or more after first contracting the disease, which they did not have before the infection, the data showed.

The data was collected from June 1-13 by the US Census Bureau and analysed by the US Centers for Disease Control and Prevention (CDC).

Long Covid symptoms range from fatigue, rapid heartbeat, shortness of breath, cognitive difficulties, chronic pain, sensory abnormalities and muscle weakness. They can be debilitating and last for weeks or months after recovery from the initial infection.

The CDC analysis also found that younger adults were more likely to have persistent symptoms than older adults.

Women were also more likely to have long Covid than men, according to the study, with 9.4 percent of US adult women reporting long Covid symptoms compared to 5.5 percent of men.

The survey found nearly nine percent of Hispanic adults have long Covid, higher than non-Hispanic white and black adults, and more than twice the percentage of non-Hispanic Asian adults.

There were also differences based on US states, with Kentucky and Alabama reporting the highest percentage of adults with long Covid symptoms, while Hawaii, Maryland and Virginia reported the lowest, according to the survey.
