In a new study from CDC, researchers found the prevalence of certain symptoms and conditions is increased at 31 to 150 days following testing among individuals who test positive for COVID-19.

They analyzed aggregated electronic health record data for 338,024 persons aged younger than 20 years and 1,790,886 persons aged 20 years or older who were tested for SARS-CoV-2 from March to December 2020.

The new diagnoses of select symptoms and conditions were examined between 31 and 150 days after testing.

The team found overall, 168,701 persons aged 20 years or older and 26,665 aged younger than 20 years tested positive for SARS-CoV-2.

Among hospitalized patients, shortness of breath was more common for persons with a positive versus negative test result.

Among non-hospitalized patients aged 20 years or older, shortness of breath was also more common for those with a positive versus negative test result.

Among hospitalized patients aged 20 years or older, those with a positive versus negative result had an increased prevalence of new fatigue and type 2 diabetes.

These findings highlight the need for health care professionals and patients to monitor for the development of new symptoms and conditions beyond the first month after SARS-CoV-2 infection, particularly for individuals who required hospitalization for acute COVID-19.
