Research updates, September 15
Repeat SARS-C0V-2 infections were linked to a higher odds of new health conditions, according to a new study in the Canada Communicable Disease Report. The post Research updates, September 15 first appeared on The Sick Times .
Centers for Disease Control and Prevention's Public Health Image Library released a study on September 15, 2026 revealing that repeated SARS-CoV-2 infections were associated with a higher likelihood of developing new health conditions. In the research, which analyzed data from 9,000 individuals who responded to a survey conducted between 2020 and 2023, those who experienced more than two SARS-CoV-2 infections were found to have a 76% increased risk of receiving a new diagnosis compared to those who had not reported any infections.
The survey covered a wide array of diagnoses, encompassing respiratory, cardiovascular, neurological, and musculoskeletal conditions. However, the researchers cautioned that the study could not definitively prove a causal link between SARS-CoV-2 infection and the new conditions due to the limitations of the research. The National Institute of Allergies and Infectious Diseases (NIAID) has included long COVID, myalgic encephalomyelitis, and post-treatment Lyme disease as priorities in its 2026-2030 Strategic Plan.
The institute aims to focus on identifying risk factors and underlying mechanisms behind these long-term conditions. NIAID remains committed to supporting research to develop person-centered prevention and treatment strategies aimed at improving the quality of life for those impacted by long-term conditions following the resolution of an infection. However, it remains unclear how NIAID intends to finance future research for these diseases.
