Exposure to environmental immunotoxicants may worsen outcome of SARS-CoV-2 infection
News
2 Nov 2020 | News Medical Life Sciences
Increased plasma PFBA levels were associated with more severe COVID-19 prognosis, even after adjustment for comorbidities, sex, age, origin, sampling time, and location. Although PFBA levels in plasma were lower than most PFAS studied, PBFA accumulates in the lungs, and hence it is suspected that PBFA exposure may contribute to the severity of disease.
