Persistent systemic infection for months
In people who died of Covid, the virus was found in various tissues throughout the body, including the brain, as late as 230 days following the symptom onset of an acute infection. In some patients, the virus can cause systemic infection and persist in the body for months. Among the other affected organs and tissues are the heart and blood vessels, lungs and the respiratory system, muscles, skin, thyroid, esophagus, spleen, appendix, adrenal glands, ovaries, testes, and womb.

Unexplained stillbirths
In a study of 170 women who delivered after a confirmed Covid infection, 50% had placental abnormalities. These were found to be associated with poor pregnancy outcomes, including a significantly higher number of stillbirths (17% vs. 4%) that could not be explained by other risk factors. Babies who survived had lower Apgar scores (a basic measure of the baby's health at birth).

Immune development in babies
Babies were born with reservoirs of SARS-CoV-2 in their intestines months after the mother's infection. The presence of SARS-CoV-2 in a baby's gut may significantly impact the development of the immune system both before and after birth, with the potential for babies to suffer from higher susceptibility to disease and other dangerous outcomes.
