HIV can be transmitted from an infected mother to the neonate in three circumstances: across the placenta during pregnancy (in utero), at birth due to fetal contact with infected maternal genital secretions and blood, or postnatally through the breast milk. [8] This type of viral transmission is also known of as vertical transmission.
About 20% of COVID-19 cases that pass through the intensive care unit (ICU) have chronic neurologic symptoms (beyond loss of smell and taste). [1] Of the patients that had an MRI , 44% had findings upon MRI, such as a FLAIR signal (fluid-attenuated inversion recovery signal), leptomeningeal spaces and stroke.
The placenta does not block maternal IgG antibodies, which thereby may pass through the human placenta, providing immune protection to the fetus against infectious diseases. One model for the induction of tolerance during the very early stages of pregnancy is the eutherian fetoembryonic defense system (eu-FEDS) hypothesis. [ 10 ]
Children whose mothers had coronavirus infections during pregnancy were more likely to be diagnosed with neurodevelopmental problems, a study finds. Coronavirus infection during pregnancy linked ...
Zika fever, caused by Zika virus, can cause microcephaly and other brain defects in the child. [11] COVID-19 in pregnancy is associated with an increased risk of stillbirth with an odds ratio of approximately 2. [12] Hepatitis B may also be classified as a vertically transmitted infection. The hepatitis B virus is
COVID-19 often shares a lot of the same symptoms as influenza, including stuffy or runny nose, sore throat, cough, muscle aches, fatigue and fever or chills. But unlike the flu, COVID symptoms can ...
HIV-associated neurocognitive disorders (HAND) are neurological disorders associated with HIV infection and AIDS.It is a syndrome of progressive deterioration of memory, cognition, behavior, and motor function in HIV-infected individuals during the late stages of the disease, when immunodeficiency is severe.

The rapid development, though, of mRNA vaccines to deal with the COVID-19 pandemic may provide a new path forward. [citation needed] Like SARS-CoV-2, the virus that causes COVID-19, HIV has a spike protein. In retroviruses like HIV, the spike protein is formed by two proteins expressed by the Env gene.
