[3] cCMV is caused when a mother is infected with CMV in pregnancy and passes it to her unborn baby. [1] The risk of severe disease is greatest if the mother is infected in early pregnancy; most have no symptoms. [2]
A vertically transmitted infection is an infection caused by pathogenic bacteria or viruses that use mother-to-child transmission, that is, transmission directly from the mother to an embryo, fetus, or baby during pregnancy or childbirth. It can occur when the mother has a pre-existing disease or becomes infected during pregnancy. Nutritional ...
Transmission of the molluscum contagiosum virus can occur many different ways including direct skin contact (e.g., contact sports or sexual activity), contact with an infected surface , or autoinoculation (self-infection) by scratching or picking molluscum lesions and then touching other parts of the skin not previously affected by the virus.

A significant difference between the genomes of mycoviruses to other viruses is the absence of genes for ‘cell-to-cell movement’ proteins. It is therefore assumed that mycoviruses only move intercellularly during cell division (e.g. sporogenesis) or via hyphal fusion.
For instance, people with severe cases of viral pneumonia – caused by viruses like the flu, RSV or SARS-CoV-2 – also often end up with a bacterial infection in the lungs or sinuses.
[1] [7] Systemic fungal infections are more serious and include cryptococcosis, histoplasmosis, pneumocystis pneumonia, aspergillosis and mucormycosis. [3] Signs and symptoms range widely. [3] There is usually a rash with superficial infection. [2] Fungal infection within the skin or under the skin may present with a lump and skin changes. [3]
Zika virus is an arthropod-borne virus transmitted by mosquitos, and infection during pregnancy can lead to severe congenital abnormalities in a newborn. Congenital infection can lead to fetal growth restriction and CNS abnormalities, including microcephaly , ventriculomegaly and intracranial calcifications.
Here is what parents need to know about the simultaneous respiratory viruses: Telling the difference between RSV, flu and COVID-19. At the onset of a virus, it’s very difficult to tell the ...
