What are foodborne viruses? Foodborne viruses are those that can be contracted by eating or drinking contaminated food or water. They can withstand extremes in temperature and humidity as well as hostile conditions like low pH (acidity). Because of this, they can survive infectively in food and water for much over a month. These viruses … Read more

The predominant clinical manifestation of mumps is parotitis-related salivary gland enlargement. This symptom is so distinctive that the disease was immediately distinguished from other pediatric illnesses that cause skin rashes. In the fifth century B.C., Hippocrates identified measles as a distinct disease. Additionally, he mentioned orchitis as a common complication of mumps. In some cases … Read more

Epstein-Barr Virus (EBV), also known as Human Herpesvirus 4, is a virus that belongs to the herpesvirus family. It is one of the most common viruses in humans and is estimated to infect over 90% of people worldwide at some point in their lives. EBV is primarily transmitted through contact with infected saliva, such as … Read more

Zika Virus (ZIKV) Characteristics of Zika Virus (ZIKV) Structure of Zika Virus Genome Structure of Zika Virus Zika Virus Replication Viruses cannot replicate until they infect and “reprogram” appropriate host cells to become virus-producing factories. The epidermis and dermis of the host skin contain fibroblast, keratinocytes, and immature dendritic cells where the Zika virus replicates. In … Read more
