Human cytomegalovirus (HCMV) is a member of which virus family?

1. Orthomyxoviridae

2. Flavivirus

3. Herpes virus

4. Paramyxovirus

The correct answer is: Herpes virus

Human cytomegalovirus (HCMV) is classified as a member of the Herpesvirus family. This classification is due to several characteristics that are typical of herpesviruses, including their structure, replication cycle, and the ability to establish latent infections in the host. Herpesviruses, which include other well-known viruses such as herpes simplex virus and varicella-zoster virus, are known for their ability to remain dormant in the body and reactivate later, which is a key feature of HCMV as well. In the case of HCMV, it is often associated with opportunistic infections, particularly in immunocompromised individuals, such as those with HIV/AIDS or those receiving organ transplants. Its pervasive presence and latency highlight its significance in clinical settings, making understanding its classification crucial for midwives and healthcare providers. The other virus families listed, such as Orthomyxoviridae, Flavivirus, and Paramyxovirus, include viruses that cause different diseases and have distinct pathogenic mechanisms and structures, which set them apart from the herpesviruses. Understanding these distinctions is essential for effective diagnosis and treatment planning.
