Cytomegalovirus Disease01:27

Cytomegalovirus Disease

5
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Viruses with RNA Genomes01:29

Viruses with RNA Genomes

1.2K
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

50.4K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Retroviruses

15.6K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Arboviral Encephalitis01:25

Arboviral Encephalitis

1
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Subviral Agents01:29

Subviral Agents

721
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

    Summary

    Cytomegalovirus (CMV) infection during pregnancy can harm newborns. Raising awareness is crucial as CMV is a leading preventable cause of childhood hearing loss.

    Area of Science:

    • Virology
    • Public Health
    • Pediatrics

    Background:

    • Cytomegalovirus (CMV) is a common herpesvirus infection.
    • Congenital CMV infection can lead to severe health issues in newborns.
    • CMV is a significant, yet often overlooked, public health concern.

    Purpose of the Study:

    • To increase awareness of Cytomegalovirus (CMV) infection.
    • To highlight CMV as a preventable cause of childhood hearing loss.
    • To inform the public about the prevalence and impact of CMV.

    Main Methods:

    • This article is based on the experiences and advocacy of a volunteer charity.
    • Information is disseminated through awareness campaigns.
    • The focus is on public education and advocacy.

    Main Results:

    • CMV infection is more prevalent than several other well-known conditions like Down's syndrome, listeria, and toxoplasmosis.
    • CMV is identified as the primary preventable cause of hearing loss in children.
    • There is a need for greater public understanding and preventative measures.

    Conclusions:

    • Increased awareness and public education are vital to prevent congenital CMV infections.
    • Early detection and intervention strategies are necessary to mitigate the effects of CMV.
    • Community-led initiatives play a key role in addressing the public health challenge posed by CMV.
