Insights

A new database maps Mayaro Virus (MAYV) occurrences across the Americas from 1954-2022. This resource aids in understanding MAYV spread and identifying surveillance gaps for this emerging health threat.

Area of Science:

  • Epidemiology
  • Arbovirology
  • Public Health

Background:

  • Mayaro Virus (MAYV) is an emerging arbovirus causing significant febrile illness and arthralgia in the Americas.
  • Understanding the geographic distribution of MAYV is crucial for risk assessment and public health interventions.

Purpose of the Study:

  • To develop a comprehensive, georeferenced database of Mayaro Virus occurrence.
  • To consolidate and grade evidence of MAYV presence in humans, animals, and arthropods.

Main Methods:

  • Systematic literature review and analysis of unpublished reports for MAYV occurrence data.
  • Georeferencing of identified MAYV occurrences, creating a point and polygon database.
  • Implementation of a quality grading system to assess the reliability of included studies.

Main Results:

  • A georeferenced database containing 262 confirmed MAYV occurrences from 1954 to 2022 was compiled.
  • Data includes occurrences in humans, non-human animals, and arthropods across the Americas.
  • The database is evidence-graded, providing a quality assessment for each data point.

Conclusions:

  • The developed database provides a valuable resource for understanding MAYV epidemiology and geographic spread.
  • This tool can support risk assessment, epidemiological modeling, and the identification of critical surveillance gaps.
  • The database is designed for future updates, ensuring its continued relevance in monitoring MAYV.

Retroviruses02:33

Retroviruses

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’...

Viruses with RNA Genomes01:29

Viruses with RNA Genomes

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

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...

Viruses of Archaea

Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Introduction to Virus01:28

Introduction to Virus

Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...
