Insights

Mayaro virus, an emerging arbovirus, caused 17 cases in French Guiana between 2003-2019, presenting symptoms similar to Chikungunya. Awareness is crucial as imported cases pose a risk in Europe.

Area of Science:

  • Medical Entomology
  • Tropical Medicine
  • Virology

Background:

  • Mayaro virus (MAYV) is an emerging arbovirus prevalent in tropical regions.
  • Latin America faces recurring arbovirus epidemics, including Dengue, Chikungunya, and Zika.
  • MAYV, an alphavirus, presents clinically similar to Chikungunya and is currently forest-mosquito-borne.

Purpose of the Study:

  • To investigate the demographic and clinical characteristics of Mayaro virus disease in French Guiana.
  • To raise physician awareness of Mayaro virus due to its potential for widespread transmission and imported cases.

Main Methods:

  • Retrospective study of human cases in French Guiana from 2003 to 2019.
  • Analysis of clinical and biological data of identified Mayaro virus infections.

Main Results:

  • 17 human Mayaro virus cases were identified between 2003 and 2019.
  • Clinical presentation included fever and arthralgia, resembling Chikungunya.
  • One case of acute meningoencephalitis and four cases of persistent arthralgia were noted.

Conclusions:

  • Mayaro virus is an endemic arbovirus in French Guiana with significant clinical manifestations.
  • Physicians must be aware of Mayaro virus, especially considering its potential for transmission by Aedes aegypti mosquitoes and documented imported cases in Europe.

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

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 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...

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
