Abstract:
Mayaro (MAYV) is a neglected arbovirus from the tropical Americas. Here, we report the complete genome of an MAYV isolate from a patient returning from the Amazon basin and complaining of arthralgia, high fever, and headache, who was attended at an emergency service of São José do Rio Preto, São Paulo state, Brazil.
Insights
Mayaro virus (MAYV), a tropical arbovirus, was identified in a Brazilian patient presenting with fever and joint pain. This study details the complete genome sequence of this MAYV isolate, contributing to understanding its spread.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Mayaro virus (MAYV) is a significant arbovirus prevalent in the tropical Americas.
- MAYV infections can cause symptoms such as arthralgia, fever, and headache.
- The geographic distribution and genetic diversity of MAYV are crucial for public health surveillance.
Purpose of the Study:
- To report the complete genome sequence of a Mayaro virus isolate.
- To characterize a MAYV strain detected in a patient returning from the Amazon basin.
- To contribute to the genomic surveillance of arboviruses in Brazil.
Main Methods:
- Viral RNA extraction and sequencing.
- Whole-genome sequencing of the MAYV isolate.
- Bioinformatic analysis of the viral genome.
Main Results:
- The complete genome sequence of a Mayaro virus isolate was successfully obtained.
- The isolate was identified in a patient presenting with classic MAYV symptoms.
- The patient had recently traveled to the Amazon basin, indicating potential geographic spread.
Conclusions:
- The genomic data provides valuable insights into the MAYV strain circulating in the region.
- This finding highlights the importance of diagnostic capabilities for arboviruses in non-endemic areas.
- Continued genomic surveillance is essential for monitoring arbovirus emergence and transmission patterns.
