Arbovirus-host interactions
Reposted by Rafael Kroon Campos
Why surveillance is important? 4 years ago we predicted a CHIKV outbreak by detecting its silent circulation (lnkd.in/gx7-4ZeQ). Today, the team @mauriciolnogueira.bsky.social provided a genomic and clinical time map of the massive CHIKV outbreak of 2024 in the area. #FAMERP #SBV #ASTMH #UTMB #ACAV

This paper explores how variation in mosquito diversity, feeding behavior, vector competence, seasonality, and vector-pathogen interactions shape the transmission, persistence, and evolution of human malaria!
Frontiers | Mosquito vector diversity and malaria transmission
Malaria is the most important parasitic disease in the world, killing over half a million people a year. Globally, we have made gains toward eliminating this...

Our study exploring the evolutionary mechanism of alphavirus opal codon retention is now online! www.science.org/doi/10.1126/...
A conserved opal termination codon optimizes a temperature-dependent trade-off between protein production and processing in alphaviruses
Alphaviruses optimize viral polymerase production and polyprotein processing at distinct temperatures via a premature stop codon.

RNA: I made and ruled this world for eons before your precious proteins even conceived of a peptide bond
AlphaFold’s highly accurate structural models transformed protein biology. Nature reports on the efforts to create a similar system for RNA and why it’s a tougher nut to crack. #RNAsky 🧪
RNA function follows form – why is it so hard to predict?

Boom. Accepted for publication in Nature Communications. This paper has been a journey, but it is done. Here, we explore the use of constant temperature experiments to predict the thermal suitability for malaria transmission in a diurnally fluctuating environment.

Mean daily temperatures can predict the thermal limits of malaria transmission better than rate summation
Temperature shapes the distribution, seasonality, and magnitude of mosquito-borne disease outbreaks. Mechanistic models predicting transmission often use mosquito and pathogen thermal responses from c...

We detected yellow fever virus in Haemagogus mosquitoes collected in 2022 in an Amazon rainforest bordering Manaus, Brazil. The viral genome sequence occupied a basal position within the South American I genotype 1E lineage.

Vaccines work! As measles cases have recently been reported in Alaska, Georgia, New York, Rhode Island and Texas, it's important to remember that prior to the introduction of the measles vaccine in 1963, measles killed 400-500 people and resulted in ~48,000 hospitalizations per year.
