Ecology matters: "while drought decreases #mosquito abundances, it paradoxically increases #WNV infection (...) probably stems from reduced water availability, which concentrates mosquitoes and pathogen-amplifying bird hosts around limited water sources"

Great paper "Implications of successive blood feeding on Wolbachia-mediated dengue virus inhibition in Aedes aegypti mosquitoes", showing that successive feeding shortens #dengue EIP but #Wolbachia retains protective effects. doi.org/10.1038/s414...

Wondering what the potential of the #Qdenga #vaccine against #dengue infection and disease may be if delivered? This is a great paper to go to.

Great. Can we start sooner?

We have been exploring a bit whether #ClimateChange trends (1980-2019) in some Atlantic #archipelagos may have resulted in changes to climate-based #ecological suitability for #dengue virus - in short, yes; but with relevance only in tropical islands. We will put this and other results out ASAP.

Haven't used Xeeter for 7 months, and today I am purging my footprint. That is 2887 Xeets over the years. You can do the same using Luca Hammer's script.

This is Kiddo. A Portuguese Podengo found abandoned in my street in Lisbon 1y ago. She is now 2 and a happy dog. Podengo's closest relatives are Egyptian hunting dogs (from which they inherit the Jackal looks). This time of the year is when pets get most abandoned. As a society we can do better.

We - CLIMADE (climade.health) - participated in COP29 with a summary of our work (climate driven pathogens) and proposed recommendations for the near future.

Curious on the #ecological conditions associated with the recent emergence of #Oropouche in #Brazil ? We explore this in a new #preprint currently under review [1]. Huge team effort, with support of the CLIMADE consortium [2].

This is what we estimate to be the typical seasonality of environmental suitability for West Nile virus ocurrence in Portugal. We look at Portugal, 2 other EU countries and 5 Atlantic archipelagos. Results will be on preprint pretty soon. #WNV

The seminal hypothesis framework for this has been around for more than 25 years, with numerous following papers demonstrating it for viruses and bacteria. I recommend having a look at the paper from 1998.

Rapid Spatial Expansion Beyond the Amazon Basin: Oropouche Virus joins other main arboviruses in epidemic activity across the Americas - we x2 publicly available genomes, characterize recent recombination and spatial spread. #CLIMADE #OROV

North-south pathways, emerging variants, and high climate suitability characterize the recent spread of dengue virus serotypes 2 and 3 in the Dominican Republic.

In 2023 #Italy had the highest #dengue virus local activity to date. We integrate epidemiological, #genomic & climatic spatio-temporal data of the past eight years related to circulating viral lineages, geographic distribution, hotspots of reporting & the contribution of local #climate.
