CLOSING SOON: Postdoc (Gainesville, USA) Study dynamics of arbovirus transmission in the context of a US NIH funded cluster-randomized trial in Brazil with @datcummings @uf_idd @MHitchingsEpi at @UF_EPI @UFPHHP @UF_CLAS More details:

Individual, Household and Community Drivers of Dengue Virus Infection Risk in Kamphaeng Phet Province, Thailand ✅ Just Accepted 🔗 https://t.co/anQxwtuP5S by @PDGCambridge, @gab_rdsantos, et al.

We showed that shift in #demography is the key driver of 4 #decades of rising age of #DHF in #Thailand (8y->24y). Opportunity to make long-term #projections of #dengue based on demography elsewhere. https://t.co/2W5hnblztA @PNASNews @uf_idd @PDGCambridge

Mesmo quem teve covid deve se vacinar. Essa é uma das evidências mais robustas e generalizáveis que dá suporte a isso, resultado de uma colaboração entre muitos pesquisadores e pesquisadoras e instituições. Ainda em revisão. Vacine-se

Em uma colaboração entre os grupos VEBRA e VIGIVAC, nós fizemos um estudo caso-controle do tipo teste-negativo no Brasil. Selecionamos indivíduos confirmados por PCR ou Antigeno, adultos, e avaliamos a efetividade das 4 vacinas usadas no Brasil. Vale a pena ler os métodos,

Já tive COVID, devo me vacinar? Sim, sem dúvida. Como já dizíamos, agora com dados. Mostramos (preprint) que o ganho em proteção é muito grande. Para hospitalizações/óbito, após 2a dose: ➡️ 89.7% Pfizer ➡️ 89.9% AstraZeneca ➡️ 81.3% CoronaVac Vacine-se https://t.co/Gzcb3cjirX

New research by @UF_CLAS and EPI biologist @datcummings shows that as populations of people gain immunity to dengue, it drives evolutionary pressures that select for viral evolution—and newly susceptible hosts. https://t.co/WqZrDDWZQY @UFNews @UFExplore

May reflect evasion of heterotypic immunity but lots of work to do to understand selective pressures that could give rise to this pattern. With @hsalje Steve Whitehead @wrair Ana Coello @HuangAngkanaT @ufidd and others. 2/2

New work led by @LeahKatzelnick characterizing antigenic evolution of dengue viruses over 20 years in Thailand https://t.co/YMgHe7hFXH We found that dengue viruses became more antigenically distant from each other over time. 1/2

Today we hit 750,000 Americans lost to COVID19. We’re on trajectory to hit 800,0000 by year’s end. Those last 100,000+ maybe even 200,000 died unnecessarily because vaccines were widely available. They chose not to get vaccinated, sometimes even defiant. They died by antiscience

Can mosquitoes that harbor an infection-blocking bacteria help break the transmission cycle of certain viral diseases to people? A clinical trial in Brazil aims to find out: https://t.co/NTuxcWNXZ3 Research by @datcummings and @MHitchingsEpi of @UF_CLAS @UFPHHP @UFMedicine

Last minute costume change this year: I’m going as an academic exercising their free speech. Very scary to some folks, apparently

Vaccination with CoronaVac was associated with a reduction in symptomatic covid-19, hospital admissions, and deaths in adults aged ≥70 years, finds new research. Vaccine protection was low until completion of the two dose regimen:

Saiu o segundo artigo público do grupo VEBRA COVID-19. Agradeço imensamente a parceira com o @otavio_ranzani e @MHitchingsEpi e todos os demais autores. Pessoas extraordinários. Previlégio poder discutir ciência com vocês. https://t.co/vAEtjyhjGc

At this point, you are either vaccinated or you are going to catch Delta. And whether you are young adult or old, when you catch Delta unvaccinated, you will have the highest chance of being hospitalized compared to almost any disease you have caught in your life.

Our work about individual NPI policies’ effects on COVID-19 spread in the US counties is now out @NatureComms. We found, earlier in the pandemic, multiple interventions were needed to bring Rt below 1. Relaxing some NPIs needs counterbalanced by others.1/3

In my latest @TheAtlantic, I reflect on the year of the racial pandemic within the viral one. In sum: People of color were infected, hospitalized, impoverished, and killed at the highest rates, while receiving the fewest medical + economic protections. 1/4 https://t.co/mJocUYTWtS
