Emerging zoonotic viruses in birds, bats and pigs. #influenza #surveillance, #metagenomics, #sequencing, #pathogenesis, #virus ecology/evolution. Opinion = own.

1/ Excited to share our new paper in PLOS Neglected Tropical Diseases:

Discovery of a novel coltivirus in a newly identified bat bug species in Cambodia.

6/ This work reinforces the value of One Health surveillance looking beyond vertebrate hosts alone and includes the arthropods associated with them.

Very grateful to all co-authors and collaborators across virology, entomology, field ecology, metagenomics, and virus discovery.

Cambodia confirms 2nd human #H5N1 case of 2026 in a 45-year-old woman from Banteay Meanchey province. Patient hospitalized and under treatment.

2026: 2 cases, 0 deaths
Since 2023: 36 cases, 15 deaths (CFR 41.7%)
Since 2004: 92 cases, 52 deaths (CFR 56.5%)

First human #H5N1 case of 2026 in #Cambodia: a 30-year-old man from Kampot province. Sequencing, virus isolation & animal investigations ongoing. Dead chicken at home before onset. Patient has since recovered.

@MarionKoopmans Dank Marion!

In our recent @NatureComms study, we compared traditional #poultry swabs with environmental #metagenomics, sampling #air, cage surfaces, carcass wash water, and drinking water in two Cambodian live bird markets.

@RealVision @RaoulGMI @BittelJulien $BTC: $210k

Fed cuts = more liquidity + weaker dollar → rocket fuel. Govt reopening adds a money-market pulse.
AI boom = deflationary productivity shock → faster easing + capital inflow to risk assets. Add accelerating crypto adoption → BTC enters its late-cycle banana zone.

Come find me today at the @AmerSocVirol in Montreal, Canada, where I will present about the emergence of a novel reassortant clade 2.3.2.1c/e virus associated with human cases in Cambodia!

In May 2025, The Telegraph joined our field mission on virus surveillance work in #Cambodia, where we used novel, non-invasive techniques like air sampling in live bird markets and bat caves, paired with field-deployable tools, to detect #emergingviruses at the source.

Cambodia has confirmed its 9th and 10th human cases of H5N1 bird flu this year. 6 of these cases occurred in June alone. Sadly, 6 people have died in 2025. #H5N1 #BirdFlu #Cambodia #Influenza
