Artemis II is 10 days. Future Mars missions could last 2–3 years.
Understanding airborne transmission in microgravity is essential for crew safety.

Without gravity, virus-laden particles don't settle. They float indefinitely. Our modeling shows:
286× higher viral concentration in air vs Earth
~78% infection probability in 1 week (nearly 2× Earth)
HEPA filtration cuts airborne virus by 99.79%
Spaceflight suppresses immunity, potentially increasing viral shedding ~8-fold

Our new paper just accepted in The Journal of Infectious Diseases! 🎉
We tracked Plasmodium knowlesi in wild macaque faeces across 9 countries in Southeast & South Asia — 4,752 samples, 8.2% positivity.
First large-scale field evidence that faecal DNA surveillance can monitor zoonotic malaria without invasive animal handling.
A scalable, ethical approach that could integrate into wastewater & environmental monitoring systems for early warning of spillover risk.
Great multinational collaboration led by @dr_leshan 🦟🐒

Update on #mpox, a 🧵
In September, 42 countries reported 3135 confirmed #mpox cases and 12 deaths. Over 80% of the cases were in Africa, where 17 countries continue to experience active transmission.
Kenya and Liberia are showing upward trends in reported cases.
World Health Organization (WHO)@WHO
In September 2025, 42 countries reported a total of 3135 confirmed mpox cases, including 12 deaths. Local community transmission of clade Ib is expanding beyond Africa, and cases have been reported among men who have sex with men. WHO assesses the public health risk of mpox as low for the general population and moderate for men who have sex with men. Read more: bit.ly/4hHQZZ6

🧵 NEW PREPRINT: Our team has developed a machine learning model to predict leptospirosis outbreaks in Thailand by identifying key environmental and socioeconomic risk factors. This could lead to better early warning systems for this neglected tropical disease.
