🦟 Health officials have identified the first locally acquired case of #malaria in Arkansas last week. The U.S. broke its 20-year streak of zero locally acquired malaria cases in 2023 after four states reported cases, including the first-ever in Arkansas. ualrpublicradio.org/local-regional…

New York's old rainfall record stood for 150 years until 2021, and has now been broken three times. Hot air holds more water vapor than cold; flooding follows fossil fuel combustion as night follows day.

@PMIgov In 1951, the CDC tallied a minimum of 14 locally acquired cases (see below from ajtmh.org/view/journals/…). If by eliminated we mean zero local transmission, as far as I can tell that did not occur until 1961 (cdc.gov/mmwr/preview/m…).

📢 #TriviaTuesday Q: What year was Malaria eliminated from the United States? Check back later to see if you’re correct!

After the malaria outbreak in Florida this summer, people are speculating about whether climate change will bring the disease back to the US. The short answer is probably not, but the story is a bit more complicated. My latest for @DiscoverMag discovermagazine.com/planet-earth/f…

Our new preprint, "The historical fingerprint and future impact of climate change on childhood malaria in Africa," unravels a 200-year story about one of the earliest and most controversial health impacts of climate change 🧵 medrxiv.org/content/10.110…

@mcwimberly It’s a great question- wonder if our @CDCgov domestic malaria friends have thoughts on why we haven’t seen (curiously the last year of this graph happened to be the last local case reported until now)? Importation keeps increasing (cdc.gov/mmwr/volumes/7…) so it seems surprising

This is some pretty important contextual information w/ respect to the recent report of local #malaria transmission in the United States. Is there a reason why we haven't seen any for the past 20 years? Or have we just not been paying enough attention?

That's an interesting observation. Thank You Justin. ~ Goes to show how malaria surveillance continues to be important even long after elimination (The United States was declared malaria-free by WHO in 1970: who.int/teams/global-m…) Even more importantly, it show how expensive and how complicated it can be to tackle these sporadic malaria incidences. As Filler et al states: "Although these locally acquired mosquito-transmitted outbreaks frequently involve only a limited number of infected persons, they frequently raise concerns in the community and require substantial public health resources. For example, as a result of the most recent local outbreak of eight malaria cases in Florida in 2003, reverse 911 telephone calls (a community notification system) were made to approximately 300,000 residents; insect repellent, postcards, flyers, and posters in multiple languages were distributed; public announcements were made through the media and to schools and homeless shelters; and notifications were sent to local hospitals and physicians to inform residents of that community. cdc.gov/mmwr/preview/m…"

@Fredros_Inc @NoorAbdisalan I'd argue that the last 20 years with no local transmission is more anomalous than the recent outbreak! Scott Filler published this back in 2006 showing local cases by year... we even had a cluster here in NYC back in 1993: cdc.gov/mmwr/preview/m…

My friend @NoorAbdisalan reminded me yesterday that Florida's climate has always been suitable for tropical diseases including malaria. ~ This suggests the recent cases of malaria there might not necessarily be a result of climate change. Moreover, such occasional local infections are not necessarily "black swans" in such areas. They are just very rare, but should be expected given all the global travel and the obvious receptivity (presence of competent vector species) in the area

If you worry about global warming & malaria reestablishing where you live, please tell your elected representatives to support malaria eradication. It would reduce your risk a little. …but if you’re scared, imagine living with malaria all the time. /1

🦟It’s here! Our @MalariaJournal paper shows that continuous #bednet distribution could provide higher, more consistent protection against #malaria, with 20% fewer nets than mass campaigns – as long as nets last ≥2.5 years rdcu.be/dfNdl. 🧵1/7

A first-of-its-kind study by @Cornell and CHAI in @ACSPublications shows that pharmaceutical companies could cut by nearly half their #CarbonFootprint if they optimized manufacturing processes and supply chain networks and used renewable energy sources. ow.ly/6R8350Ojle6

Today we officially launch OpenDengue- a global database of publicly accessible dengue case data opendengue.org (1/5)

Thanks! Base location is flexible-could be in any of the endemic countries where we work.

A great illustration, I think, of two critical concepts: 1) seeing mostly indigenous cases doesn’t negate the importance of importation for driving transmission; 2) efficient strategies will require coordination across connected catchments- going it alone won’t get the job done.

Thanks for the opportunity to offer some #WorldMalariaDay reflections on an exciting and challenging decade.

The evaluations by @lipangalala @SwissTPH across 3 high malaria-endemic contexts suggest that nearly two decades after Mills's commentary, essential routine systems remain insufficient to reliably provide life-saving malaria treatment to those most in need bmcmedicine.biomedcentral.com/articles/10.11…
