RISING THREAT — Covid-19 may not dominate the headlines like it once did, but infectious disease news isn’t going anywhere. The CDC is warning doctors to be on guard for malaria after at least five locally acquired cases, in Florida and Texas, were identified for the first time in decades. Last week, European health officials announced a sizable increase in the number of locally acquired cases of dengue in the past year. And those announcements may be just the beginning. Climate change and increasing connections worldwide are likely the main drivers of rising disease threats across the board, Syra Madad, an epidemiologist and biosecurity expert, told Pulse. Some have theorized that malaria and dengue — both spread through mosquitoes — being contracted in new places is connected with the changing climate, too. Shifting temperatures and rain patterns mean mosquitoes stay in some places weeks longer than they did decades ago, leading to stronger breeding seasons. “For those of us that are in this field,” Madad said of the increasing threats, “this is something that is bound to happen.” The U.S. eliminated malaria in the late 1940s, but the mosquito that can transmit it remained, said Patrick Kachur, a professor at Columbia University Medical Center, who worked on malaria and global health at the CDC for most of his career. The threat to individuals from the new malaria reports is relatively low, Madad said. But that doesn’t discount its significance at a population level. “It doesn’t take a lot for something low risk to go to something that is high risk,” she said. Policymakers feel the pressure. From Covid to mpox, malaria to dengue, headlines about new infectious disease risks remind lawmakers and administration officials that the need for health security plans will go beyond the pandemic. Dyann F. Wirth, an infectious disease professor at the Harvard T.H. Chan School of Public Health, said the U.S. needs to ensure that its surveillance systems pick up people who have malaria, which people are typically not tested for unless they say they have traveled abroad. “It's important to remember that untreated malaria can be fatal very rapidly: The parasite replicates very rapidly in the human host,” she said. “So, it's important also that the diagnostic capabilities in American hospitals and clinical practice remain well tuned, because if you miss a malaria case, it could have a serious consequence for the patient, not to mention for transmission,” she added. WELCOME TO THURSDAY PULSE, where we were surprised to find Barbie dolls implicated in Covid funding scams. Pictures of doll faces and other figurines were paired with fake identities used to apply for cash from the government. What other Covid cash corruption do you know about? Let me know — and be sure to share other health news — at dpayne@politico.com. TODAY ON OUR PULSE CHECK PODCAST, host Kelly Hooper talks with Katherine Ellen Foley, who gives an overview of the shifting Alzheimer’s drug landscape as drugmakers focus on developing the next class of treatments.
