Early information suggests the patient may have had contact with rodents while in West Africa, the CDC said.

Infections with the bacteria that causes walking pneumonia have risen significantly this year, particularly among young children, the Centers for Disease Control and Prevention warned this month. The bacteria, called Mycoplasma pneumoniae, spreads through coughs and sneezes and can cause respiratory illnesses. Cases have risen among adults and children, but the most notable increase has been among children between 2 and 4, which experts say is striking given that the bacteria typically infects older children. Data suggests that doctors have diagnosed a growing number of children in this age group with infections after they sought treatment in emergency rooms for pneumonia. (Blum, 10/29)

Get ready for a big debate over the amount of red meat on your plate. Scientists advising the U.S. government on its next round of dietary guidelines have drafted recommendations that would tell Americans to limit how much red meat they eat. It is part of an effort to nudge us to eat more plant foods, including beans, peas and lentils. The draft recommendations have drawn an immediate outcry from the meat industry, setting up a potential fight over the final guidelines—expected late next year—and the amount of red meat we should have in our diets.

Climate change is increasingly disrupting people’s sleep. High nighttime temperatures led to 5% more hours of sleep lost worldwide over the past five years compared to the period between 1986 and 2005, according to the latest edition of the Lancet’s study of climate and health. It marks the first time the prestigious medical journal has examined this metric. Sleep loss peaked in 2023, the hottest year on record, when there was a 6% rise. (Rudgard, 10/30)
