The resident had recently returned from West Africa. Iowa health officials say the risk of transmission is "incredibly low." Also in the news, locally acquired malaria, "walking pneumonia" in children, bird flu in California, and more.

For the first time in 20 years, the United States recorded locally acquired malaria cases last year. A report published late last week in Morbidity and Mortality Weekly Report details the 10th US case, in Arkansas. The previous cases were in Florida, Texas, and Maryland. Since the 1970s, cases of travel-associated malaria have ticked upward in the United States, with 2,048 such cases recorded in 2019 by the Centers for Disease Control and Prevention (CDC). (Soucheray, 10/28)
In the days before Kamberlyn Bowler became ill, she went to McDonald’s several times for her favorite meal: a Quarter Pounder with cheese and extra pickles. The previously healthy, active 15-year-old is now hospitalized and battling kidney failure — a rare and potentially life-threatening complication of E. coli poisoning. Kamberlyn, of Grand Junction, Colorado, is one of dozens of people who say they became sick after having eaten McDonald’s Quarter Pounders. (Romans, Chuck and Allenbaugh, 10/29)
Respiratory infections among young children have been on the rise since the school year began in August, according to reports from the Centers for Disease Control and Prevention. Over the past six months, emergency rooms have discharged an increasing number of patients with a Mycoplasma pneumoniae diagnosis, which is typically associated with "walking pneumonia,"Â or acute bronchitis. Discharges peaked in late August, the CDC reported on Oct. 18. (Cross, 10/28)
On bird flu —
In experiments designed to learn more about the threat from the H5N1 avian flu virus spreading from cows to people, researchers found that an isolate from a sick dairy worker may be capable of replicating in human airway cells, is pathogenic in mice and ferrets, and can transmit among ferrets by respiratory droplets. The team, based at the University of Wisconsin at Madison and Japan, reported its findings today in Nature. Working in a high-containment lab, the researchers used an H5N1 isolate grown from the eye of a dairy worker who had experienced conjunctivitis after exposure to infected cows. (Schnirring, 10/28)
Merced County, California, has seen its first case of H5N1 bird flu, according to the Merced County Department of Public Health. The county said that the infected individual had direct contact with cattle at a Merced County dairy farm and laboratory tests confirmed the case after symptoms were detected following the direct exposure.

Dairy farmers in California are grappling with a steadily advancing outbreak of avian flu in their herds – a problem few of them want to talk about publicly, but that none of them can afford to ignore. Bird flu has been reported in more than 170 herds in California since late August, with the state accounting for nearly half of all US cases detected in dairy cows since the outbreak began in March.
