California health departments are fighting to contain measles outbreaks as cases rise and resources shrink. Investigating communicable diseases is time-intensive and expensive. Officials say teams have about 72 hours after a positive case to find exposed people and stop spread. Nurses trace contacts, order quarantine, or give post-exposure medicine. They then monitor people for 21 days. Experts say measles spreads fast and hangs in the air for hours. California has high vaccination rates overall, but unvaccinated pockets drive outbreaks. The outbreaks are occurring as local health departments also face major funding cuts and staffing losses.
New options for testing and treating some of the most common sexually transmitted diseases are becoming available. In the past year, U.S. health officials approved new home-based tests that can detect common infections like gonorrhea, chlamydia and HPV. The Food and Drug Administration also approved two new drugs for gonorrhea, the first new options in decades. Experts hope the trend toward access and convenience will keep downward pressure on infection rates. Cases of sexually transmitted diseases have been falling for several years after spiking during the COVID-19 pandemic.
A mosquito-borne virus more common in South America has been detected in the United States. Health officials say the chikungunya virus has been identified in a patient living in the suburbs of New York City who began experiencing symptoms in August. Authorities say it's the first locally acquired case identified in any state since 2015, meaning the patient didn't travel outside the country before becoming infected. It's also the first locally acquired case that New York has ever seen. Chikungunya typically produces symptoms including fever, muscle pain, nausea, fatigue and a rash.
A recent study of schoolchildren finds that the youngest students harbor the most germs. Researchers looked at nasal swabs and symptom reports of more than 800 students and staff in Kansas City, Missouri. Kids in pre-kindergarten and elementary school had the highest rates of virus detection compared with older students and staff. The pre-K kids, ages 3 to 5, had the highest rates of actual illness, too. Young children can have up to 10 respiratory viruses as their immune systems are introduced to different infections for the first time. Those viruses include colds, flu and more.
A Maryland resident who traveled to El Salvador has been diagnosed with New World screwworm. It's the first reported U.S. case tied to travel to a country with a current outbreak. The Centers for Disease Control and Prevention confirmed the diagnosis three weeks ago. Federal health officials acknowledged the infection in an emailed statement Monday. Health officials say the parasite does not spread from person to person and that the risk to the public is very low.
