Four Massachusetts towns have asked residents to stay indoors after 6 PM to avoid a dangerous mosquito-borne illness.
Eastern equine encephalitis (EEE) is back in the area for the first time since 2020, with one person hospitalized.
EEE is rare but serious - it can cause brain swelling and is fatal in about 30% of cases.
The "lockdown" is voluntary, but towns are rescheduling outdoor activities to safer hours.
Health experts say using mosquito repellent and reducing standing water are good ways to protect yourself.
While EEE is concerning, one doctor noted it's still "extraordinarily rare" - even rarer than being struck by lightning!
