Measles cases are on the rise, with the first confirmed case in Jersey in eight years and 14 reported cases in Marion County, Oregon, since mid-June. Public health authorities are urging vaccination, particularly the MMR vaccine, as measles is highly contagious and can lead to severe health issues for vulnerable populations, including infants and pregnant individuals. In Oregon, the majority of cases have occurred in unvaccinated individuals, with a significant uptick in nationwide cases reported by the CDC. Meanwhile, an adult international traveler in Orange County has also been confirmed to have measles, prompting health officials to contact potentially exposed individuals. Health experts emphasize the importance of maintaining updated vaccination schedules, especially before international travel. Symptoms of measles include fever, cough, runny nose, and a distinctive rash, with contagiousness extending before and after symptom onset.
