United States – Measles cases in the United States at least tripled this year, based from the reported outbreaks and cases up to July 25, which was much higher than outbreaks in the past year. Currently, the CDC reports that 188 measles diseases happened in the 25 states and the District of Columbia during the period, 58 in 2023, as reported by HealthDay.
Transmitted to Children and Other Sensitive Groups
From them, 43% were children below 5 years, while 32% were those above 20 years. The CDC pointed out that the 95 percent of the affected people did not receive the vaccine, or their vaccination history was not known, or they received only one dose of the MMR vaccine. Available research reveals that the MMR vaccine is 93% effective after the first dose and 97% effective when the second dose is included.
Increase in Outbreaks
In this regard, the health authorities have reported 13 measles outbreaks inclusive of three or more cases in contrast to 4 outbreaks in the previous year only. Around 64% of the total infection cases this year have been associated with these outbreaks. The highest death rate was reported in March in a migrant shelter in Chicago where 57 people got infected. The Chicago Department of Public Health gave the signal that the outbreak was over on 30 May following 42 days without a single fresh case.
High Transmission Rates and Serious Health Risks
Measles is highly contagious, with up to 90% of unvaccinated individuals contracting the disease upon exposure to an infected person. Symptoms typically appear within seven to 14 days and include fever, skin rash, and severe complications such as pneumonia, brain swelling, and potentially death.
Historical Context and Current Challenges
Measles was declared eliminated in the U. S. in 2000 due to vigorous vaccination campaigns and mandatory state laws of MMR vaccination for children enrolments in kindergartens of public schools. However it has used a revival in the recent past due to lesser immunization in schools and increased measles cases globally. In the U. S. , there were 382 cases in 2018 and 1,274 in 2019 that was the most lethal year since 1992.
Travel-Related Risks
The domestic airports are recognized as places in which one is most likely to meet a foreign measles traveler. Therefore, the Los Angeles County Department of Public Health has reported a measles case with a passenger who arrived at the Los Angeles International Airport on July 26 while overseas, as reported by HealthDay.
Public health officials made a point that everybody must get fully vaccinated to avoid the diseases such as measles from spreading. The CDC currently remains vigilant and key outbreak places and measures to prevent are shared on the CDC website.
