The Centers for Disease Control and Prevention (CDC) has reported that the United States is experiencing its highest number of measles cases in over three decades, with 1,288 confirmed cases across 38 states as of mid-2025. This marks a significant increase from the 285 cases recorded in the previous year, highlighting a troubling trend in public health.

The last time the US saw such high numbers was in 1992, prior to the disease being declared eliminated in 2000 due to effective vaccination programs. Experts are alarmed by the resurgence, noting that measles is one of the most contagious diseases known to humans. Dr Caitlin Rivers from Johns Hopkins University emphasized the preventability of measles, stating, "We really hate to see this resurgence of a preventable virus.".

Major Outbreaks and Hospitalizations

The largest outbreak has been reported in Texas, which has accounted for 753 of the total cases. The outbreak began in January and, at its peak, was seeing 15 to 20 new cases daily. Although the rate of new cases has slowed, the overall trend indicates that the US is experiencing more cases weekly than in previous years.

As of now, over 150 individuals have been hospitalized due to measles, and three deaths have been reported, including two unvaccinated children in Texas. The CDC has noted that 92% of the confirmed cases are among individuals who are unvaccinated or whose vaccination status is unknown.

Declining Vaccination Rates

The resurgence of measles is closely linked to declining vaccination rates across the country. Kindergarten vaccination rates have dropped from 95% during the 2019-2020 school year to less than 93% in 2023-2024. Dr Adam Ratner, a pediatric infectious disease physician, warned that the US is in danger of losing its measles elimination status if vaccination rates do not improve.

The CDC recommends that children receive two doses of the measles, mumps, and rubella (MMR) vaccine, with the first dose administered between 12 to 15 months of age and the second between 4 to 6 years. One dose of the vaccine is 93% effective, while two doses increase effectiveness to 97%.

Public Health Implications

The current situation serves as a warning sign for public health officials. Dr Peter Hotez, a professor of pediatrics, expressed concern that the US could see a return of other childhood illnesses if vaccination rates continue to decline. He noted that measles outbreaks often precede the resurgence of other vaccine-preventable diseases, such as whooping cough.

The CDC continues to support community vaccination efforts and provides technical assistance and vaccines to areas experiencing outbreaks. However, the decision to vaccinate remains a personal choice, which complicates efforts to achieve herd immunity.

Conclusion

The rise in measles cases in the US is a significant public health concern, reflecting broader issues related to vaccination hesitancy and declining immunization rates. As health officials work to combat this trend, the importance of vaccination as a preventive measure against measles and other infectious diseases cannot be overstated. The situation underscores the need for renewed public health campaigns to educate communities about the benefits of vaccination and the risks associated with preventable diseases.

Flu Activity in the U.S. Expected to Rise for Weeks, CDC Warns

Flu activity in the United States is projected to continue increasing over the coming weeks, according to Dr Carrie Reed from the CDC. Current estimates indicate over 11 million illnesses and a new variant, subclade K, is now the dominant strain. Health officials emphasize the importance of vaccination and early treatment with antivirals for those at higher risk.

Minnesota Experts Alarmed by New CDC Vaccine Recommendations

Health experts in Minnesota are expressing serious concerns over new CDC childhood vaccine recommendations following significant changes in the Advisory Committee on Immunization Practices (ACIP). The recent overhaul, led by Robert F. Kennedy Jr, has raised alarms about potential erosion of public trust in vaccines and the implications for child health.

Flu-like Illness Activity Reaches Record Highs in the U.S.

New data from the CDC reveals that flu-like illness activity in the US has reached its highest recorded levels, with significant increases in hospitalizations and cases. The surge is primarily driven by a new strain of the flu virus, prompting health officials to emphasize the importance of vaccination.

FDA Rejects Outlook's Eye Drug Lytenava for Second Time

The FDA has declined to approve Outlook Therapeutics' eye disease drug, Lytenava, for the second time, citing insufficient evidence of effectiveness. This decision follows a previous rejection in 2023 due to manufacturing issues and the need for more clinical data.

Flu Cases Surge as CDC Reports Rising Hospitalizations

Flu cases in the US are surging, with over 19,000 hospital admissions reported last week alone. The CDC attributes this rise to a new strain of the virus, and experts warn that the situation may worsen as the season progresses.
