As we move into the latter part of March 2025, the realm of global health is facing alarming challenges that demand our attention. Here's an overview of the most pressing outbreak news and health disruptions affecting us today.

Measles Outbreak Intensifies

According to the latest report from the Centers for Disease Control and Prevention (CDC) on March 14, 2025, the United States is grappling with a significant measles outbreak, with a staggering 301 confirmed cases and 2 reported deaths—one confirmed and another still under investigation. Notably, 17% of those affected have required hospitalization. This year's figures reveal a stark contrast to 2024, which saw only 285 cases total.

Breaking down the demographics, it’s clear that unvaccinated populations are at the greatest risk. Among those 301 cases, 42% occurred in individuals aged 5-19, 34% in children under 5, and 21% among adults over 20. Alarmingly, 95% of all cases are linked to individuals who are either unvaccinated or have uncertain vaccination status. The CDC specifies that over 280 of these cases are associated with outbreaks, emphasizing the urgent need for vaccination awareness campaigns.

Concerns Over H5N1 and H7N9 Avian Influenza

In addition to the measles situation, the agricultural sector is under pressure due to the ongoing H5N1 avian flu outbreak. As of March 18, 2025, the U.S. has reported 70 human cases, including a tragic death. Most of these infections stemmed from exposure to dairy herds, with the remaining cases linked to poultry farms and culling operations. The virus has been detected in a staggering 12,581 wild birds and 989 dairy herds across 17 states, sparking urgent biosecurity responses from the USDA.

Compounding these concerns is the emergence of the H7N9 strain of highly pathogenic avian influenza (HPAI) on a poultry farm in Mississippi, raising alarms due to its higher mortality risk in humans.

Global Health Disruptions: A Call for Action

The ramifications of U.S. withdrawal from the World Health Organization (WHO) and cuts to USAID funding have become increasingly dire. The disruption has had a cascading effect on critical health services worldwide—ranging from HIV/AIDS treatments to malaria diagnostics and tuberculosis prevention programs. Despite the WHO's recent positive updates, including no new Ebola cases in Uganda and a successful rollout of malaria vaccines in Burundi, the underlying issues persist.

Dr. Tedros Ghebreyesus, WHO's Director-General, recently highlighted the grave impact of U.S. funding cuts, urging reconsideration from U.S. officials. "Without corrective measures, we face the harrowing prospect of an additional 15 million malaria cases and over 107,000 malaria-related deaths this year, effectively negating years of progress," he warned.

The suspension of the PEPFAR initiative, vital for combating HIV/AIDS, has critically disrupted treatment and prevention services in over 50 nations. The looming crisis threatens to escalate HIV cases and deaths significantly, reversing two decades of progress in combating the epidemic.

As surveillance capabilities diminish due to resource shortages, the global community faces a compounding risk. Early warning systems for infectious diseases, once robust, are now jeopardized—endangering lives worldwide.

With health officials around the globe on high alert, there is a collective call to action. Public health responses must be intensified to mitigate the spread of these infectious diseases and safeguard the hard-won progress in global health. The time to act is now!
