Top Public Health Threats to Watch in 2025: Key Challenges and Global Risks

Magazine, Living Well

As the world continues to grapple with evolving health challenges, experts are sounding the alarm on several critical public health threats that demand immediate attention in 2025. From the far-reaching impacts of climate change on disease spread to the resurgence of influenza and the ongoing battle against COVID-19, the global healthcare landscape is at a crossroads. In a recent Ethnic Media Services briefing, a distinguished panel of public health authorities—Dr. Nahid Bhadelia, founding director of the Center for Emerging Infectious Diseases at Boston University; Dr. Peter Chin-Hong, infectious disease specialist at the University of California, San Francisco; Dr. Benjamin Neuman, biology professor at Texas A&M University; Dr. Maurice Pitesky, veterinary epidemiologist at UC Davis; and Dr. William Schaffner, professor of medicine at Vanderbilt University—shared their insights on the pressing issues affecting both local and global health security. This in-depth discussion highlighted the interconnectedness of emerging diseases, the importance of vaccines, and the urgent need for international collaboration to mitigate future outbreaks. With new viruses like MPOX and avian flu on the rise, these experts offered a comprehensive look at the risks, responses, and strategies that will shape the public health agenda in the year ahead.

The discussion began with a central question: What is the most significant public health challenge today? Dr. Bhadelia provided a broad perspective. “It’s difficult to pinpoint just one issue, but climate change is a pervasive threat that impacts nearly everything,” she explained. “It affects the spread of infectious diseases, disrupts healthcare systems, and makes outbreaks more difficult to predict. Moreover, climate-related disasters strain medical supplies and heighten vulnerabilities.”

Dr. Chin-Hong followed by raising concerns about the resurgence of influenza, particularly avian flu. “Influenza, especially avian flu, is a growing worry,” he noted. “We’re seeing its impact on humans, animals, and domesticated species. What’s even more troubling is the rising resistance to science—anti-vaccine sentiment undermines our ability to use existing tools to tackle these threats effectively.”

Dr. Neuman highlighted the troubling trend of declining vaccination rates. “We are witnessing a concerning erosion of herd immunity,” he warned. “Fewer people are getting vaccinated for preventable diseases, extending well beyond COVID-19. This puts decades of progress at risk, creating gaps in our defenses and making future outbreaks more difficult to control.”

Dr. Schaffner then addressed the strain on healthcare systems, pointing out the current surge in respiratory illnesses. “Our hospitals are overwhelmed with cases of influenza, COVID-19, and RSV,” he said. “Factors such as holiday gatherings, increased travel, and children returning to school have accelerated the spread of these viruses. The need for effective prevention measures is critical.”

The panel then turned to the U.S.’s role in global health security. Dr. Bhadelia emphasized the importance of international collaboration, drawing on her extensive policy experience. “The U.S. has long been a leader in global health initiatives,” she said. “Through programs like PEPFAR and partnerships with the WHO, we’ve built trust, strengthened global health systems, and saved millions of lives. If we pull back from these commitments, we not only lose our leadership but also risk being unprepared for the next pandemic.”

She further stressed the interconnectedness of health security: “What circulates in Congo today could be in Colorado tomorrow. Diseases know no borders. If we isolate ourselves, we jeopardize our ability to detect and respond to threats early.”

Dr. Chin-Hong then discussed two emerging viruses gaining a foothold in the U.S.—MPOX and Oripush. “The first case of MPOX in the U.S. was detected in the Bay Area last November,” he said. While he did not expect a major outbreak this year, he cautioned that the strain circulating since 2022 remains a serious concern. “What worries me is that people seem to have forgotten its risks and are not keeping up with vaccinations.”

Dr. Chin-Hong provided further insight into the MPOX virus, explaining the different clades. “The original clade, clade 1, was transmitted through animal contact. But clade 1B, which emerged in 2022, is more concerning. It spreads through both animal and human contact, including sexual contact, and has led to over 150,000 cases and more than 1,000 deaths, mainly among children under 15.”

He also highlighted the disproportionate impact on children, particularly in regions like Africa, where co-infections with diseases like malaria and malnutrition complicate the severity of MPOX.

On vaccines, Dr. Chin-Hong stressed the importance of completing the JYNNEOS vaccination series, which is recommended for at-risk individuals, including gay and bisexual men and those in occupational settings exposed to MPOX. Unfortunately, only about 25% of eligible individuals have completed the two-dose regimen, leaving significant gaps in immunity.

Dr. Chin-Hong also pointed to the global response to MPOX, noting the deployment of the LC16 vaccine in Africa. “Equitable distribution of vaccines and education campaigns are essential for tackling MPOX globally,” he concluded.

The panel then turned to updates on COVID-19 and related challenges. Dr. Newman discussed the highly transmissible XEC subvariant of COVID, which emerged in October. “We are seeing multiple viruses—RSV, norovirus, flu, and COVID—circulating simultaneously,” he said. “This phenomenon is driven more by human behavior and seasonal gatherings than the viruses themselves.”

Dr. Newman also expressed concern about the ongoing decline in vaccination rates, particularly for non-mandated vaccines like the flu shot. He highlighted the risk of a resurgence of diseases like measles and whooping cough, which were once well-controlled through vaccination efforts. “School-mandated vaccines were crucial in eradicating diseases like polio, and we must not allow immunization rates to fall,” he warned.

Despite challenges, Dr. Newman remained cautiously optimistic about the current vaccines’ ability to protect against rising strains. “The vaccines appear to be effective against variants like JN1 and KP3,” he said, urging the public to get vaccinated to prevent further spread.

In a call to action, Dr. Newman likened the current situation to A Christmas Carol, suggesting that while rising infections are concerning, “the clock hasn’t struck midnight yet.” He urged the public to act now to mitigate the impact of the ongoing virus season.

Dr. Maurice Pitesky, a veterinary epidemiologist, then provided a critical update on the H5N1 avian flu outbreak. “This virus is spreading across six continents, affecting wild and domestic birds, mammals, and even wastewater,” he warned. “Its adaptability is a serious concern, particularly if it begins to transmit between humans.”

Dr. Pitesky emphasized the importance of influenza vaccines for at-risk populations and the need for stronger surveillance and preventive measures. He also noted the challenges in reaching undocumented and migrant workers, advocating for increased collaboration between public health agencies, the CDC, and agricultural industries.

The discussion concluded with a call for coordinated efforts to address emerging infectious threats. Dr. Pitesky’s insights underscored the interconnectedness of public health, agriculture, and global biosecurity. As the panel’s experts concluded, vigilance, international cooperation, and equitable access to vaccines will be key to safeguarding public health and preventing future pandemics.
