The United States has recently experienced outbreaks of several infectious diseases, including measles, mpox, and HIV, which have exposed critical gaps in the nation’s public health systems, according to Dr. Monica Gandhi, a professor of medicine at the University of California, San Francisco (UCSF). These outbreaks underscore the need for improved surveillance, rapid response capabilities, and accessible diagnostic tools to contain and manage infectious diseases effectively.
Dr. Gandhi, an expert in infectious diseases, highlighted that the outbreaks reveal underlying weaknesses in public health infrastructure, such as insufficient funding, fragmented systems, and disparities in access to healthcare. The resurgence of measles, a vaccine-preventable disease, points to declining vaccination rates and gaps in immunization coverage. Similarly, the spread of mpox (formerly known as monkeypox) and ongoing HIV transmission indicate challenges in reaching at-risk populations with prevention and treatment services.
In response to these challenges, several companies are working to develop advanced diagnostic tools that can be used at point-of-care facilities and even at home. One such company is Co-Diagnostics Inc. (NASDAQ: CODX), which is striving to create rapid, accurate tests that can be deployed in diverse settings. As these tools become widely available, they could significantly enhance the ability to detect and respond to outbreaks quickly, potentially reducing transmission and improving health outcomes.
The importance of accessible diagnostics was underscored during the COVID-19 pandemic, when rapid testing played a crucial role in controlling spread. Similar approaches are now being applied to other infectious diseases. Point-of-care tests for HIV, for example, can provide results in minutes, enabling immediate linkage to care. For measles and mpox, early detection can help public health officials implement containment measures more effectively.
However, experts caution that diagnostic tools alone are not sufficient. Strengthening public health systems requires sustained investment in surveillance, workforce training, and community engagement. Dr. Gandhi emphasized that addressing social determinants of health, such as poverty and housing instability, is also critical to reducing disease burden.
The recent outbreaks serve as a wake-up call for policymakers to prioritize public health funding and infrastructure. Without systemic improvements, the U.S. may continue to face recurrent outbreaks that strain healthcare resources and disproportionately affect vulnerable communities.
