5 Critical Public Health Alerts From The Southern Nevada Health District (SNHD) For 2025-2026
The Southern Nevada Health District (SNHD) continues to serve as the critical public health backbone for more than 2.3 million residents across Clark County, Nevada, including the greater Las Vegas metropolitan area. As of late 2025, the SNHD is actively managing a complex array of public health challenges, from the ongoing rollout of the 2025–2026 COVID-19 and flu vaccination campaigns to tackling a concerning rise in congenital syphilis and HIV cases.
The agency’s strategic focus for the 2025-2026 season is centered on infectious disease surveillance, health equity, and environmental regulation, all while operating under new executive leadership. Residents and visitors to Las Vegas, North Las Vegas, and Henderson should be aware of the most recent advisories and the essential community services available through the SNHD's Main Facility on Decatur Boulevard and its various Public Health Centers.

SNHD’s Top 5 Public Health Priorities for the 2025-2026 Season
The Southern Nevada Health District has issued several key advisories and launched new tools to combat infectious diseases, reflecting the most pressing concerns for Clark County in the current health season. These efforts are part of the district's commitment to preventive care and robust disease surveillance.
1. Aggressive Response to Syphilis and Congenital Syphilis
One of the most critical and alarming health advisories issued in August 2025 concerns the sharp rise in syphilis cases, particularly congenital syphilis, which affects newborns.
The SNHD has implemented a Mandatory Rapid Syphilis Screening requirement for all pregnant persons in Clark County.
This proactive measure is designed to identify and treat cases early, directly addressing the concerning trend highlighted in the 2025 Southern Nevada Community Health Assessment Report.
2. The New Respiratory Disease Dashboard
In a significant step toward enhanced public health transparency and data accessibility, the SNHD launched a new Respiratory Disease Dashboard.
This user-friendly online tool consolidates up-to-date data on multiple concurrent threats:
- Influenza (Flu) Activity
- COVID-19 Case Counts and Trends
- Respiratory Syncytial Virus (RSV) Activity
The dashboard allows residents and healthcare providers to monitor the combined impact of these viruses, enabling better decision-making regarding vaccination and preventative measures.
3. Updated 2025-2026 COVID-19 and Flu Vaccination Campaigns
Following updated guidance, the SNHD is actively distributing the latest COVID-19 vaccine formulation for the 2025–2026 season.
Vaccines are available at SNHD Immunization Clinics, including the Main Facility and the East Las Vegas Public Health Center, for all individuals six months and older.
A major focus of this campaign is ensuring access for vulnerable populations, including uninsured and underinsured individuals, as well as those who qualify through the federal Vaccines for Children (VFC) program.
4. Surveillance of Measles and Other Communicable Diseases
The SNHD issued a public health advisory in August 2025 after Measles was detected in wastewater samples collected in Clark County.
This detection underscores the need for high community vaccination rates and robust public health surveillance, particularly in a high-traffic tourist hub like Las Vegas.
Furthermore, the district continues to battle a rising tide of HIV diagnoses, with 552 new cases reported in Clark County in 2024—an increase from 508 in 2023—making HIV/AIDS Prevention a constant, high-priority program.
5. Environmental Health and Regulatory Updates
The Environmental Health Division is responsible for everything from restaurant inspections to water quality (Aquatic Health Program).
In October 2025, the SNHD announced the postponement of a public hearing regarding proposed septic system regulations.
This delay allows the District to gather additional community and stakeholder input on the complex regulatory changes, ensuring a balanced approach to environmental safety and property owner concerns.
Beyond the Clinic: Essential Community and Preventive Health Initiatives
The Southern Nevada Health District’s work extends far beyond infectious disease control, encompassing a wide range of preventive care, health promotion, and community outreach programs.
Driving Health Equity and Access
The Health Equity Program is a cornerstone of the SNHD’s mission, actively working to eliminate health disparities across diverse populations in Southern Nevada.
A tangible example of this commitment is the May 2025 news regarding the support for a new greengrocer (produce store) in Las Vegas’ Historic Westside.
This initiative directly addresses food deserts and improves access to nutritious food, linking community development with public health outcomes.
Family and Child Health Services
The SNHD’s Southern Nevada Community Health Center (SNCHC), located at the Decatur Blvd. Main Facility, offers a comprehensive suite of family health services.
Key programs include:
- Childhood Lead Poisoning Prevention Program
- Embracing Healthy Baby and other child-related clinics
- The Nurse-Family Partnership, which provides support for first-time mothers.
These services are vital for ensuring the health and well-being of the youngest and most vulnerable members of the Clark County community.
Chronic Disease Prevention and Wellness
The Chronic Disease Prevention & Health Promotion program focuses on long-term wellness, tackling conditions like diabetes, heart disease, and obesity.
By offering community-based education and resources, the SNHD aims to reduce the prevalence of preventable illnesses that place a significant burden on the regional healthcare system.
The integration of data from the new Respiratory Disease Dashboard into these programs allows for a holistic view of community health, recognizing that acute and chronic conditions often intersect.
Conclusion: The SNHD’s Role in a Dynamic Metropolis
The Southern Nevada Health District (SNHD) is an essential, constantly evolving entity, crucial to the health and safety of Las Vegas and the entire Clark County region.
Under the new leadership of Dr. Cassius Lockett, the district is aggressively tackling 2025-2026 health challenges, from implementing mandatory syphilis screenings for pregnant persons to managing the rollout of updated respiratory vaccines.
By combining high-level disease surveillance, community-focused initiatives like the greengrocer project, and accessible clinical services at locations like the 280 S. Decatur Blvd. Main Facility, the SNHD remains the primary guardian of public health in one of America’s most dynamic metropolitan areas.
