Manchester, NH - The tuberculosis (TB) outbreak initially linked to a Manchester construction site is proving more complex than initially anticipated, with health officials now expanding investigations to include other large-scale construction projects across the state and reviewing potential systemic failures in worker health and safety protocols. As of today, Wednesday, April 1st, 2026, the New Hampshire Division of Public Health has confirmed 37 cases, a significant increase from the initial handful reported last month. While the outbreak remains largely concentrated in the Manchester area, cases have now been identified in Nashua and Concord, prompting a statewide alert.

Dr. Emily Carter, Director of the New Hampshire Division of Public Health, addressed the public today, stating, "The situation has evolved. While the original construction site remains a central focus, the geographical spread and the profiles of some new cases suggest the possibility of wider transmission networks. We are now operating under the assumption that this isn't an isolated incident, but rather a symptom of broader vulnerabilities in how we protect the health of our construction workforce."

The initial investigation centered on the Manchester site, a large mixed-use development employing a diverse workforce. Preliminary findings continue to point to airborne transmission fueled by the site's often-confined spaces and inadequate ventilation. However, subsequent interviews with former employees have revealed a pattern of limited access to respiratory protection, insufficient training on infectious disease prevention, and a culture of prioritizing speed over safety. Several workers reported feeling pressured to continue working despite experiencing early symptoms of respiratory illness, contributing to potential onward transmission.

"We are seeing a disproportionate number of cases among newly arrived immigrant workers," explained Dr. David Lee, the lead epidemiologist on the outbreak response. "Language barriers and a lack of familiarity with the American healthcare system may have delayed diagnosis and treatment in some instances. We're working with community organizations to ensure these individuals receive culturally sensitive care and support."

The state is now conducting comprehensive inspections of all active large-scale construction projects, focusing on ventilation systems, air quality, and adherence to Occupational Safety and Health Administration (OSHA) regulations regarding respiratory protection. Several violations have already been identified, leading to temporary work stoppages and substantial fines for non-compliant companies.

Beyond the immediate health crisis, the outbreak has ignited a debate about the adequacy of New Hampshire's public health infrastructure. The last significant TB outbreak in the late 1990s exposed weaknesses in the state's contact tracing and testing capabilities, issues that appear to be resurfacing. Advocates are calling for increased funding for public health programs, including expanded screening capacity, enhanced disease surveillance, and improved worker health protections.

The economic impact of the outbreak is also becoming increasingly apparent. The temporary shutdown of construction projects has disrupted supply chains and delayed completion dates. Local businesses near the affected sites are reporting decreased foot traffic. The state government is exploring potential financial assistance programs to mitigate the economic hardship.

The New Hampshire Department of Labor is collaborating with the Division of Public Health to develop mandatory training programs for all construction workers on infectious disease prevention, including proper mask usage, hand hygiene, and symptom recognition. These programs will be offered in multiple languages to ensure accessibility for all workers. Furthermore, officials are exploring the implementation of regular, proactive TB screening for construction workers, particularly those working in high-risk environments.

The Centers for Disease Control and Prevention (CDC) has offered its support, sending a team of experts to assist with the investigation and provide technical guidance. They are analyzing genetic sequencing data from the identified TB strains to determine the source of the outbreak and track its spread. This data will be crucial in understanding the effectiveness of current control measures and informing future prevention strategies.

The state continues to urge anyone experiencing symptoms of TB - such as a persistent cough, fever, night sweats, or weight loss - to seek medical attention immediately. Information and resources are available on the New Hampshire Division of Public Health website and through a dedicated hotline.
