Bold warning: healthcare workers are at real risk, and the clock is ticking. The Nigeria Centre for Disease Control and Prevention (NCDC) has issued a public health advisory urging heightened vigilance and strict infection control as Lassa fever cases rise among medical staff. Here’s what you need to know, explained clearly for beginners, with practical context and a few provocative angles to consider.
The key message from the NCDC is simple: protect health workers first. In the advisory issued at the height of the 2025/2026 Lassa fever season, NCDC confirmed 15 healthcare workers testing positive for Lassa fever and two deaths as of Epidemiological Week 7. The agency emphasizes that safeguarding clinicians, nurses, and other frontline personnel must be the top priority, and it calls on all health workers to adopt every precaution necessary to prevent infection and loss of life.
Where the risk is highest and why it matters
- Infections among health workers have been reported across several states, especially in areas with high disease burden like Ondo, Edo, Bauchi, Taraba, Ebonyi, and Benue. Some outbreaks are linked to specific local government areas.
- Investigations into each case have revealed troubling gaps in infection prevention and control (IPC) practices. In other words, risk isn’t random—it’s tied to how well IPC measures are followed in practice.
- The gaps identified include a low index of suspicion among staff, inconsistent PPE availability and improper use, and underestimation of risks in outpatient departments and general wards. These gaps can lead to misaligned prevention strategies and, tragically, fatalities.
Important warning signs and misperceptions
- Undiagnosed patients frequently present in outpatient units and general wards, not just in isolation units. This challenges the assumption that only high-security areas pose a threat.
- Non-clinical staff—cleaners, porters, administrative personnel—are also at risk and must be included in IPC training and protection plans.
- There is often a six-day average delay between symptom onset and seeking care. Causes include fear of stigma and self-medication at home. The advisory stresses that healthcare workers should not self-treat and must report symptoms or exposure promptly.
What increases the chance of transmission in healthcare settings
- Direct contact with infected body fluids such as blood, urine, or vomit
- Performing procedures without adequate PPE
- Poor hand hygiene and handling of contaminated instruments
- Delayed recognition and isolation of suspected cases
- A general failure to apply standard precautions to all patients at all times
What to do now: practical steps for facilities and workers
- Ensure constant availability and proper use of PPE: gloves, masks, respirators, eye protection, gowns, and disinfectants.
- Maintain rigorous hand hygiene: wash before and after every patient contact, after body-fluid contact, and after glove removal; use alcohol-based rub when hands aren’t visibly soiled.
- Create and sustain functional isolation areas and designated treatment centers where possible, with clear referral pathways for suspected cases.
- Report any suspected Lassa fever cases immediately to the local disease surveillance officer or via the NCDC toll-free line, 6232.
- Deploy Rapid Response Teams to hotspots, distribute IPC supplies, and conduct targeted training in treatment centers.
Clear recognition of the broader lesson
Protecting healthcare workers is central to controlling Lassa fever. Early detection, strict IPC adherence, and coordinated state-level action can save lives and prevent further spread. While some states have begun to take decisive action, the continued emphasis on IPC and rapid reporting is essential across all facilities.
Controversial angle to consider
Some observers argue that despite IPC guidelines, systemic constraints—such as funding, staffing levels, and supply chains—limit real-world protection. Others contend that even with imperfect resources, consistent, disciplined practices can dramatically reduce transmission. Which view do you find more persuasive, and why? Do you think the balance between ideal IPC standards and practical constraints should shift in favor of stricter adherence or smarter prioritization? Share your perspective in the comments.
