The Lagos State Government has officially sounded a public health red alert following a surge in Lassa fever cases across Nigeria. In response to the escalating crisis, the state has launched an aggressive statewide awareness and prevention campaign to insulate the megacity from a full-scale outbreak.
The Commissioner for Health, Prof. Akin Abayomi, revealed that the country is currently battling one of its most severe outbreaks in recent history. National data recorded between January and mid-March 2026 shows a staggering 660 confirmed cases and 167 deaths spanning 22 states.
Frontline Risks and National Impact
A deeply concerning aspect of the current wave is the high rate of infection among medical personnel. Prof. Abayomi disclosed that 38 healthcare workers have contracted the virus since the start of the year, resulting in the deaths of three doctors.
“When a disease begins to kill frontline workers, that is a serious warning sign,” Abayomi stated. “The situation underscores the need for heightened vigilance, strict infection prevention protocols, and rapid response systems to protect those who protect us.”
The Commissioner noted that while Lagos is not an endemic zone, its status as a global commercial hub makes it highly vulnerable to imported cases. He warned that the daily influx of thousands of people via road and air creates a high-risk environment for rapid transmission, drawing parallels to the early days of the COVID-19 pandemic.
The Silent Threat of Asymptomatic Spread
Lassa fever, a zoonotic viral illness spread primarily by rodents, has evolved in its transmission patterns. According to health officials, the disease is moving away from seasonal peaks toward year-round transmission. This shift is largely attributed to environmental changes and increased human contact with wildlife.
A major challenge for containment is that roughly 70 percent of infected individuals show mild or no symptoms. These silent carriers remain infectious, posing a significant risk in the densely populated urban centers of Lagos. For the remaining 20 percent who develop symptoms, the disease can be catastrophic, often leading to internal bleeding and organ failure if treatment is delayed.
State Response and Ecological Drivers
Prof. Abayomi categorized Lassa fever alongside Ebola and Marburg as pathogens of high consequence. He linked the rising frequency of these viral outbreaks to climate change, deforestation, and ecological disruptions that push wildlife closer to human settlements.
To combat these threats, Lagos has activated its 24-hour Emergency Operations Centre and reinforced its digital surveillance systems. The state is also conducting continuous biosecurity training for healthcare staff to ensure they are equipped for early detection and isolation.
“Preparedness is not panic response; it is leadership,” Abayomi emphasized. He assured residents that the state is collaborating with the Nigeria Centre for Disease Control (NCDC) and the Federal Ministry of Health to maintain a robust defense. The newly launched campaign aims to empower communities with the knowledge to reduce rodent contact and report early symptoms, ensuring the virus is contained before it can escalate into a local emergency.
