Diseases

Nigeria’s long struggle with disease outbreaks has repeatedly shown how weak communication systems can worsen health emergencies.

In recent years, states have battled diphtheria, malaria, meningitis, Lassa fever, cholera and measles, often without clear public guidance at the peak of outbreaks.

In many cases, rumors travelled faster than official updates. Fear spread before facts reached the public. Misinformation filled the gaps left by delayed or poorly coordinated communication.

With memories of these challenges still fresh, the Kano State Centre for Disease Control (KNCDC) has launched a major step meant to strengthen outbreak communication.

This comes through a three-day workshop in Zaria, supported by the Foreign, Commonwealth & Development Office (FCDO) Lafiya Programme.

The initiative seeks to unite health agencies, media professionals, risk communication experts and government institutions to create a stronger, faster and more reliable information system ahead of future outbreaks.

Officials say the programme will help states avoid the costly lessons of the past. During Nigeria’s diphtheria crisis, many communities were unaware of symptoms before outbreaks escalated.

During meningitis outbreaks, myths overshadowed medical guidance in some states. During the COVID-19 pandemic, conflicting messages damaged public trust.

These experiences, experts say, prove that communication failures can be as deadly as the diseases themselves.

The Director-General of KNCDC, Prof. Muhammad Adamu Abbas, declared the workshop open. He said the goal is no longer just to respond to outbreaks, but to communicate with clarity, speed and authority.

“This workshop is about building a united front — where health officials, journalists, and communication experts speak with one voice, guided by facts and science,” Prof. Abbas stated.

He described the partnership with FCDO-Lafiya as strategic, timely and necessary. He commended the organisation for sustained support in improving Nigeria’s health emergency systems.

He added that communication must stand alongside testing, vaccination and treatment in outbreak control.

Participants were drawn from health institutions, media organisations, government agencies and civil society groups.

They are expected to co-design a communication framework that prioritises rapid information flow, public engagement, rumor control and stakeholder alignment.

Facilitators will lead sessions on crisis media handling, digital risk communication, misinformation control, emergency coordination and broadcast-ready public messaging for disease outbreaks.

The workshop will also include group simulations, panel discussions and field scenarios aimed at turning knowledge into practice.

Public health analysts have strongly welcomed the initiative. They say outbreak preparedness in Nigeria must go beyond medical response. They argue that a well-informed public remains one of the strongest defenses during a health emergency.

Observers say Kano is taking a rare but necessary lead. Many states, they note, still lack structured outbreak information systems. Some states depend solely on federal communication during epidemics, leaving gaps in local response messaging.

Some wait until outbreaks are full-blown before launching public awareness efforts. Health experts warn that this delay has repeatedly cost lives.

By moving toward a structured communication plan, Kano is now positioning itself as one of the best prepared subnational systems in outbreak information management.

The workshop continues throughout the week, with officials stating that the final outcome will be a deployable outbreak communication model meant to guide real-time response within Kano and potentially across other Nigerian states.

Floods are natural disasters that occur globally, destroying lives and property, especially in developing countries like ours. As a natural disaster, it is caused by climate changes and human activities which distort the balance of environment, hosts and pathogens. Factors such as high sea level rise, urbanization, destruction of river banks, and deforestation increase the risk of flood disasters.

Flood results in the disturbance of the epidemiological triangle; environment, host and infectious agent, and as such, it could result in the emergence of new agents or re-emergence of infectious agents that previously existed. Therefore, the potential outbreak of infectious diseases is a matter of great concern, and urgent intervention is needed to break the chains of transmission.

Flood is known to increase the global burden of various infectious diseases, mortality, social and economic disruptions and displacement of people, which can result in both physical and psychological trauma. Of great concern is how flood causes the outbreaks of infectious diseases, as germs can easily be transported and contaminate drinking water sources, which will provide a conducive environment for the completion of the vector life cycle.

Like other developing countries, flooding has become an annual event in Nigeria, and many towns and cities are vulnerable and susceptible to it. This year, the Nigerian meteorological agency (NiMet) warned some states that they were at high risk of flooding in its yearly prediction of rainfall. Therefore, it was unsurprising that flooding hit many such states, states like Jigawa and Yobe have significantly been hit. In contrast, others such as Borno, Adamawa, Gombe, Kebbi, Kano, Kaduna, Lagos, Kogi, Niger, Delta, Rivers, Zamfara, Taraba, Ogun, Osun, Ondo, some parts of Ekiti, Edo and FCT are affected from moderately to low levels.

Flooding can cause waterborne diseases such as cholera, non-specific diarrhoea, typhoid and viral diarrhoea caused by Rotavirus. These diseases are known to peak after flooding as the pathogens such as bacteria, viruses, and parasites can be transported. In addition, the crowded nature of displacement camps can potentially result in and aggravate the outbreak of respiratory diseases.

The crowded nature of displacement camps can potentially result in the outbreak of respiratory diseases of different etiological agents. Wastewater is a breeding ground and carrier of infectious diseases. For instance, wastewater has the potential of spreading viruses, as they are known to be good-chance takers of a flood, which take days after flooding to meet their incubation cycle. Viral diarrheal diseases, such as hepatitis A and E, vector-borne viral diseases such as Yellow fever, and many others are also some diseases that could potentially spread after the flood.

The genome of some viruses, such as SARS-CoV-2, are known to be detected in community wastewater and this call for concern as it can be disseminated during a flood. Another agent to worry about due to flood is Naegleria fowleri, a brain-eating amoeba causing primary amoebic meningoencephalitis (PAM). As water level and temperature rise, such a situation could fuel the growth of the agent. Environmental contribution to the development of infectious diseases is a significant public health concern that should not be ignored. Antibiotic-resistant bacteria and antibiotic-resistant genes are quickly disseminated in environmental wastewater, which could be further transported into the water system, which calls for concern.

Furthermore, the vector-borne disease can occur as a result of a flood because the development cycles of vectors are provided. For instance, mosquito-borne diseases such as malaria and West-Nile fever tend to increase after floods. Rodent-borne diseases also expand during flooding because the flood increases contact between rodents and humans, resulting in outbreaks of such diseases. Common rodent-borne infectious agents due to flooding include Leptospirosis, Hantavirus pulmonary syndrome, Hemorrhagic fever with renal syndrome etc.

Health interventions

 First, public health measures are essential in preventing infectious diseases due to floods. Therefore, preventive measures should be taken before, during and after the flooding.

Second, the provision of crucial intervention. The critical intervention is an active early warning system that can alert governments to prepare for possible outbreaks and send signals for evacuation of people at risk.

Third, the activation of rapid emergency response is also a necessity. This includes the provision of basic materials and health care services.

Fourth, after the flood, the activation of an effective surveillance method is mandatory for the early detection of an outbreak.

The key intervention is active early warning systems which can alert governments to prepare for possible outbreaks and send signals for evacuation of people at risk. At this stage, all stakeholders and the public must act on time. However, compliance is low due to a lack of an alert system or people refusing to abide by the warning system. Furthermore, risk assessment is needed to ensure that no basic amenities are disrupted due to floods.

Moreover, there is a need for vector control after the flood to break the chains of transmission. There is a need for collaboration among all public health stakeholders. Public enlightenment and outreaches are equally essential intervention measures.

Finally, provisions of clean water, sanitation and hygiene after the flooding to prevent infectious disease outbreaks are also very significant.
