To check emerging and re-emerging infectious diseases, particularly Viral Hemorrhagic Fevers, which are common in Nigeria, there is the need to screen febrile patients with improved diagnostics, vaccines, and treatment.
Enhancing surveillance systems to effectively control and manage the diseases is also necessary.
A Director of Research and Deputy Director General of the Nigerian Institute of Medical Research, NIMR, Professor Rosemary Audubon, made that call during a chat with newsmen in Lagos.
Professor Audu said research findings revealed that, in Nigeria, Lassa fever remains a major public health issue because in February this year, " the Nigeria Centre for Disease Control and Prevention (NCDC) reported 413 cases and 80 deaths across 11 states and 63 local government areas ".
According to her, " Between 2021 and 2024, dengue, Zika, yellow fever, and chikungunya viruses were detected in febrile patients in Oyo and Delta states, a result she described as surprising
“And in Ondo State, we confirmed the endemicity of Lassa fever, yet 80 percent of suspected cases tested negative, raising concerns about undiagnosed infections,” she said.
“In Delta State, yellow fever virus was detected in mosquito pools even after fumigation, questioning the efficacy of control measures”
Studies on Crimean-Congo hemorrhagic fever in Kwara State provided insights into its prevalence among herdsmen and febrile patients.
Sequencing Nigeria’s first SARS-CoV-2 case in 2020 and conducting seroprevalence studies across multiple states, providing critical data on COVID-19’s spread, was part of her research.
" Between 2021 and 2024, the team detected dengue, Zika, yellow fever, and chikungunya viruses in febrile patients across Oyo and Delta states ". Audu
On its impact on Public health,
Mrs Audu observed that the detection of multiple viral infections in Nigerian communities indicates active transmission, hence the need for interventions.
" Our research confirms the need for intensified efforts to control both rodent and mosquito populations,” she said
“We also need to enhance diagnostic capabilities for VHFs and raise awareness among healthcare providers to improve case detection.”
Professor Audu, who stressed the importance of public knowledge in disease detection and prevention, warned health workers to treat every fever with suspicion because many febrile illnesses in Nigeria are mistaken for malaria and typhoid:"
Despite the numerous breakthroughs, Mrs Audu noted that NIMR faces several challenges, including limited funding, irregular sampling, and the high cost of serology kits.
She explained that the institute is exploring additional grant opportunities and increasing fieldwork engagement among postgraduate researchers to address the issues having been given the mandate.
Looking ahead, she said NIMR aims to expand VHF surveillance to more states, develop improved diagnostics and vaccines, and evaluate the effectiveness of available Mpox vaccines for Nigerian strains.
“Understanding the diversity of infectious agents will improve disease control and guide better public health decisions,” she said.
“Our findings have been shared at national and international scientific conferences, and we remain committed to collaborating with policymakers to implement effective health strategies.”
Earlier, the Director-General of the Institute, Professor NIMR John Obafunwa, again complained of the electricity situation in the Institute, expressing dismay that the dwindling power supply and the threat of disconnection by the PHCN was a huge challenge as research equipments are temperature sensitive.
He explained that for NIMR to perform optimally and take its pride of place in research and production of test kits, especially to Viral Hemorrhagic Fevers, government and well-meaning individuals should support the Institute to ensure sustainability.
The Forensic Pathology expert stressed the importance of early and accurate disease diagnosis, citing inadequate diagnostic tools and the high costs of medical reagents as some of the challenges.
" The increasing presence of Aedes aegypti mosquitoes as explained by Professor Audu could increase the spread of arboviral diseases if left unchecked hence the need to act fast ". Obafunwa warned.
