Nigeria is facing a growing public health concern as new research reveals alarmingly high levels of multidrug-resistant typhoid fever, particularly in communities with poor sanitation and limited access to clean water. The findings raise fears over shrinking treatment options and the risk of more severe outbreaks if urgent interventions are not implemented.
The study, conducted by researchers at the Trans-Saharan Diseases Research Centre, Ibrahim Badamasi Babangida University, examined the prevalence of typhoid fever and antibiotic resistance patterns in Niger State. The location was selected due to persistent challenges with sanitation and healthcare access, conditions common in many parts of the country.
Using a cross-sectional design, researchers analysed stool samples from adults aged 18 years and above to detect Salmonella enterica serotype Typhi, the bacterium responsible for typhoid fever. Laboratory results showed widespread resistance to several commonly prescribed antibiotics. Older, widely available drugs—including Amoxicillin—were found to be largely ineffective, while newer medications such as Levofloxacin and Gentamicin showed only moderate effectiveness.
The findings highlight antimicrobial resistance as a major factor worsening Nigeria’s typhoid burden. With millions of cases reported annually across sub-Saharan Africa, Nigeria’s situation is becoming increasingly difficult as treatment options diminish. Researchers linked this trend to the misuse of antibiotics and their easy over-the-counter availability, which accelerates resistance and raises treatment costs.
Environmental and behavioural factors were also significant. Higher infection rates were recorded among individuals relying on public tap water compared to those using boreholes, pointing to contamination within water supply systems. Poor hygiene practices and overcrowded living conditions further increased exposure, with young adults aged 18 to 27 identified as the most affected group.

Health experts warn that poorly treated typhoid fever can lead to serious complications, prolonged hospitalisation, and increased mortality. The rise of multidrug-resistant strains heightens the risk of treatment failure and places additional strain on Nigeria’s already overstretched healthcare system.
To address the growing threat, the study calls for urgent investment in water, sanitation, and hygiene infrastructure, alongside stricter regulation of antibiotic sales and use. Public health education to discourage self-medication and promote early medical care is also critical. Researchers further recommend sustained disease surveillance to track resistance patterns and guide evidence-based treatment.
Without coordinated action from government, healthcare providers, and communities, experts warn that Nigeria risks a wider public health crisis driven by the dual challenge of typhoid fever and antimicrobial resistance.
