What is the prevalence of HTPs in Nigeria?

Introduction

The prevalence of various human transmissible pathogens (HTPs) such as Hepatitis B Virus (HBV), Human Immunodeficiency Virus (HIV), and Human Papillomavirus (HPV) in Nigeria is a significant public health concern. Understanding the distribution and factors associated with these infections is crucial for developing effective prevention and control strategies.

Key Insights

Hepatitis B Virus (HBV) Prevalence:
- The prevalence of HBV infection in the general population of Nigeria is 12.2%.
- Among HIV-positive patients, the prevalence of HBV surface antigen (HBsAg) is 9.7%.
Human Immunodeficiency Virus (HIV) Prevalence:
- The prevalence of HIV-1 and HIV-2 infections in Nigeria is 2.0% and 1.3%, respectively.
- The highest prevalence rates are observed among female prostitutes (10% for HIV-1 and 6.7% for HIV-2) and patients with sexually transmitted diseases (4.1% for HIV-1 and 3.4% for HIV-2).
Human Papillomavirus (HPV) Prevalence:
- The overall prevalence of HPV among urban Nigerian women is 37%.
- The prevalence of HPV is highest among women aged ≤30 years (52%) and decreases with age, with only 23% of women older than 45 years being infected.

Conclusion

The prevalence of HTPs in Nigeria is notably high, with HBV affecting 12.2% of the general population and 9.7% of HIV-positive individuals. HIV-1 and HIV-2 infections have a combined prevalence of approximately 3.3%, with higher rates among high-risk groups such as female prostitutes and patients with sexually transmitted diseases. HPV infection is prevalent in 37% of urban Nigerian women, with younger women showing higher infection rates. These findings underscore the need for targeted public health interventions and improved vaccination and screening programs to control the spread of these infections in Nigeria.
