Steps in Outbreak Investigation

107
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Summary
This summary is machine-generated.

Lassa fever (LF) outbreaks in Nigeria from 2020-2023 caused significant illness and death. Poor knowledge of LF prevention and transmission affects risk perception, highlighting the need for public health campaigns.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Epidemiology

Background:

  • Lassa fever (LF) poses an annual public health threat in Nigeria and Sub-Saharan Africa due to zoonotic spillover from endemic rodent populations.
  • The Lassa Virus (LASV) causes significant morbidity and mortality during annual outbreaks.

Purpose of the Study:

  • To review the burden of Lassa fever in Nigeria between 2020 and 2023.
  • To evaluate the risk perceptions of Lassa fever among Nigerians.

Main Methods:

  • A review of Lassa fever cases in Nigeria from 2020-2023.
  • A cross-sectional survey of 2,150 Nigerian participants to assess knowledge and risk perception of LF.

Main Results:

  • Between 2020-2023, Nigeria reported 28,780 suspected and 4,036 confirmed LF cases, with 762 deaths (18.9% CFR).
Rodent
  • 35.43% of aware participants had poor knowledge of LF prevention and transmission.
  • Higher education correlated with better LF knowledge and lower risk, while poor risk perception increased LF contraction likelihood.

    • Conclusions:

    • Significant knowledge gaps regarding Lassa fever prevention and transmission persist in Nigeria.
    • Improving LF diagnostics, infection control, and public awareness campaigns are crucial for mitigating LF impact.
    • Implementing a One Health approach is essential for controlling LASV from animal reservoirs.
