STATISTICAL ANALYSIS FOR INFECTIONS OF MALARIA IN THE RIVER NILE STATE(SUDAN) (2018-2022)

Abstract

This article analyzes malaria cases in River Nile State (Sudan) during the period 2018-2022. It concludes that Malaria prevalence rates in River Nile State (Sudan) were very similar across the study years (2018-2022), reaching 17%, 16%, 15%, 14%, and 13%, respectively. This is very high compared to the global malaria prevalence rate (3.1%), but close to the African average (16.4%). There is a significant difference in malaria cases across the years. Due to the increase in the number of cases in recent years, there is no significant difference in cases between months during each study year, meaning that cases are similar throughout the year. However, cases increase in winter and decrease in summer, cases increased for all months in 2022 compared to 2018, especially in April, except for June and July, where they decreased by 3% and 8%. Overall infections increased by 27.6% from 2018 to 2022 and the predictive values showed an increase in the number of infections over the next five years. The article recommends that there should be an increase in mosquito control measures, especially during the winter months. Mosquito nets be provided, especially to those living in rural areas. They must be educated about water conservation. Necessary treatment be provided to reduce the number of deaths and study the reasons that led to the sharp rise in April 2022.
