Exploring the influence of burial and cremation practices on Nipah virus transmission: a SIRD model analysis

This paper proposes a SIRD model to investigate the impact of burial or cremation practices on the transmission dynamics of the Nipah virus, which is highly fatal and can spread rapidly through communities via contact with deceased bodies. An analysis is conducted to determine the stability of the disease-free and endemic equilibria and to compute the reproduction number. A comprehensive sensitivity analysis of the reproduction number is conducted to assess the effectiveness of different control measures. It has been found that avoiding unnecessary contact with infected or buried/cremated bodies can greatly reduce the transmission of viruses. Aditionally, an investigation is conducted on the stability conditions of Hyers–Ulam and Hyers–Ulam–Rassias, discuss existence and uniqueness conditions, and verify theoretical findings via MATLAB-based numerical simulations presenting graphical representations of the data. This analysis provides insightful information about potential treatments to slow the spread of the Nipah virus.
