Background: Mathematical models reflecting the epidemiological dynamics
of dengue infection have been discovered dating back to 1970. The four serotypes
(DENV-1 to DENV-4) that cause dengue fever are antigenically related but
different viruses that are transmitted by mosquitoes. It is a significant global
public health issue since 2.5 billion individuals are at risk of contracting the
virus. Methods: The purpose of this study is to carefully examine the
transmission of dengue with a time delay. A dengue transmission dynamic model
with two delays, the standard incidence, loss of immunity, recovery from
infectiousness, and partial protection of the human population was developed.
Results: Both endemic equilibrium and illness-free equilibrium were
examined in terms of the stability theory of delay differential equations. As
long as the basic reproduction number (
