The unique features of the human immunodeficiency virus (HIV) envelope protein have
thwarted efforts to identify a protective vaccine. However, a vaccine that does not prevent …

In this paper, a homogeneous-mixing population fractional model for human
immunodeficiency virus (HIV) transmission, which incorporates anti-HIV preventive …

This paper presents a deterministic model for dengue virus transmission. The model is
parameterized using data from the 2017 dengue outbreak in Pakistan. We estimated the …

A deterministic model for the transmission dynamics of a strain of dengue disease, which
allows transmission by exposed humans and mosquitoes, is developed and rigorously …

The phenomenon of backward bifurcation in disease transmission models, where a stable
endemic equilibrium co-exists with a stable disease-free equilibrium when the associated …

This paper addresses the synergistic interaction between HIV and mycobacterium
tuberculosis using a deterministic model, which incorporates many of the essential …

This paper provides a rigorous mathematical study for assessing the dynamics of smoking
and its public health impact in a community. A basic mathematical model, which is a slight …

This guide was developed to help meet the need of decision-makers for relevant, reliable
and consistent economic information; it aims to provide clear and concise, practical, high …

Multiple effective vaccines are currently being deployed to combat the COVID-19 pandemic,
and are viewed as the major factor in marked reductions of disease burden in regions with …

A new non-autonomous model is designed and used to assess the impact of variability in
temperature and rainfall on the transmission dynamics of malaria in a population. In addition …
