Real Time Characterization of BA.2.86 and Its Variant (JN.1) in Senegal Using Midnight Protocol
Abstract: During the week ending August 13th, 2023, the most prevalent variant of interest (VOI), uploaded to GISAID, was the BA.2.86 variant. This SARS-CoV-2 Omicron lineage was described as the first phylogenetically distinct from the currently circulating SARS-CoV-2 Omicron XBB lineages, including EG.5.1 and HK.3. Compared to the XBB and BA.2 lineages, the BA.2.86 possesses more than 30 mutations in the Spike (S) protein, suggesting a significant potential for immune evasion. …

Host-Pathogen Coevolution: Implications for Immune Evasion and Pathogen Fitness
Abstract: The interaction between hosts and pathogens represents a continuous evolutionary struggle, shaping both microbial virulence and host immunity. Pathogens employ diverse strategies to evade immune surveillance, ranging from antigenic variation and molecular mimicry to hijacking of host immune checkpoints. Simultaneously, hosts refine innate and adaptive immune mechanisms to counteract infection and limit damage. This reciprocal adaptation, known as host–pathogen coevolution, influences pathogen persistence, transmission, and fitness, while also sculpting immune …

Infectious illnesses in areas of violence and among refugees
Abstract: Infectious illnesses are a huge and ongoing hazard in conflict zones and among refugee populations. This is because frail health systems, population relocation, and poor living conditions all come together to make transmission risks higher. Armed conflict undermines vital public health infrastructure, such as vaccination programs, disease surveillance, water and sanitation systems, and access to medical care, resulting in the resurgence and proliferation of avoidable and treatable illnesses. Refugee camps …

The Effects of HIV/AIDS Worldwide
Abstract: The Human Immunodeficiency Virus (HIV), which targets immune system conductors (CD4 cells), has infected millions throughout the world. HIV lowers the body's defences by infecting certain bodily fluids (blood, sperm, vaginal fluids, and breast milk) through unprotected sex, contaminated needles, or mother-to-child transmission. Early flu-like symptoms may go unrecognised, but if not treated, HIV advances to AIDS, which is characterised by severe immune system impairment. However, advances in antiretroviral therapy …

Social Determinant in Health : Epidemiological study of communicable diseases, Demography and Mortality rate.
Abstract: Introduction: Social Determinants of Health (SDH) significantly influence the spread and prevalence of communicable diseases. Factors such as poverty, income inequality, healthcare access, education, employment, location, and social connections shape disease transmission within populations. Additional factors like age, gender, migration, and urbanization further explain the relationship between SDH and public health. Mortality rates, including life expectancy, infant mortality, and access to clean water and sanitation, are deeply affected by these …

Virulence Factors in pathogens :mechanisms of infection & disease progression
Abstract: Pathogens, like bacteria, viruses, fungi, and parasites, have evolved specialized tools – known as virulence factors – that help them infect hosts, escape the immune system, and cause disease. These factors play a key role in determining how severe an infection becomes, how quickly it spreads, and how the body responds. Some pathogens use adhesins to stick to host cells, while others produce toxins that damage tissues or disrupt normal …

A Review on Unmasking Merkel Cell Polyomavirus: From Discovery to Cancer Driver
Abstract: Merkel cell polyomavirus (MCPyV) is a small, non-enveloped, circular double-stranded DNA virus belonging to the Polyomaviridae family, first characterized in 2008. Epidemiological data suggest widespread exposure, with seroprevalence rates approaching 80% in adults. While primary infection is typically asymptomatic, rare integration events in Merkel cells can initiate oncogenesis, yielding Merkel cell carcinoma (MCC), a neuroendocrine skin cancer with a five-year survival rate under 60%. This review integrates findings from six …
