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. …

A Decade of Viral Evolution (2015–2025): Emergence, Mutations, and Implications for Global Health
Abstract: Over the past decade (2015-2025), viral evolution has profoundly reshaped the global health landscape, challenging healthcare systems, diagnostic tools, therapeutic strategies, and vaccine efficacy. This review comprehensively analyzes the evolutionary trajectories of major human and zoonotic viruses, with a focus on pandemic-prone, drug-resistant, and emerging pathogens. Viral evolution is driven by diverse molecular mechanisms including high mutation rates, recombination, reassortment, host immune pressure, and antiviral interventions, leading to genetic diversification, …

In Silico Assessment of Demethoxycurcumin: Molecular Docking and Computational Insights into its various therapeutic Potential
Abstract: Natural compounds are increasingly explored for their therapeutic potential in medical research. Here, we focused on demethoxycurcumin (DMC), a polyphenolic bioactive compound extracted from Curcuma longa, commonly found in turmeric. DMC, with a chemical formula of C20H18O5 and a molecular weight of 340 g/mol, possesses two aromatic ring systems, each featuring a β-diketone moiety connected by a seven-carbon chain. This unique structure allows DMC to engage in tautomerism, which is …

Vaccines in the Fight Against COVID-19: Mechanisms, Efficacy, and Global Challenges
Abstract: The SARS-CoV-2 pandemic has created an unparalleled public health problem, necessitating comprehensive prevention. This page discusses COVID-19's evolution, scientific understanding, and quick vaccine production and implementation. It compares the mechanisms, efficacy, and safety profiles of the four major types of COVID-19 vaccines—namely mRNA, viral vector, protein subunit, and inactivated virus vaccines. Each type is evaluated in terms of how it stimulates the immune response, its effectiveness in preventing infection or …

Description & Prevention of Omicron
Abstract: November 9, 2021, Botswana becomes the first country to recognise it (Nov 11 2021). The new variant (B.1.529) has been represented in 77 countries. Omicron presents 32 changes in spike protein Scribd, restricting the point of interaction with the ACE2 receptor protein. Computational shows and components’ recreation has been applied to investigate the collaboration between the SARS-CoV-2 RBD and the ACE2 receptor. The receptor-binding domain (RBD), which more barely joins …

COVID-19 Resurgence in 2025: India’s Continuing Public Health Challenge
Abstract: The year 2025 has witnessed the resurgence of COVID-19, reigniting concerns at both global and national levels regarding the persistent threat posed by SARS-CoV-2. In early 2025, India witnessed a moderate resurgence of COVID‑19, characterized by the emergence of Omicron sub-variants and a rise in mild-to-moderate infections. As of mid-June, active COVID‑19 cases in India totaled approximately 6,000–7,400, with hotspots in Kerala (~2,100 cases), Delhi (~600), Maharashtra (~500), and several …

Live Epidemiological Tracking of COVID-19 in Senegalese Participants of the Hajj
Abstract: Background: Since the COVID-19 outbreak, global efforts have focused on controlling the disease. However, intense cross border movements pose a risk for the emergence of new SARS-CoV-2 strains. A recent example is the detection of cases among the 2024 Senegalese pilgrims returning from Mecca, Saudi Arabia. Investigations of these cases have revealed genomic evolution of the virus. The lack of surveillance may lead to the emergence of high-threat strains. This …

Viral Chronicles: The Ever-Evolving Saga of COVID-19
Abstract: Coronaviruses, belonging to the family of RNA viruses, have recently captured global attention owing to their remarkable ability to infect a diverse array of species, ranging from animals to humans. These viral agents, recognized by their characteristic crown-like morphology when observed through electron microscopy, have a historical association with zoonotic diseases. Previous examples include Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and Middle East Respiratory Syndrome Coronavirus (MERS-CoV). The term "Corona" …

Mid-Year Epidemiological Profile of COVID-19 Posi ve Cases in Rajasthan, India
Abstract: Background: COVID-19, caused by SARS-CoV-2, has posed persistent public health challenges globally since its emergence in late 2019. India, through enhanced surveillance and vaccina on, has seen a progressive decline in case burden. Despite improvements, localized surges and emerging variants necessitate con nuous monitoring. Rajasthan, with its urban-rural health dispari es, experienced a modest resurgence of cases in early 2025, raising concerns about exis ng immunity gaps and health system …

Targeting Papain-Like Protease of Re-Emerging Coronaviruses
Abstract: Re-emerging Corona viruses (CoVs), including SARS-CoV (S-CoVs), and SARS-CoV-2 (S-CoV-2), continue to pose a global health threat due to their high mutation rates, zoonotic spillover potential, and capacity for immune evasion. The global pandemic of year 2019, caused by S-CoV-2, has highlighted the importance for robust antiviral strategies beyond vaccines and RNA polymerase or main protease inhibitors, which are susceptible to resistance. One promising therapeutic target is the S-CoV-2 papain-like …
