Epidemiology Study - Overview

COVID 19 Study Objective:

To determine the prevalence and incidence of COVID 19 among individuals in a defined population. This objective outlines the primary aim of the study, which is to establish the frequency of COVID 19 within a specific age group and geographic area, while also seeking to understand potential factors contributing to its development. Moreover, the report is having geographic coverage including North America, Europe and rest of the world however customisation can be made in the geographic coverage.

COVID 19 Study USP:

• This epidemiological study on COVID 19 stands out due to its comprehensive approach in establishing precise prevalence rates, identifying novel risk factors, and exploring geographical variations in a diverse population.
• By integrating advanced imaging techniques with robust statistical analyses, the study aims to provide actionable insights to identify treatment opportunities, target population, and an overview on public health initiatives aimed at mitigating the impact of COVID 19 related health problems.
• Through meticulous data collection and rigorous methodology, the study not only contributes to the scientific understanding of COVID 19 but also serves as a foundation for future research events and healthcare policymaking in addressing this increasing COVID 19 cases.

COVID 19 study summary:

COVID 19 study summarizes the prevalence, incidence, possible risk factors, and geographic variations of the COVID 19 worldwide.

COVID 19 Disease overview:

Covid 19 is a respiratory illness caused by SARS-CoV-2 Virus. First identified in Wuhan China in 2019, it quickly became a global pandemic, leading to significant health, social, and economic impacts worldwide. Transmission is primarily through respiratory droplets, also via surfaces and aerosols in closed spaces. Symptoms include fever, cough, fatigue, loss of smell/ taste, sore throat, shortness of breath. Different variants of concern of covid 19 include Alpha, Beta, Gamma, Delta, Omicron, and subvariants.

As of April 2023, the World Health Organization (WHO) has recorded a total of 762,791,152 confirmed COVID-19 cases worldwide, along with 6,897,025 reported deaths. The global death toll stood at around 6.88 million. While global reporting has decreased the world health organisation (WHO) continues to monitor situation through COVID-19 dashboard.

Certain tests available in the market for the Diagnosis Of Covid 19 are as Follows PCR Tests, Antigen Tests, Antibody Tests, CRISPR Tests. Key market players manufacturing the diagnostic kits for covid 19 detection include Abbott Laboratories, Hologic, BD, Thermo Fisher Scientific, Meridian Bioscience, Mesa Biotech, Lucira Health, GenMark Diagnostics, Danaher Corporation, HoffmannLa Roche, Qiagen, PerkinElmer, BioNTech, Siemens Healthineers.

May 2025, A new wave of COVID-19 cases is spreading across parts of Asia, particularly in Singapore, Hong Kong, and Thailand, driven by the Omicron subvariant JN.1. In India, 257 active cases have been reported, mainly in Kerala, Maharashtra, and Tamil Nadu, though JN.1 has not been officially confirmed. JN.1, a descendant of the BA.2.86 (Pirola) lineage, has multiple mutations that may enhance immune evasion but does not appear to cause more severe illness. Symptoms are similar to other Omicron strains, including fever, cough, fatigue, and sore throat. The WHO classifies JN.1 as a "variant of interest" and states that current vaccines remain effective in preventing severe disease and death.

COVID 19 Demographic and Environmental Risk Factors:

Age and Sex:  covid 19 affects individuals of all age group, however older adults particularly those above aged 65 and above are at higher risk of severe illness, hospitalization and death. In a study conducted in 13 countries the highest population of deaths was consistently observed in oldest age groups ranging 80 t0 90 and more.  Globally man have slightly higher risk of being diagnosed with covid 19 compared to women, a meta-analysis revealed that men have 8% higher risk of infection than women. As per PubMed Central report incidence with age distribution was 31.9% for 65 to 79 years age range, 29.6% for those aged 50 to 64 years, 16.3% for those older than 79.

Ethnicity: According to PubMed Central, a study of nearly 99,000 hospitalised patients found that Hispanics constituted 36.2% cases, blacks with 13.1 %, and whites with 42.6% cases in United States. According to the reports of TIMES, in United Kingdom, black Africans had 3.24 times higher risk of death, Bangladeshis with 2.41 times, black Caribbeans had 2,21 times and Indians with 1,7 times higher risk of death from covid 19.

Risk Factors causing COVID 19: Individuals aged 60 and more were having highest risk of getting affected with the infection, pre existing health conditions like cardiovascular disease, Diabetes, chronic respiratory disease, Cancer( low immunity), obesity further trigger the chances of getting infection, lack of vaccination or incomplete vaccination make people more prone to covid 19, people ling in high population density areas or exposure air pollution can be another risk factor, people who are mostly likely to get affected are those working in factories, healthcare providers, public transport operators etc.

COVID 19 Market Scope:

Drivers: The persistent rise in COVID-19 cases, particularly with new variants emerging, is a significant driver for the COVID-19 Diagnostics Market Industry. According to the World Health Organization (WHO), the overall global incidence of COVID-19 has seen fluctuations, with the Delta and Omicron variants causing spikes in cases. For instance, recent reports indicated that over 200 million new cases were documented in 2022 alone. Health authorities worldwide, including the Centers for Disease Control and Prevention (CDC), are emphasizing the need for regular and rapid diagnostic testing to monitor and control outbreaks. This urgency enhances the demand for diagnostic tests, as whole governments, including those from countries such as India and Brazil, are investing heavily in testing infrastructure to manage public health effectively. The implementation of widespread testing campaigns ensures that the market for COVID-19 diagnostics remains robust, catering to both current and future testing needs.

Government Initiatives and Funding Government initiatives focused on healthcare improvement and pandemic response are pivotal drivers of growth in the COVID-19 Diagnostics Market Industry. Various countries have put forth substantial funding; for example, in the United States, the government allocated billions of dollars for COVID-19 testing and diagnostics. The American Rescue Plan Act, which included funding specifically aimed at enhancing testing and contact tracing capabilities, significantly boosted demand for diagnostic products. These initiatives ensure that testing is accessible to the public, thereby increasing the adoption of COVID-19 diagnostic solutions across different demographics.

Restraints: Declining covid 19 case numbers, vaccine hesitancy and misinformation, regulatory barriers leading to delayed product launch, side effects of the treatment are some of the factors which can contribute to hamper the growth of the market involved in developing and manufacturing the vaccines and other therapeutics for the treatment of Covid 19.
