International Research in Medical and Health Sciences en-US International Research in Medical and Health Sciences 2581-771X Asymptomatic Covid-19: A Model Kit <p>Actions on asymptomatic SARS-CoV-2 infections are a fundamental piece of a "model kit" against COVID-19. It has been claimed that up to 40% of infections can be asymptomatic. Without a doubt, the transmission of SARS-CoV-2 from people without symptoms contributes to the spread of the pandemic acting as a "silent driver." Presymptomatic and asymptomatic transmission significantly reduces the effectiveness of control measures that start with the onset of symptoms, such as isolation and follow-up of contacts. In a community transmission scenario, what is desired is to know is whether a patient is contagious. The antigen test is the most powerful tool we have to find out it. So, the focus of testing programs for SARS-CoV-2 should be expanded to include people who do not have COVID-19 symptoms. It is not clear whether the screenings performed so far have worked well, but it is possible that in the coming months the efficacy of the use of antigens for mass testing will improve. Even antigen tests can have an individual use; almost a home use. Having cheap, fast, and self-executing antigens, they may become mandatory for risky activities: traveling by plane, dining in a restaurant, or hanging out with a group of friends for a few days.</p> Jose Luis Turabian Copyright (c) 2021 International Research in Medical and Health Sciences 2021-02-06 2021-02-06 4 1 1 7 10.36437/irmhs.2021.4.1.A Corona Prevention and Control- A Preview <p>Coronaviruses are enveloped non-segmented positive-sense RNA viruses belonging to the family Coronaviridae. The human coronavirus infections are mild, the epidemics of the two β-coronaviruses, severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) have caused more than ten thousand cumulative cases in the past two decades. There is a new public health crises threatening the world with the emergence and spread of 2019 novel coronavirus (2019-nCoV). The virus originated in bats and was transmitted to humans through yet unknown intermediary animals in Wuhan, Hubei province in China during the month of December 2019.<sup>1</sup></p> Johnson M Chetty K Copyright (c) 2021 International Research in Medical and Health Sciences 2021-02-09 2021-02-09 4 1 8 22 10.36437/irmhs.2021.4.1.B Prevalence of Hepatitis B and Tuberculosis among People Living with HIV (PLHIV) in Cameroon <p><strong>Introduction: </strong>Hepatitis B and Tuberculosis are leading causes of morbidity and mortality among people living with HIV (Human Immunodeficiency Virus). These infections are on the rise worldwide, particularly in sub-Saharan Africa. The objective of this study was to identify the presence of Hepatitis B virus and Tuberculosis among people living with HIV at the Central Hospital and Jamot Hospital in Yaoundé.</p> <p><strong>Materials and Methods: </strong>This was a cross-sectional hospital-based descriptive study in which blood and sputum samples were collected from randomly selected 362 people living with HIV (September 2017 to March 2018). Bacteriological examination with auramine staining for the detection of Acido Alcohol Resistant Bacilli, was done. This was followed by amplification of the Mycobacterium tuberculosis sequence IS6110 by a Polymerase Chain Reaction and the strips interpreted with the aid of electrophoresis.&nbsp; Serological analysis for the determination of Hepatitis B virus surface antigen was performed with the aid of a rapid diagnostic test.&nbsp; Positive cases were further confirm using an enzyme-linked immunosorbent assay. Data analysis was purely descriptive calculating prevalence and 95% confidence interval using SPSS&nbsp; software version 22.1.</p> <p><strong>Results: </strong>After analysis, we obtained a prevalence of 9.1%&nbsp; for HIV/Tuberculosis co-infection, in which men were predominant with the prevalence of 5.2% against 0.6% in women. A seroprevalence of 13.5% for HIV/Hepatitis B co-infection was obtained, with the female sex being predominant having a prevalence of 7.7% against 5.8% in males.</p> <p><strong>Conclusion: </strong>These results demonstrate the current epidemiological situation of HIV/Hepatitis B and HIV/Tuberculosis co-infections in Cameroon. Thus, these co-infection remain a real public health problem due to the increase in co-morbidity among HIV patients, hence the need for careful and constant monitoring of these infections so as to ensure better management.</p> Kamdem Thiomo Diane Djuidje Ngounoue Marceline Tchinda Fossi Cedric Kenfack Momo Raoul Martin Ndinakie Yakum Ambassa Axel Cyriaque Tsasse Martine Augusta Flore Assam Assam Jean Paul Pr Penlap Beng Veronique Copyright (c) 2021 International Research in Medical and Health Sciences 2021-02-14 2021-02-14 4 1 23 33 10.36437/irmhs.2021.4.1.C
