COVID 19 Omicron: The Origin, Presentation, Diagnosis, Prevention and Control

Abstract

Coronaviruses have become a global health threat over the past two decades as their geographical spread has accelerated. Coronavirus disease 2019, also known as COVID-19, is the severe acute respiratory syndrome coronavirus 2 The epidemic caused by (SARS-CoV-2). The first known case was confirmed in Wuhan, China in December 2019, where he has caused two pandemics in the past. Severe acute respiratory syndrome and Middle East respiratory syndrome are followed by the current COVID-19 outbreak in China. The virus originates from a zoonotic source and is spread by direct and contact transmission. Symptoms range from fever to cough, muscle aches to severe respiratory failure. Diagnosis is confirmed by reverse transcriptase-PCR. Treatment of COVID-19 consists primarily of supportive care and mechanical ventilation in critical cases. Prevention strategies, along with successful disease isolation and community containment, play an important role in reducing the spread of the virus among the public. A vaccine has been developed to clear the virus from its host, but it is not yet known whether the vaccine works against the virus's newest subspecies, the Omicron subspecies. This review summarizes the most recent research advances in structure, epidemiology, and etiology. We also focused on mutational patterns, an important feature of viral virology, and examined existing variants, especially its omicron variant. The clinical features of COVID-19, current treatments, and scientific advances to combat the epidemic novel coronavirus were discussed.

Immunological Changes with Age and Innovative Approaches to Bolster Immune Function in Older Adults

Evaluation of the Awareness and Practice of HIV Positive Mothers towards Infant Feeding Options at Serere Health Center IV, Serere District

“…The Joint United Nations Program on HIV/AIDS (UNAIDS) and two of its partners (UNICEF and WHO) recommended that HIVinfected mothers should avoid breastfeeding only when replacement feeding was affordable, feasible, acceptable, sustainable, and safe (AFASS). Non breast-fed children born to HIV positive women were at less risk of illness and death only if they could be ensured uninterrupted access to nutritionally adequate breast milk substitutes that were safely prepared [23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Exclusive replacement (formula) feeding was the most widely used and effective method to prevent MTCT of HIV-1 through breastfeeding in resource-rich settings and was recommended in situations in which this was AFASS [37].…”

Ugandan Pregnant and New Mothers’ Perceptions, Knowledge, and Information Sources on COVID-19 at Jinja Regional Referral Hospital

“…Early scenarios of the COVID-19 pandemic often depicted waves, including a possible second wave in late 2020. By the end of August, countries around the globe had reported over 25 million cases, with nearly 850,000 deaths attributed to the disease [15][16][17][18][19]. Since the outbreak of the novel coronavirus disease (COVID-19), which was first reported in Wuhan, China, on December 31, 2019, there has been a steep increase in the numbers of confirmed cases, deaths, and affected countries.…”

“…Since the outbreak of the novel coronavirus disease (COVID-19), which was first reported in Wuhan, China, on December 31, 2019, there has been a steep increase in the numbers of confirmed cases, deaths, and affected countries. According to the World Health Organisation (WHO), it took more than three months to reach the first 100,000 confirmed cases, 12 days to reach the next 100,000cases, 4 days to reach 300,000 cases, and only 3 days to reach 400,000 cases [20][21][22].…”
