ABSTRACT
The current monkeypox outbreak is a public health emergency of international concern and is coming in the wake of the SARS-CoV-2 pandemic. Human monkeypox is a viral zoonotic infection caused by monkeypox virus, an enveloped double-stranded DNA virus of the genus Orthopoxvirus and family Poxviridae that also contain smallpox, cowpox, Orf, and vaccinia viruses. Online databases including PubMed, Google Scholar and Web of Science were searched to obtain relevant publications on the epidemiology, treatment, vaccines and the economic impacts of the current monkeypox (Mpox) outbreak.
ABSTRACT
Background: COVID-19 is a major global health challenge that has affected all age groups and gender, with over 5 million deaths reported worldwide to date. The objective of this study is to assess available information on COVID-19 in children and adolescents with respect to clinical characteristics, co-morbidities, and outcomes, and identify gaps in the literatures for appropriate actions. Methodology: Electronic databases including Web of Science, PubMed, Scopus, and Google Scholar were searched for observational studies such as case series, cross-sectional and cohort studies published from December 2019 to September 2021, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guide. Data extracted included (i) patient demography (age and gender), (ii) clinical characteristics including vaccination status and presence of co-morbidities, (iii) clinical management including the use of sequential organ failure assessment (SOFA) scores, oxygen requirement, use of mechanical ventilation, and (iv) disease outcomes including length of hospital and intensive care unit (ICU) admission, recovery, complications with sequelae, or death. Data were analyzed using descriptive statistics. Result(s): A total of 11 eligible studies were included with a total of 266 children and adolescents;137 (51.5%) females and 129 (48.5%) males. The mean age of the children was 9.8 years (range of 0 - 19 years), and children >= 6 years were more affected (40.7%) than age groups 1 - 5 years (31.9%) and < 1 year (27.4%). The major co-morbidities were respiratory diseases including pre-existing asthma (3.4%), neurologic conditions (3.4%) and cardiac pathology (2.3%). Majority (74.8%, 199/266) of the patients were discharged without sequelae, 0.8% (2/266) were discharged with sequalae from one study, and mortality of 1.9% (5/266) was reported, also from one study. SOFA scores of patients at admission were not stated in any of the study, while only one study reported patient vaccination status. Conclusion(s): It is recommended that safe vaccines for children < 1 year of age should be developed in addition to other preventive measures currently in place. SOFA scores should be used to assess risk of COVID-19 severity and monitor prognosis of the disease, and vaccination status of children should be documented as this may impact the management and prognosis of the disease.

ABSTRACT
SARS-CoV-2 has evolved over time with several mutations, especially on the spike protein, which has led to emergence of various variants. With the evolution of SARS-CoV-2 come new challenges in surveillance, effectiveness of preventive and treatment strategies, and outcome of the disease. Despite the lockdowns, mask mandates and other preventive measures put in place, in addition to over 10 million vaccine doses that have been administered globally as of February 2022, COVID-19 cases have risen to over 435 million and resulted in over 5.9 million deaths, largely as a result of the evolution of SARS-CoV-2 variants. To review the evolution of these variants, we searched different online database sources using keywords such as “source of SARS-CoV-2”, “SARS-CoV-2 origin”, “evolution of SARS-CoV-2”, “SARS-CoV-2 variants”, “variants of concern”, “variants of interest”, and “variants of high consequence”. This was to enable us give a good report about the various variants of SARS-CoV-2 that have emerged so far, and the public health challenges posed by them.
