ABSTRACT

The article reports on the beginning of the Coronavirus disease pandemic (COVID-19). It highlights the research finding which says that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not originated from China. It mentions that China has not allowed foreign researchers to conduct independent origin studies in the country and United States President Joseph Robinette Biden criticized the World Health Organization report.

ABSTRACT

The article discusses the clinical trials of new mRNA vaccines to combat COVID-19 that will be easier to store and cheaper, including one from China in a phase 3 trial. Vaccines produced by the Pfizer-BioNTech and Moderna rely on mRNA to direct cells to produce spike, a protein on SARS-CoV-2's surface, which are of high price and need to be stored at extremely low temperatures.

ABSTRACT

The article offers information on Supaporn Wacharapluesadee, who hunts for viruses to understand and prevent pandemic threats. She tracked the Nipah virus, a bat-borne pathogen, and her quest had gained new importance during the COVID-19 pandemic, which originated when a bat coronavirus evolved into SARSCoV-2 and crossed over into humans. She sampled "Rhinolophus" to find a clue to SARS-CoV-2's origin.

ABSTRACT

COVID-19 testing provides information regarding exposure and transmission risks, guides preventative measures (e.g., if and when to start and end isolation and quarantine), identifies opportunities for appropriate treatments, and helps assess disease prevalence (1). At-home rapid COVID-19 antigen tests (at-home tests) are a convenient and accessible alternative to laboratory-based diagnostic nucleic acid amplification tests (NAATs) for SARS-CoV-2, the virus that causes COVID-19 (2-4). With the emergence of the SARS-CoV-2 B.1.617.2 (Delta) and B.1.1.529 (Omicron) variants in 2021, demand for at-home tests increased† (5). At-home tests are commonly used for school- or employer-mandated testing and for confirmation of SARS-CoV-2 infection in a COVID-19-like illness or following exposure (6). Mandated COVID-19 reporting requirements omit at-home tests, and there are no standard processes for test takers or manufacturers to share results with appropriate health officials (2). Therefore, with increased COVID-19 at-home test use, laboratory-based reporting systems might increasingly underreport the actual incidence of infection. Data from a cross-sectional, nonprobability-based online survey (August 23, 2021-March 12, 2022) of U.S. adults aged ≥18 years were used to estimate self-reported at-home test use over time, and by demographic characteristics, geography, symptoms/syndromes, and reasons for testing. From the Delta-predominant period (August 23-December 11, 2021) to the Omicron-predominant period (December 19, 2021-March 12, 2022)§ (7), at-home test use among respondents with self-reported COVID-19-like illness¶ more than tripled from 5.7% to 20.1%. The two most commonly reported reasons for testing among persons who used an at-home test were COVID-19 exposure (39.4%) and COVID-19-like symptoms (28.9%). At-home test use differed by race (e.g., self-identified as White [5.9%] versus self-identified as Black [2.8%]), age (adults aged 30-39 years [6.4%] versus adults aged ≥75 years [3.6%]), household income (>$150,000 [9.5%] versus $50,000-$74,999 [4.7%]), education (postgraduate degree [8.4%] versus high school or less [3.5%]), and geography (New England division [9.6%] versus West South Central division [3.7%]). COVID-19 testing, including at-home tests, along with prevention measures, such as quarantine and isolation when warranted, wearing a well-fitted mask when recommended after a positive test or known exposure, and staying up to date with vaccination,** can help reduce the spread of COVID-19. Further, providing reliable and low-cost or free at-home test kits to underserved populations with otherwise limited access to COVID-19 testing could assist with continued prevention efforts.
