As of 23 March 2020, more than 1.2 billion learners were out of school due to school closures in response to COVID-19. [8] Given low rates of COVID-19 symptoms among children, the effectiveness of school closures has been called into question. [13] Even when school closures are temporary, it carries high social and economic costs. [14]
Many point-of-care test systems are realized as easy-to-use membrane-based test strips, often enclosed by a plastic test cassette. [2] This concept often is realized in test systems for detecting pathogens, the most common being COVID-19 rapid tests. Very recently such test systems for rheumatology diagnostics have been developed, too. [12]
The Periodontal Screening and Recording (PSR) is increasingly used in the United States, Canada and Brazil. The Basic Periodontal Examination (BPE) is extensively used in the United Kingdom and New Zealand. The Primary Essential Periodontal Examination (PEPE) is used in Australia.

COVID-19 rapid antigen tests or RATs, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-CoV-2 infection . They are quick to implement with minimal training, cost a fraction of other forms of COVID-19 testing , and give users a result within 5–30 minutes.
The WHO did not offer any test kits to the U.S. because the U.S. normally had the supplies to produce their own tests. [3] The United States had a slow start in widespread SARS-CoV-2 testing. [4] [5] From the start of the outbreak until early March 2020, the CDC gave restrictive guidelines on who should be eligible for COVID-19 testing. The ...
A new portable test that detects coronavirus infection within a four-minute window has been developed by scientists in Shanghai. The test is reportedly as accurate as a polymerase chain reaction ...
