The US CDC's COVID-19 laboratory test kit. COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2, the virus that cases COVID-19 and is responsible for the COVID-19 pandemic. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection.
COVID-19 is considered by scientists to be "of probable animal origin". [45] It has been classified as a zoonotic disease (naturally transmissible from animals to humans). Some scientists dispute this classification, since a natural reservoir has not been confirmed.
The European Centre for Disease Prevention and Control (ECDC) also list a fourth spike mutation of interest: [14] D614G. This is a substitution at position 614, an aspartic acid-to-glycine substitution. [15] Other variants which have the D614G mutation include the Beta and Delta variants, and the mutation is associated with increased ...
The Gamma variant (P.1) [a] was [6] [7] one of the variants of SARS-CoV-2, the virus that causes COVID-19. [8] This variant of SARS-CoV-2 has been named lineage P.1 and has 17 amino acid substitutions , ten of which in its spike protein, including these three designated to be of particular concern: N501Y , E484K and K417T.
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.
Around the globe, a new strain of COVID-19 is spreading exponentially. The COVID-19 XEC variant is derived from Omicron strains KS.1.1 and KP.3.3, ... More: Free COVID-19 tests are now available ...
The development of COVID-19 tests was a major public health priority during the early months of the COVID-19 pandemic. In January 2020, scientists from China published the first genetic sequences of SARS-CoV-2 via virological.org, [3] a "hub for prepublication data designed to assist with public health activities and research". [4]
Two lines appear on the test card, 15 minutes after you’ve swabbed the depths of your nostrils and swirled the contents in a plastic tube.You’ve got COVID. As recently as February, a positive ...
