Viral load, also known as viral burden, is a numerical expression of the quantity of virus in a given volume of fluid, including biological and environmental specimens. It is not to be confused with viral titre or viral titer , which depends on the assay.
Multisystem inflammatory syndrome in children (MIS-C), or paediatric inflammatory multisystem syndrome (PIMS / PIMS-TS), or systemic inflammatory syndrome in COVID-19 (SISCoV), is a rare systemic illness involving persistent fever and extreme inflammation following exposure to SARS-CoV-2, the virus responsible for COVID-19.

Researchers at the Oswaldo Cruz Foundation published a preprint genomic epidemiology study of 250 collected genomes from different places in Amazonas and found that P.1 infections can produce nearly 10 times more viral load than in other COVID-19-infected persons involving lineages B.1.1.28 and B.1.195. The lineage also showed 2.2 times higher ...
Coronavirus diseases are caused by viruses in the coronavirus subfamily, a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal.
Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
Human-to-human transmission (HHT) is an epidemiologic vector, [1] [2] [3] [4] [5] [6] [7] [8] especially in case the disease is borne by individuals known as ...
Initially called simply novel coronavirus or nCoV, with the provisional names 2012 novel coronavirus (2012-nCoV) and human coronavirus 2012 (HCoV-12 or hCoV-12), it was first reported in June 2012 after genome sequencing of a virus isolated from sputum samples from a person who fell ill in a 2012 outbreak of a new flu-like respiratory illness.
The transmission of COVID-19 is the passing of coronavirus disease 2019 from person to person. COVID-19 is mainly transmitted when people breathe in air contaminated by droplets/aerosols and small airborne particles containing the virus. Infected people exhale those particles as they breathe, talk, cough, sneeze, or sing.
