Corona Virus Strain
The mutated coronavirus strain that’s been spreading in the U.K. , Africa and other parts of Europe appears to be more contagious and variant is 56% more transmissible than other strains, according to the study by the Centre for Mathematical Modelling of Infectious Diseases at the London School of Hygiene and Tropical Medicine. In medical terms, a strain is a genetic variant, or a subtype within a biological species. Strains are often seen as inherently artificial concepts, characterized by a specific intent for genetic isolation. Human Coronavirus Types: Scientists have divided coronaviruses into four sub-groupings, called alpha , beta , gamma , and delta . Seven of these viruses can infect people: 229E (alpha) NL63 (alpha) OC43 (beta) HKU1 (beta) MERS-CoV, a beta virus that causes Middle East respiratory syndrome (MERS) SARS-CoV, a beta virus that causes severe acute respiratory syndrome (SARS) SARS-CoV-2, which cau
