"Secondary Attack Rate". Epiville - Columbia University Mailman School of Public Health. เก็บ จากแหล่งเดิมเมื่อ 2020-12-08. สืบค้นเมื่อ 2021-07-13. Secondary attack rate refers to the spread of disease in a family, household, dwelling unit, dormitory, or similar circumscribed group. The spread of infection from an index case (the initial case, i.e. the case that introduced the organism into the population) to the attending medical staff is called secondary attack rate.

Though these mutations have individually been found in several other coronavirus variants, the presence of both these mutations together have been first found in some coronavirus genomes from India.

Collectively, our study reveals that antibody evasion of B.1.617 may contribute to the rapid spread of this variant... ...The RBD of the B.1.617 S protein harbors two mutations associated with (L452R) or suspected (E484Q) of antibody evasion... ...Moreover, E484K present the B.1.351 and P.1 variants confers antibody resistance (Li et al., 2021) and one could speculate that exchange E484Q might have a similar effect.

World Health Organization. p. 26. hdl:10665/70863. WHO/CDS/CSR/GAR/2003.11. A number of researchers have estimated the basic reproduction number by fitting models to the initial growth of epidemics in a number of countries. Their observations indicate that the SARS-CoV is less transmissible than initially thought with estimates of Ro in the range of 2-4.
