Secondary Transmission of COVID-19 in Households Secondary transmission occurred in 60.0 from the households inside the study (95 CI 47.41.four) (Table two). The SAR among all household contacts was 49.six (95 CI 37.81.5). Secondary transmission was substantially larger in households using the Alpha variant (83.three , 95 CI 55.95.two) compared with non-VOC viruses (55.0 (95 CI 39.80.1), p = 0.04). For household contacts, SAR was 77.eight (95 CI 49.42.6) in households together with the Alpha variant, compared with 42.five (95 CI 28.77.7) in households with nonVOC viruses, resulting within a significantly larger adjusted odds ratio (OR) for secondary transmission in households using the Alpha variant (p = 0.03).Table two.

A sizable proportion with the secondary circumstances (38.5 ) have been currently infected at Day 0, although 61.five of the secondary instances had been detected through study follow-up. The overall median serial interval (the amount of days amongst symptom onset from the major case and of a household make contact with) was estimated to 4 days (variety 11, n = 50). The median serial interval was similar for the Alpha variant (four days, variety 21, n = 17) and non-VOC viruses (4 days, variety 1 days, n = 31). The overall median interval between symptom onset in the main case along with the first rRT-PCR-positive test of a household make contact with was 3 days (range 12, n = 60), and this interval was equivalent for Alpha.
