The Pasay City Epidemiology and Disease Surveillance Unit (CESU) has observed that most of the transmissions in the city are occurring in households or families.
"Around 64 to 66 percent of our cases are people living in one household or compound," CESU head Mico Llorca said during an interview with ANC on Thursday.
"This is very unusual actually because we've never seen this last year or even in January," he said.
Llorca was referring to compounds where houses are situated close to each other.
Two factors now are being looked at by CESU regarding the recent surge in COVID-19 cases in Pasay City. First is the possibility of the more contagious United Kingdom COVID-19 strain, and the second, residents who did not inform their respective barangays after getting tested outside the city.
Llorca disclosed that the results of the genome sequencing for the first 17 samples will come out next week.
Currently, 97 households in 56 barangays in Pasay City have been placed under localized community quarantine.
The barangays are: 28, 29, 32, 37, 40, 57,58, 66, 68, 71, 76, 81, 95, 98, 100, 107, 109, 118, 122, 132, 135, 136, 143, 155, 156, 159, 162, 175, 177, 178, 183, 190, 192, 201, 171, 7, 8, 14, 20, 26, 36, 51, 59, 65, 74, 90, 96, 99, 110, 111, 116, 131, 161, 188, 193, and 194.
Llorca said they will not immediately lift the containment of these areas after 14 days. He said they would extend the quarantine should the need arise.
