The recommendation of the IATF for a 10-day facility-based quarantine for returning overseas Filipino workers and their Covid-19 testing on the seventh day of quarantine is based on solid science, an infectious disease expert said.
Dr. Edsel Salvana said the US Center for Disease Control and Prevention has done the modelling which showed residual risk of infection after 10 days of quarantine is acceptable but is not acceptable on testing upon arrival.
Salvana, director of the Institute of Molecular Biology and Biotechnology at the University of the Philippines Manila National Institutes of Health, said more cases are diagnosed on the seventh day of quarantine.
He said, “We are seeing a major increase in the Delta variant globally, which is about 60 percent more contagious than Alpha. The UK is having an unprecedented spike in cases, mostly from the Delta variant in the unvaccinated people and they have had to delay their opening.”
