MANILA, July 19 (Philippines Daily Inquirer/ANN): Health experts have warned that a community transmission of the more contagious Delta variant of Covid-19 was already taking place and the Philippines must brace for another surge in infections following the detection of the virus in 11 persons who did not travel abroad.
The Department of Health (DOH) last week confirmed the local infections of the Delta strain, but remained silent on local transmission as it continued to investigate the link among these cases.
“But, if I may speculate, it’s difficult to not consider a possible community transmission already happening,” said infectious disease expert Dr. Rontgene Solante. A local or community transmission happens when a person infects another individual even when both of them had not left the country.
But government adviser Dr. Edsel Salvana said he would rather wait for the genome data in order to map out the variant transmission.
“If the different places show very closely related viruses, then that may be the case. But if they show different genome sequences, then these are separate introductions,” he said in a text message.
The Delta variant was first reported in India and continues to wreak havoc in many countries across the globe.
In a Viber message on Sunday, Solante, who also sits in the government’s Vaccine Expert Panel, shared questions that ought to be answered: “Where did these local cases come from? Are they index cases or secondary cases?” An index case refers to the first patient in a certain population.
He said that the Delta cases being “clustered” in different regions was already “a sign that a possible local transmission is already happening.”
In a separate online interview, former government health adviser Dr. Tony Leachon said the current high positivity rates in different and distant provinces and cities such as Davao, Iloilo, Bacolod, Mariveles, General Santos City, Cagayan de Oro, Baguio and Laoag signified active transmission.
“Our local transmission of Delta variants is underreported due to lack of genome surveillance studies particularly in hot spots outside of the NCR (National Capital Region),” Leachon said.
Leachon earlier pushed for the inclusion of Indonesia in the Philippines’ travel ban and said he would do the same with Malaysia and Thailand due to their present Delta variant surges.
Philippine National Police chief Gen. Guillermo Eleazar on Sunday ordered the fielding of more cops to stop superspreader events that could worsen the local spread of the Delta strain.
He warned organizers of such events that they would be facing charges.
Eleazar directed police commanders to coordinate closely with local government units (LGUs), particularly barangays, to ensure minimum health standards were being observed and no mass gatherings were held in their areas.
The Philippine General Hospital (PGH) and several other medical facilities were likewise on heightened alert to ward off a potential surge of the Delta variant.
2-level surge response
On Sunday, the DOH has also laid out a two-level surge response—at the community or in a facility—that included stocking up on medicines and closing the supply gap in oxygen, according to a communication sent to hospitals on July 16.
The DOH said the government must ensure an adequate supply of oxygen for COVID patients as the country’s current daily consumption of 74,400 cylinder tanks was estimated to double in case of a surge.
The DOH also recommended face masks even at home when living with an elderly or a person with an underlying health condition. - Philippines Daily Inquirer/ANN
