The Regional Epidemiology and Surveillance Unit (RESU) of the Department of Health (DOH) in Western Visayas has advised the local government unit (LGU) of Valladolid in Negros Occidental to do a backtrack and determine where the 35-year-old pregnant woman got the Lambda variant of COVID-19.
According to Dr. Jessie Glenn Alonsabe, RESU head, they believe the patient may have gotten the virus from someone else since her immediate family and all other close contacts have tested negative for the virus.
“During the backtracking dapat hibaluon kon sin-o ang naglaton sa iya,” Alonsabe explained.
Meanwhile, Valladolid Mayor Enrique Miravalles revealed that the 35-year-old woman and her newborn son have tested negative following a re-swab.
Miravalles is in disbelief as the woman has no travel history outside of the province.
Even though the woman and her household have already tested negative, he has ordered to closely monitor the patient and her family.
Earlier on Monday, the DOH-6 confirmed that the country’s first case of the Lambda variant is from the town of Valladolid.
The Lambda variant, also known as the C.37 lineage, was first detected in Peru in August of 2020.
Meanwhile, DOH Technical Advisory Group’s Dr. Edsel Salvana said there is yet no conclusive study whether COVID-19 vaccines can give immunity against the Lambda variant or not.
“Mukha po siyang may mga mutations na maaring makaapekto sa efficacy ng ating vaccines pero hindi pa po ito proven,” Salvana said at Malacañang’s virtual presser.
Dr. Nina Gloriani, chairperson of the vaccine expert panel, said more studies are needed to determine the effect of Lambda on COVID-19 vaccines./DGB, WDJ
