The Department of Health (DOH) on Thursday, Oct. 21 said the biosurveillance activities of the country has been closely monitoring 46 sublineages of the Delta variant, and so far has not detected the AY.4.2 sublineage.


The Health department issued the statement following the reports on the increase of sublinage AY.4.2 in the United Kingdom (UK) and its detection in other countries outside the UK.

“As of this moment, experts are still studying the potential impact of the Delta sublineage on the transmissibility and severity of COVID-19. The particular Delta sublineage has not yet been detected among the COVID-19 positive samples sequenced in the country,” said Health Undersecretary Maria Rosario Singh-Vergeire in a statement.

“While this is being investigated, we emphasize that regardless of the variant, all COVID-19 cases should be managed similarly and as per current protocols. Each case must be immediately isolated and contact traced upon detection,” she added.

“Current evidence also showed that the presence or absence of a variant of interest or concern among cases do not dictate the appropriate clinical management. We should always remain vigilant against COVID-19, moreso that we are safely reopening our economy,” said Vergeire.

The DOH said mutations occur as part of the natural process of virus evolution.

The Health department then reminded the public that, while variants may contribute to increase or aggravate COVID-19 cases, “strict and proper adherence to the minimum public health standards reduces the risk of getting exposed to COVID-19.”

It also urged the general adult population to immediately get vaccinated to get additional protection against COVID-19.

Vergeire stressed that proper adherence to the minimum public health standards is still “our best protection and is the best way to curb the transmission, prevent the spread of the variants and slow down the appearance of mutations.”

Proper wearing of face mask and face shield, frequent hand washing or sanitizing, avoiding crowded places and observing physical distancing, and ensuring there is proper ventilation in our homes, workplaces, and public transportation, she said, are non-pharmaceutical interventions that all of us can do to ensure that we and everyone around us are safe.

“Getting fully-vaccinated is also another layer of protection that can help us from getting severe COVID-19,” said Vergeire.
