Philippines detects 10 more cases of coronavirus variant first detected in India
MANILA, Philippines — Philippine health authorities announced Saturday that they detected 10 more cases of the more infectious coronavirus variant which was first identified in India, bringing the total number of cases of this variant to 12.
All but one of the 10 new patients infected with the B.1.617.2 variant are from the MV Athens Bridge from India, where 12 Filipino seafarers contracted COVID-19.
Four of them are still admitted in a Manila hospital, while five are in an isolation facility, the DOH said.
The DOH said samples from only nine of the 12 seafarers were sequenced, as samples from the remaining three were “not eligible” for the process.
A seafarer who disembarked in Belgium and flew back to Manila via the United Arab Emirates also contracted the B.1.617.2 variant. He arrived in the Philippines last April 24 and completed his isolation last May 13.
Health authorities said they also detected 13 new cases of the coronavirus variant first identified in the United Kingdom (B.1.1.7), seven of the variant first identified in South Africa (B.1.351) and one of the variant first identified in the Philippines (P.3).
Of the additional B.1.1.7 cases, 10 are local cases and three are from returning overseas Filipinos. All of them have recovered except for one who has died.
Among the new B.1.351 cases, two are local cases, two are returning overseas Filipinos and three are still being verified whether they are local cases or not. Of them, one has died, two are still active and four have recovered.
The additional P.3 case is from Region IX and has succumbed from COVID-19.
The variants first identified in India, UK and South Africa have been declared as variants of concern. A variant of concern is defined as one with increase in transmissibility, increase in virulence or change in clinical disease presentation, and decrease in effectiveness of public health measures or available diagnostics, vaccines and therapeutics.
The B.1.617 variant, first found in October 2020, carries several mutations, including the L452R and E484K.
The L452R mutation is associated with increased transmissibility and reduced antibody neutralization, which may help the virus get past antibodies. Meanwhile, the E484Q mutation, which is similar to E484K mutation, may also help the virus escape immune response.
Both the B.1.1.7 and B.1.351 variants carry the N501Y mutation, which is associated with increased transmissibility, while B.1.351 carries the E484K mutation, which may help the virus dodge some antibodies. — Xave Gregorio with reports from Gaea Katreena Cabico
