MANILA, Philippines — Health authorities reported Tuesday they have detected 678 additional cases of three different coronavirus variants, including two considered as variants of concern.
Of these new cases, 289 are infected with the variant first detected in the United Kingdom known as B.1.1.7, while 380 are infected with the variant first identified in South Africa known as B.1.351.
The agencies also logged another nine cases of P.3, the variant first found in the Philippines.
This was the result of the latest batch of 744 samples that underwent genome sequencing.
The B.1.1.7 and the B.1.351 variants are classified as "variants of concern" due to their risk to human health. Both contain 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.
The P.3 variant carries both mutations, but the Department of Health said it is still not identified as a variant of concern.
The DOH also said the variant that emerged in South Africa was the most common variant among the samples sequenced with assigned lineages. Among the 5,917 samples with assigned lineages, 1,075 or 18.2% tested positive for the B.1.351 variant.
Meanwhile, 16% had the B.1.1.7 variant, 2.7% had the P.3 variant, and 0.03% had the P.1 variant, or the one first identified in Brazil.
