B.1.1.28.2, the Covid variant which was first found in Brazil last year is feared to cause more severe symptoms than original forms of the coronavirus, B.1 variant, that spread in Wuhan, according to a new study.
B.1.1.28.2 variant, also knows as the P.2 variant, was isolated from nasal/throat swabs of the travelers.
The researchers then studied Syrian hamsters that were infected with the P.2 variant, and compared it the hamsters infected with the B.1 variant.
The study, which is yet to be peer reviewed, found that the P.2 variant "induced body weight loss, viral replication in the respiratory tract, lung lesions and caused severe lung pathology in infected Syrian hamster model in comparison, with B.1 variant infected hamsters."
'The sera from B.1.1.28.2 infected hamsters efficiently neutralized the D614G variant virus whereas 6-fold reduction in the neutralization was seen in case of D614G variant infected hamsters’ sera with the B.1.1.28.2 variant," the study noted.
This means higher levels of antibodies were needed to neutralise the B.1.1.28.2 variant as compared to the B.1 variant.
The variant, now called the Gamma variant, according to the announcement by the World Health Organization has spread to more than 10 other countries, including the UK.
