After some analysis from Helix Lab, The New York Times also pointed out that some US states where there is an upward Covid-19 cases trend are undoubtedly the most affected by several coronavirus variants.
According to The New York Times, the application of Covid-19 vaccines accelerated since last December, so new cases decreased nearly 80% from mid-January to March.
However, these states also lifted measures during this stage to curb the spread of SARS-CoV-2, and now mobility data showed an increased number.
According to the US newspaper, infections are increasing in states with a strong presence of variants such as Michigan, where the steepest rise in recent weeks has been reported.
The most transmissible and deadly variant of the coronavirus, B.1.1.7, first found in the UK, currently accounts for 70% of all new infections in that European country, Helix Lab reported.
Although vaccines licensed in the United States are effective against B.1.1.7 and will significantly delay the spread of the virus, some experts said that 70 to 90% of the US population would need to be vaccinated before transmission slows down substantially.
While more than three million doses are currently applied every day in the United States, less than 20% of the country’s inhabitants were fully vaccinated.
