CDC now calls coronavirus Delta variant a 'variant of concern'

Meanwhile, as Public Health England announced last Monday, COVID-19 vaccines from Pfizer and AstraZeneca are effective against the Delta variant and have prevented the hospitalisation of several people who were infected with the new strain.

The Delta variant has been rapidly expanding throughout Canada.

Other variants, circulating in the U.S., classified by CDC as variants of concern include the B117 (Alpha), B1351 (Beta), P1 (Gamma), B1427 (Epsilon), B1429 (Epsilon), and B16172 (Delta). Astrazeneca's Covishield vaccine manufactured by Serum Institute of India has inoculated the majority (88 per cent) of the population in India so far.

The paper, that is not yet peer-reviewed concluded that both the vaccines offered a high level of protection against the Delta variant of coronavirus.

After 28 days post-vaccination, he said there was "only really" a difference in protection "of about 18 per cent" for the AstraZeneca vaccine, "which is not great".

The US Centers for Disease Control and Prevention has classified the Delta, a highly transmissible COVID-19 variant first identified in India, as a "variant of concern".

Australia's Victoria state records slight rise in COVID-19 cases
The single new locally acquired case of COVID-19 in Victoria was found in a man who got tested as soon as he felt symptomatic. Dr Young said three close contacts had already tested negative, including relatives they were staying with in Caloundra.

The study findings also reassert that vaccination with Covishield has a significant impact in reducing hospitalisation in the country.

Milwaukee's Commissioner of Health, Kirsten Johnson, reported two cases of the Delta variant were detected in Milwaukee County at the end of May.

Another analysis of Delta variant was done in Scotland and published covered a period between April 6 and June 6.

While it's important to be cautious and self-monitor for symptoms of COVID-19, experts aren't entirely sold on the data out of the United Kingdom study, and have yet to see signs of these different symptoms reported in Canada. "We will study and learn more about this variant".

The data also suggests that the risk of hospitalization among those infected with the Delta variant was double that of the Alpha variant, especially in respondents with five or more severe medical comorbidities.
