Washington, D.C. March 26, 2021 (PAHO)—The Pan American Health Group (PAHO) said 32 countries and territories in the Americas have reported the presence of as a minimum one of the three “variants of concern” of the virus that causes COVID-19, SARS-CoV-2, according to a brand new Epidemiological Update.
These variants also can simply increase transmissibility of the virus, increase its virulence, or decrease the effectiveness of public effectively being and social measures or diagnostics, vaccines, and therapeutics, though much remains to be realized about them.
Fresh measures to prick transmission – including frequent hand washing, wearing a hide, bodily distancing, correct ventilation and avoiding crowded locations or closed settings – continue to work against new variants by reducing the quantity of viral transmission and therefore also reducing opportunities for the virus to mutate.
The countries and territories that reported one or extra of these variants include Argentina, Aruba, Barbados, Belize, Brazil, Bonaire, Canada, Cayman Islands, Chile, Colombia, Costa Rica, Cuba, Curacao, Dominican Republic, Ecuador, French Guiana, Guadeloupe, Jamaica, Martinique, Mexico, Panama, Peru, Puerto Rico, Saint Barthelemy, Saint Martin, Saint Lucia, Sint Maarten, Trinidad and Tobago, Turks and Caicos, United States of The United States, Uruguay, and Venezuela.
Since the initial identification of SARS-CoV-2, greater than 845,000 full genomic sequences have been shared globally by means of publicly accessible databases. “The ability to track the information in advance valid time has an on the spot impact on the public effectively being response to the COVID-19 pandemic, allowing to establish adjustments in epidemiological patterns, in virulence, or in the decrease in therapeutic efficacy, among other adjustments,” the PAHO replace smartly-known.
To this point, three variants of SARS-CoV-2, first identified in the United Kingdom, South Africa, and Brazil and identified as B.1.1.7, B.1.351, and B.18.104.22.168, have been labeled by the World Health Group (WHO) as variants of concern (VOC), in session with the WHO Working Neighborhood on the Evolution of SARS-CoV-2. Variants in another category, variants of interest, covering three extra styles, have been reported in Brazil, the United States, and six other countries and territories.
PAHO’s replace said, “Given the most well-known useful resource requirements mandatory to sequence all samples in the effect apart to establish variants, PAHO continues to work closely with laboratories in the countries of the Americas to abet establish samples which need to be prioritized for genomic sequencing.”
To this point, 21 countries are participating in the COVID-19 Genomic Surveillance Community, with reference sequencing laboratories in Brazil and Chile. PAHO is working together with the countries of the effect apart to expand and strengthen the regional community, as this mechanism shall be serious to tracking the unfold or appearance of new variants of concern. PAHO shall be supporting epidemiological experiences in Brazil to understand the patterns of transmission, reinfection, and the severity of cases from the diversified circulating variants.
