Brazil confirms 3rd omicron case, considers new measures

Brazilian health officials have confirmed a third known case of the omicron coronavirus variant

Much remains unknown about the new variant, including whether it is more contagious, as some health authorities suspect, whether it makes people more seriously ill and whether it can thwart the vaccine.

The number of daily deaths and new infections from the virus are currently low and vaccination coverage is higher than in many countries — including the United States. But Brazil has suffered heavily from the coronavirus pandemic, with more than 610,000 deaths, second only to the U.S.

Brazilian mayors and governors, in charge of implementing local measures to rein in COVID-19, were closely watching the situation unfold, waiting for more information on the new variant.

In Rio de Janeiro, where New Yea’s Eve and Carnival usually attract millions of visitors each, Mayor Eduardo Paes said both events were still scheduled, but warned they would only go forward if it is safe to organize them.

“I want to remind you that planning an event does not mean that it will necessarily take place. After all, it is entirely possible to cancel what was planned,” Paes said Tuesday in a recorded statement.

Sao Paulo Gov. João Doria also said Tuesday the state’s COVID-19 scientific committee will reassess the scheduled Dec. 11 end of mask mandates.

The federal government said Tuesday it needed “further clarification” on the epidemiological situation in Angola, Malawi, Mozambique and Zambia before deciding whether to suspend flights from these countries, as recommended by the Brazilian Health Regulatory Agency, known as Anvisa.

The South American country has already blocked flights originating from or with stopovers in South Africa, Botswana, Eswatini, Lesotho, Namibia and Zimbabwe.

Rodrigo Cruz, the Health Ministry's number two, said on Wednesday the nation was also debating whether to require vaccine certificates from arriving passengers. Brazil does not currently require COVID-19 vaccination from foreign travelers entering the country.

In a technical note sent to the government on Nov. 12, Anvisa asked the government to consider such a step, citing a 4.6% increase in tourism activities in October and upcoming end-of-year celebrations.

The lack of vaccine requirement "may allow Brazil to become one of the countries of choice for unvaccinated tourists and travelers, which is undesirable from the point of view of the risk that this group represents for the Brazilian population,” Anvisa said.

Other suspicious cases are being investigated, including in Rio de Janeiro and Minas Gerais states, with a final number expected to be released later Wednesday, Health Ministry said.
