Manaus
Recent events

Manaus was one of the host cities of the 2014 FIFA World Cup and one of the seats of some Olympic football games. It was the only host city in the Amazon rainforest and the most geographically isolated, being further north and west than any of the other host cities. A massive prison riot occurred in January 2017, having begun in Manaus and later spreading to two additional cities in Brazil, thus unleashing security problems within the country.

During the COVID-19 pandemic in Brazil, an estimated 76% of the population of Manaus was infected with coronavirus, and the possibility of herd immunity was discussed. However, a second outbreak infected people in Manaus, this time with the Lineage B.1.1.248 variant starting in early January 2021.
