(CNN) Remote indigenous communities in Brazil, who have little or no contact with the outside world, are facing a grave threat from Covid-19 -- and advocates accuse the government of failing to protect these vulnerable groups. The virus has already killed a member of the Marubo and a member of the Tikuna indigenous people living in the remote Javari Valley, and more than 450 people have been infected, according to the Brazilian government. "The situation in the Javari Valley is critical," said Douglas Rodrigues, a physician who has worked with recently contacted indigenous groups over the past 40 years. The largest concentration of isolated communities is based in the Javari Valley, a region the size of Austria, located in southwest Amazonas state, near the border with Peru. The nearest town, Atalaia do Norte, is nearly 700 miles from the Amazonas state capital of Manaus.
