GENEVA, May 26 (CGTN) - International health authorities expressed concern Tuesday over signs the spread of the new coronavirus is "still accelerating" in Brazil, Peru and Chile.

"In South America, we are particularly concerned that the number of new cases reported last week in Brazil was the highest for a seven-day period, since the outbreak began," said Carissa Etienne, director of the Washington-based Pan American Health Organization.

"Both Peru and Chile are also reporting a high incidence, a sign that transmission is still accelerating in these countries," she said at a weekly briefing.

The Pan American Health Organization, which serves as the regional office for the World Health Organization, has been monitoring the pandemic in Latin America and the Caribbean.
