"The pandemic is accelerating," Tedros said. "We need to attack the virus with aggressive and targeted tactics."

He noted that it took 67 days to confirm the first 100,000 cases, 11 days for the second 100,000 and four days for the 100,000 cases. He urged the world's wealthiest countries to work together to combat the outbreak.

“We need unity in the G-20 countries,” he said. “Political commitment at the G-20 level means a very strong solidarity that can help us to move forward and fight this pandemic in the strongest terms possible.”
