GENEVA, March 4 (CNN) - The WHO is warning of a global medical equipment shortage and estimates that about 89 million medical masks, 76 million examination gloves and 1.6 million goggles will be required globally for health care workers to respond to the outbreak.

At a news briefing Tuesday, WHO Director-General Tedros Adhanom Ghebreyesus said that each month, the organization estimates that about 89 million medical masks, 76 million examination gloves and 1.6 million goggles will be required globally for health care workers to respond to the outbreak.

The virus has infected more than 92,800 people and killed at least 3,200 since it was first identified in the Chinese city of Wuhan in December last year. It has now spread to more than 75 countries and territories, with self-sustaining clusters forming in South Korea, Japan, parts of Europe, Iran and the United States.
