Chile’s Parliament on Wednesday passed a new law requiring everyone to wear face coverings at work.
The bill, passed by the Chamber of Deputies, came as the country struggles with the Zika virus, with authorities saying more than 1,000 people have died since it was introduced last year.
The new law applies to public and private sector workers.
It also allows businesses to impose fines on people who fail to wear the face cover.
In the past, Chile has required employees to wear full face cover and had a mandatory ban on wearing masks in public.
However, the government recently eased the rules, allowing some employees to use masks, and a number of businesses have opened shop in the capital Santiago.
Chile’s President Michelle Bachelet said the new law is a step in the right direction.
“The new legislation makes a commitment to work for everyone,” she said.
“We have to protect everyone’s health, and I think this is a very good step forward,” she added.
The country’s Zika outbreak has been blamed on a lack of mosquito nets.
Authorities have not said how the masks will be distributed.
The government has not released the price for the masks, but the government estimates it will cost around 2.5 million reais ($5.4 million).
