Mexican health authorities will begin this week to use a broader definition to identify possible coronavirus cases, a top official said on Monday, after questions about whether testing was too limited.

Mexico registered 3,541 new cases and 320 more fatalities on Monday

Overall, Mexico has recorded 563,705 cases and 60,800 deaths

Adds new definition for suspected cases, context

MEXICO CITY, Aug 24 (Reuters) - Mexican health authorities will begin this week to use a broader definition to identify possible coronavirus cases, a top official said on Monday, after questions about whether testing was too limited.

A new definition of "suspected" infections will come into use on Tuesday and will include loss of smell, loss of taste and diarrhea as possible COVID-19 symptoms, Deputy Health Minister Hugo Lopez-Gatell said.

It will also allow a person with just one symptom, rather than two or more, to be viewed as potentially infected.

"This gives you a larger margin of potential, which will result in faster, timelier attention for a greater number of people," Lopez-Gatell told a news conference.

The broader definition could lead to a higher number of cases but that would be an "artificial effect" before stabilizing, he said.

Mexico's policy is to apply tests to people who show sufficient symptoms, he noted.

Mexico on Monday reported 3,541 new confirmed cases of the novel coronavirus and 320 more fatalities, bringing its total tallies to 563,705 cases and 60,800 deaths.

It has the world's third-highest toll from the pandemic and the government has said the real number of infected people is likely significantly higher than confirmed cases.

Last Friday, the World Health Organization's top emergency expert, Mike Ryan, noted that Mexico applies about three tests per 100,000 people, compared with about 150 tests per 100,000 people in the United States, and has a high positivity rate.

"That means many, many, many people are either being under-diagnosed or diagnosed late, and certainly this is having a differential impact in the country," Ryan told a news conference in Geneva.
