A week before the outbreak started in Mexico and other Central American countries, the US Department of Health and Human Services (HHS) said the number of new cases was at its highest level in three years.
“We are still very concerned about this situation,” Dr Michael Osterholm, director of the National Center for Emerging and Zoonotic Infectious Diseases, said at a briefing.
“The US is still experiencing a significant increase in new cases.
We are concerned that we are still seeing the same pattern in many parts of the world.”
Osterholm said there were no immediate signs of an increase in the US, which has seen an increase of 1.3 million new cases since the beginning of the pandemia.
“There’s been a slight increase in infections, but not enough to pose a threat,” he said.
Mexico is the epicentre of the outbreak, with nearly 1.2 million cases.
The US has reported more than 1.5 million cases and 2.2million deaths.
In the first week of the crisis, Mexico saw a total of 1,977 deaths, while Honduras had a total death toll of 627.
Mexico’s death toll was 4,700 and Honduras was 472.
A number of countries in the region reported their highest death tolls.
Guatemala reported the highest number of deaths, at 9,935.
The number of people in hospitals was reported to be 2,564,000.
The death toll in Colombia was 5,300.
The outbreak has claimed the lives of at least 15,000 people and has killed more than 40,000 since the start of the year.
The WHO, the agency responsible for monitoring the disease, says the pandeman is spreading in Mexico by infecting infected travelers who are not vaccinated, and by making people more vulnerable to infection.
Honduras, Guatemala, El Salvador, Honduras and the US have reported the most cases.
There have been no new infections.
