WASHINGTON (AP) — President Joe Biden's administration will help 50 countries identify and respond to infectious diseases, with the goal of preventing pandemics like the COVID-19 outbreak that suddenly halted normal life around the globe in 2020.

U.S. government officials will work with the countries to develop better testing, surveillance, communication and preparedness for such outbreaks in those countries, according to a senior Biden administration official who briefed reporters Monday about the program on the condition of anonymity. The official did not share a list of countries that will participate in the program.

The announcement comes as countries have struggled to meet a worldwide accord on responses to future pandemics. Four years after the coronavirus pandemic, the prospects of a pandemic treaty signed by all 194 of the World Health Organization's members are flailing.

The U.S. program will rely on several government agencies — including the U.S. State Department, the Centers for Disease Control and Prevention, Health and Human Services and the U.S. Agency for International Development, or USAID — to help countries refine their infectious disease response.

Congo is one country where work has already begun, the official told reporters. The U.S. government is helping Congo with its response to an mpox virus outbreak, including with immunizations. Mpox, a virus that's in the same family as the one that causes smallpox, creates painful skin lesions. Last year, the World Health Organization declared mpox a global emergency, with more than 91,000 cases spanning across 100 countries to date.

The White House on Tuesday is releasing a website with the names of the countries that are participating in the program. Biden officials are seeking to get 100 countries signed onto the program by the end of the year.

The U.S. has devoting billions of dollars to the effort. Biden, a Democrat, is asking for $1.2 billion for global health safety efforts in his yearly budget proposal to Congress.
