BEIJING (AP) -- Iranians hoarded medical supplies, Italians urged doctors out of retirement and South Koreans prepared to pump billions into relief efforts Tuesday as the virus epidemic firmed its hold around the globe.
Mushrooming outbreaks in the Mideast, Europe and South Korea contrasted with optimism in China, where thousands of recovered patients were going home. A growing outbreak in the United States led schools and subways to sanitize, quickened a search for a vaccine, and spread fears of vulnerability for nursing home residents.
"We have moved to a new stage in the fight,'' said Dow Constantine, the political leader in King County, Washington, which is home to Seattle. All six US fatalities from COVID-19 have been in Washington state and Constantine said his county is buying a hotel to become a hospital for isolated patients.
World Health Organization leader Tedros Adhanom Ghebreyesus said outbreaks in South Korea, Italy, Iran and Japan were the agency's greatest concern. He said the virus was uniquely capable of community transmission but could be contained with the right measures.
''We are in unchartered territory,'' Tedros said.
South Korea saw its largest daily increase in new cases Tuesday, with 851 new infections reported, largely in and around the southeastern city of Daegu. In all, 5,186 in South Korea have tested positive for the virus.
In the capital of Seoul, drive-through virus testing centers began operating, with workers dressed head-to-toe in white protective suits leaning into cars with mouth swabs, a move meant to limit contact with possible carriers of the illness. Troops were also dispatched across the city to spray streets and alleys with disinfectants.
The country's death toll rose to 28 and President Moon Jae-in, calling the outbreak ''a grave situation,'' said his government would push to inject more than 30 trillion won ($25 billion) to fund clinics, aid for small businesses and other measures related to the virus. It requires parliamentary approval.
''The entire country has entered a war against an infectious disease,'' he said.
Shares on most Asian indexes rose for a second day, following the Dow Jones Industrial Average surging nearly 1,300 points, or 5%. Finance ministers and central bank leaders from the Group of Seven major industrial countries were to convene by phone Tuesday to discuss their response to the virus outbreak.
''The fear factor is still very high,'' said Kirk Hartman, president of Wells Fargo Asset Management.
In China, the count of new virus cases dropped again Tuesday, with just 125 new cases after a six-week low of 202 a day earlier. It's still by far the hardest-hit country, with 80,151 cases and 2,943 deaths.
China's ambassador to the United Nations said the country was winning its battle against COVID-19.
''We are not far from the coming of the victory,'' said Zhang Jun.
In Iran, after downplaying the coronavirus as recently as last week, authorities said they have plans to potentially mobilize 300,000 soldiers and volunteers to confront the disease. Concern over the outbreak now stretches to Iran's top leadership _ some of whom have fallen ill from the virus. Supreme leader Ayatollah Ali Khamenei even wore disposable plastic gloves while planting a tree to mark Iran's upcoming arbor day.
''Whatever helps public health and prevents the spread of the disease is good and what helps to spread it is sin,'' Khamenei said Tuesday.
Iran's judiciary chief, Ebrahim Raisi, said some people were stockpiling medical supplies for profit, and urged prosecutors to show no mercy.
''Hoarding sanitizing items is playing with people's lives and it is not ignorable,'' Raisi said.
In Italy, the count of infected people continued rising to 2,036 and officials said it could take up to two weeks to know whether measures including quarantines in 11 northern towns were working.
The US count of COVID-19 cases surpassed 100 in at least 11 states. On Capitol Hill, aides said negotiations were nearing completion on an emergency funding bill to fund a vaccine development and offer disaster loans to businesses hurt by the crisis.
Surgeon General Jerome Adams, a leading public health official in the US, urged calm.
''Caution, preparedness, but not panic,'' he said.
In Japan, questions continued to build about how the virus might affect the Olympics.
Chinese athletes have already fanned out of their country, with the table tennis team in Qatar, the women's basketball team in Croatia and wrestlers in Serbia.
The games are set to open in Tokyo on July 24 and the president of the International Olympic Committee said the organization remained committed to going forward as planned. An Irish bookmaker has been taking bets: 4/6 the opening ceremony will not go ahead in Tokyo or 11/10 that it will.
The games' CEO, Toshiro Muto, was planning a Wednesday teleconference with IOC's executive board.
More than 90,000 people have been sickened and 3,100 have died from the virus. A constantly expanding list of at least 70 countries have been affected, with Ukraine the latest to report a first case. (AP)
