Billionaires are spending millions to fight the novel coronavirus.

However the gifts, which total $130.75 million thus far according to Business Insider’s calculations, may not be doing much to help those already suffering from the growing global health crisis. Of the portion of the donations that are designated to help those on the front lines of the coronavirus outbreak, some are going to organizations designated by the Chinese government to handle the crisis, Fortune’s Eamon Barrett reported. However, medical workers throughout Wuhan are complaining on social media of not receiving any aid from these groups, according to Fortune.

China’s richest man announced the donation on Chinese Twitter-like platform Weibo, Business Insider reported. Two Chinese government research organizations will receive $5.8 million of the gift to work on creating a vaccine, according to Axios.

"We know that the battle between humanity and disease is a long journey," Ma's foundation said a post on its Weibo account. "This money will help various medical research efforts and help disease prevention."

The Gates' pledge will be used to support treatment efforts across the globe, build infrastructure to treat patients in Africa and Southern Asia, and fund the development of a vaccine, the couple's foundation said in a press release. They previously pledged to donate $10 million.

Bill Gates has long warned that the world is ill-equipped to manage a pandemic, Business Insider's Aria Bendix reported. The WHO has yet to conclusively say that the novel coronavirus has reached the level of a pandemic, but Gates disagrees. "I hope it's not that bad, but we should assume it will be until we know otherwise," Gates wrote in an op-ed for the New England Journal of Medicine February 28.

Gates outlined his suggestions for containing the crisis in the essay, including sending highly trained healthcare workers to low- and middle-income countries in Africa and Southern Asia, establishing an international database on information on the outbreak, and funding vaccine manufacturing facilities.

The €1 million gift, which will be paid out through Soros' Open Society Foundation, will go to helping Budapest's municipal government provide for the Hungarian capital's elderly and homeless populations during what Soros called an "unprecedented emergency," according to a statement emailed to Business Insider.

"I was born in Budapest, in the middle of the Great Depression, barely a decade after the Spanish Flu left thousands of dead in Budapest," Soros said in a statement. "I lived through World War II, the Arrow Cross rule, and the siege in the city. I remember what it is like to live in extreme circumstances."

After leaving Budapest as a teenager, Soros built an $8.3 billion fortune running what was once the world's largest hedge fund, Business Insider reported.
