USA Today reports Trump has Officially Begun to Withdraw the US From the World Health Organization as Pandemic Spikes:
The Trump administration has officially begun to withdraw the United States from the World Health Organization, even as the COVID-19 pandemic continues to grip the globe and infections spike in many states across the U.S.
Congress received formal notification of the decision on Tuesday, more than a month after President Donald Trump announced his intention to end the U.S. relationship with the WHO and blasted the multilateral institution as a tool of China. The White House said the withdrawal would take effect on July 6, 2021.
[...] The formal withdrawal comes as the United States nears 3 million reported coronavirus cases and more than 130,000 deaths, according to Johns Hopkins University data. Globally, there have been 11.6 million cases and almost 540,000 deaths.

The SARS-CoV-2 (2019-nCoV) virus is about 0.1 microns in diameter [thelancet.com]:
I am not aware of any viral particles as huge as 10 microns across; such a particle would be easily visible under an ordinary optical microscope and would almost certainly be visible to the naked eye on a surface with sufficient contrast. The Variola virus that caused smallpox is one of the largest known viruses at about 300nm across (0.3 microns).
