Heard this a couple years ago. Laughed at it.
Now confirmed.
COVID-19 began in Wuhan, China in December 2019,
shortly after city-wide 5G had “gone live,” that is, become an
operational system, on October 31, 2019. COVID-19 outbreaks
soon followed in other areas where 5G had also been at least
partially implemented, including South Korea, Northern Italy,
New York City, Seattle, and Southern California. In May 2020,
Mordachev [4] reported a statistically significant correlation
between the intensity of radiofrequency radiation and the mortality
from SARS-CoV-2 in 31 countries throughout the world.”
