Investigators have demonstrated that speaking and coughing produce a mixture of both droplets and aerosols in a range of sizes, that these secretions can travel together for up to 27 feet, that it is feasible for SARS-CoV-2 to remain suspended in the air and viable for hours, that SARS-CoV-2 RNA can be recovered from air samples in hospitals, and that poor ventilation prolongs the amount of time that aerosols remain airborne.
We detected in total 65776 variants with 5775 distinct variants.

In other words, a dose of virus particles capable of causing an infection would linger in the air much longer after speech than a cough. (In this modeled scenario, the same number of droplets were admitted during a 0.5-second cough as during the course of 30 seconds of speech.)
It's racist and it creates xenophobia," University of California at Berkeley Asian American studies lecturer Harvey Dong told The Washington Post. "It's a very dangerous situation."

Ryan is not the first WHO official to push back against the phrase. Director-General Tedros Adhanom Ghebreyesus said earlier this month that the term is "painful to see" and "more dangerous than the virus itself."
ICTV announced "severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)" as the name of the new virus on 11 February 2020. This name was chosen because the virus is genetically related to the coronavirus responsible for the SARS outbreak of 2003. While related, the two viruses are different.
From a risk communications perspective, using the name SARS can have unintended consequences in terms of creating unnecessary fear for some populations. ... For that reason and others, WHO has begun referring to the virus as "the virus responsible for COVID-19" or "the COVID-19 virus" when communicating with the public. Neither of these designations is [sic] intended as replacements for the official name of the virus as agreed by the ICTV.
