I was watching a video https://youtu.be/XUK7ORYBgIs?t=235 until a Japanese vlogger stumbled on reading the phrase:
SARS様ウィルス
The phrase itself seems pretty widespread and even Wikipedia mentions it https://ja.wikipedia.org/wiki/%E9%87%8D%E7%97%87%E6%80%A5%E6%80%A7%E5%91%BC%E5%90%B8%E5%99%A8%E7%97%87%E5%80%99%E7%BE%A4
If I encountered this, I would go with よう not さま.
What is the correct reading?
