One way to help distinguish which viha is being spoken of, is to add the prefix sauna/viha(ta)…
Leil is the steam that rises from the sauna/ahju keris (stove's rocks) when you throw water on them. Put that idea on hold for now, just in case, unless you are fortunate enough to have your own private, family “karantiini/saun“, so to speak. But remember, this sacrifice and all the other eba/mugavused (inconveniences) are “me ühise tervise nimel“, in the name of our collective health! Olge terved – “Be healthy”, stay healthy!
P.S. Wikipedia also has the entry of “bath broom” for viht and there is a saunalise (sauna user's) manual of sorts which is also entitled “Vihaga, kuid vihata. Eesti rahva esimene sauna-aabits” (With a viht, but without viha (anger). Estonians' first sauna primer) by Rein Sikk, 2015, Tammerraamat, hardcover, 176 pgs. The surname Sikk, by the way, is not like sick (with the virus), but is the name for a male goat or deer (both sikk and sokk) and also the name of an insect, the longhorn beetle, or one of the family thereof, the siklased, of which many are serious pests. Not the given author / journalist from Kadrina of course; vastupidi, au contraire!
