Yep, Serbo-Croatian (technically Bosnian-Montenegrian-Croatian-Serbian) "K" for "koronavirus". The only difference between languages is Latin versus Cyrillic.
Croatia, for example has its official coronavirus webpage as https://koronavirus.hr

"a language is a dialect with an army and a navy"
There are definitely more differences between the lexicon and grammar of those languages apart from the alphabet they are written with.
Not very big differences, mind you. But ignoring them altogether or making them bigger than what they are enters the realm of politics.
Anyway, the english wikipedia article does a decent job capturing a few key differences in the dialect continuum https://en.wikipedia.org/wiki/Comparison_of_standard_Bosnian...
I am well aware of them: Croatian is not my native language. But, I learned it and I am conversational in the Shtokavian (Štokavian) dialect. I am Štokavski. This is the standard dialect of Croatian, in Croatia.
My family however were Čakavski. They spoke the Chakavian (Čakavian) dialect. They are from the islands of Croatia. Unfortunately, it is a dying dialect of Croatian that is Venetian in origin. It is not mutually intelligible with Štokavian, but everyone in Croatia seems fond of it.
