Sudden onset of sore throat, wheezing, loss of voice, fluid in ears but no runny nose fever or any other symptoms could this be strep throat?

Unlikely: Most probably it's a viral infection leading to this constellation of symptoms, unlikely to be streptococcal pharyngitis from the outset, although bacteria may kick in later, but symptoms will change. Saline nasal washes, salt water gargles for decongestion remain the mainstay for treatment though, together with voice rest,fluids,bronchodilator for wheezing if you're prescribed one, c MD if worse
