I have been sick almost a week no strep, no flu throat hurts, sore, hoarse now lost my voice and seems get worse at night with a dry cough.?

Voice. Probably viral URI with laryngitis. Voice rest, lots of clear fluids, tylenol, throat lozenges. Should get better in next 7-10 days.
Viral infection. Its probably viral infection. TRy paracetamol, hot fluids, lozenges and rest should help.
