Any get sick while on a fast? (dry throat,coughing, losing voice cold-type of sick)

I am on day 6 and I woke up this morniing with very dry throat, a very dry cough, yet I can feel phlegm stuck in my throat.

I have almost lost my voice as well.

It is was possible I picked up something the first day of my fast and it has taken time to germinate, and show its self? I have never felt sick while on a fast, at least not like "I have a cold or the flu "sick.

I was wondering if anyone could tell me if this is normal so I know if everything is okay. Maybe Chris B has a some good information for me regarding this issue
