Went on a Royal Caribbean Cruise?

Had fun and snorkeled but got very sick on arrival home. Tested negative for covid. Was the sickness worth the fun. Hell no, I had fever and lung congestion healing but slow. Wife ok for now.

Other family took different cruise line at same to west caribbean and mother daughter got similarly ill with fever and cold symptoms.

I haven’t had a cold in over 2 years. Do I think the cruise gave me the sickness? For sure..
