Sick husband but don't think it's COVID

Last Thursday, my husband said he didn't feel well.  He had a low fever and cough.  He is eating well.  I have spent the last few days taking care of him.  I make meals, bring him tea with honey and water to try to curb his cough 😷.  On the positive side, he eats well and breathes fine.  I don't think he has COVID.  He might have influenza A or B.  I watch him because he is 75 years old.  I'm not physically exhausted but I am tired of nursing him and bored.  He grumbled at me a couple times yesterday because he is frustrated with the cough.  Tonight I felt pent up but cooking dinner and watering the plants eased the feeling.  I'm sure we will be in quarantine at least 'til April 30 and I am trying to adjust to the new situations as best I can.
