Is Influenza Contagious?
an infection is likely
Detailed Answer:
Hello,
it sounds like an infection. You haven't mentioned any specific symptoms (like cough, sore throat, runny nose) so there is some uncertainty about the diagnosis. The fact that your husband was sick and you got sick after he did can be probably attributed to common viral diseases like influenza or others.
When a patient has high fever and unless the diagnosis is certain, a visit to the doctor is recommended. In most cases the cause is not serious but there are exceptions to this rule... Pneumonia and other serious diseases may present with the same symptoms as common infections, so clinical examination is very important.
Regarding your low temperature it could be due to sweat (when the axillae are humid, the thermometer cannot provide accurate readings) or due to the falling temperature. When an infected patient either starts to get better or has a falling fever (after taking ibuprofen for example) then low temperatures are normal and may persist for a few days.
I don't see any clues about thyroid disease here. The low temperature is not very concerning at this time.
So in conclusion, I believe that a visit to your doctor would be appropriate if you still have fever. If you're already better and afebrile for at least 24 hours without ibuprofen, then you can wait to see what happens. Any sign of recurring fever or worsening should drive you to the doctor...
