Hi
A warm welcome to HCM.
No you don't have Paratyphoid fever any more.
You do not need to restart antibiotics as you have completed a 10 days course and deffervescence has already occured. Widal test is not a very specific test as it does not detect the antigen. It measures the antibody level, in other words the response of body immune system to the agent, Salmonella.

Don't worry.
All the best.
