Welcome to HealthcareMagic forum.
Typhoid and malaria
are infectious disease which is completely cured with proper antibiotic therapy. I presume you have been treated completely.
Post infection, it is necessary to take a proper diet, drink plenty of water, take vitamin supplements to get back into shape soon. Alcohol may have some effects on recovery, but not significant one. However in presence of previous liver
disease, this can be devastating.
The bottom line is, No, alcohol currently will not have any effects on typhoid fever
perse as you are treated completely. However looking at your health completely, I would recommend you to reduce alcohol intake.
Hope this answer is clear and useful.
Wish you good health.
