###Human: My mom has throat pain while swallowing and fever since yesterday. Is it dengue? ###Assistant: Hello. Yes, it is certainly possible to have such a fever and it is likely she has an upper respiratory tract infection. I think whatever she is receiving is fine. Antibiotics will take at least 48 hours to act and initially, the infection is viral. So, antibiotics may not work for the initial two to three days. I think she should continue the same treatment. Hope this helps you. Get back if you have any doubts. For more information consult a general medicine physician online -->
