abstract = {In a world where everything has turned out to be more digital, finding reliable health information has become a challenge, and most people have to depend on unverified sources of information on the internet, resulting in misinformation and misinformed health choices. In this paper, we will design and develop a healthcare chatbot based on AI that will be able to provide relevant, accurate health advice in response to natural language queries. Using a combination of sophisticated natural language processing methods, which is a fine-tuned BERT model, and a structured geographical symptom-disease knowledge base, the system intelligently interprets queries provided by the user, including regional and seasonal variations, to provide reliable health advice. The retrieval mechanism uses semantic matching by cosine similarity to retrieve pertinent information using a large validated health database. Such a combined solution increases semantic knowledge, facilitates the regional awareness of the disease, and increases the accuracy of the response. Assessment of a wide range of health-related queries proves effectiveness of the system with great semantic alignment scores and strong intent recognition, therefore, exemplifying the prospects of integrating NLP models with local health information to deliver reliable health information.},
