Introduction
The monsoon season brings much-needed relief from the scorching summer heat, but it also brings with it an increased risk of various diseases. The high humidity, stagnant water, and damp conditions create the perfect breeding ground for bacteria, viruses, and mosquitoes. As a result, illnesses like dengue, malaria, cholera, typhoid, and viral fevers become more common during this time.
Understanding these diseases, their symptoms, and preventive measures can help you stay healthy and enjoy the rainy season without falling ill.
