Why communicable diseases getting worst?

Communicable diseases are worsening due to factors such as increased global travel, which facilitates the rapid spread of pathogens across borders, and urbanization, which creates densely populated areas where diseases can thrive. Additionally, antibiotic resistance is growing as a result of overuse and misuse of medications, making infections harder to treat. Environmental changes, including climate change, also contribute by altering the habitats of vectors like mosquitoes, leading to the spread of diseases. Lastly, public health challenges, such as inadequate vaccination coverage and healthcare access, further exacerbate the situation.
