Several factors contribute to the emergence and re-emergence of diseases:
Human-animal interactions: Increased contact with wildlife can result in zoonotic diseases spilling over into human populations. Climate change: Altered weather patterns can expand the habitats of vectors like mosquitoes, increasing the spread of diseases such as malaria and dengue. International travel and trade: These activities can quickly disseminate pathogens across continents. Antimicrobial resistance: The misuse and overuse of antibiotics have led to the emergence of resistant strains of bacteria. Public health infrastructure: Gaps in healthcare systems can exacerbate the spread and impact of infectious diseases.
