EMERGING AND RE-EMERGING INFECTIOUS DISEASE PROGRAM

In the recent past, the Philippines has seen many outbreaks of emerging infectious diseases and it continues to be susceptible to the threat of re-emerging infections such as leptospirosis, dengue, meningococcemia, tuberculosis among. The current situation emphasizes the risks and highlights the need to improve preparedness at local, national and international levels for against future pandemics. New pathogens will continue to emerge and spread across regions and will challenge public health as never before signifying grim repercussions and health burden. These may cause countless morbidities and mortalities, disrupting trade and negatively affect the economy.

There are several social determinants contributing to the emergence of novel infectious diseases and resurgence of controlled or eradicated infectious diseases in our country. These contributing factors are namely: (1) Demographic factors like the population distribution and density, (2) international travel/ tourism and increased OFWs, (3) Socio-economic factors and (4) Environmental factors. The latter includes our country’s vulnerability to disasters, increased livestock production, man- made ecological changes or industries and lastly the urbanization which encroach and destroy the animal habitats.
