DENGUE:A Climate Change Epidemic

     Dengue is now invading the whole nation.Hundreds  of thousands of dengue cases are reported nationwide every year.One of the epidemiologists of department of health(DOH)stressed that the emerging pattern is that dengue disease  is plaguing the country all year around.
     Dengue is one of the water borne diseases that provides scientific evidence that global warming is changing the seasonal patterns of infectious disease,according to scientists.this is because the virus itself and mosquitoes that carry the virus are known to be sensitive ti climate changes.In the past decades ,peaks were observed only during the wet season,female mosquitoes which lay their  eggs  in dirty open containers can survive and transmit virus to human.
     There are two kinds of mosquitoes,Stegomyia Aegypti and Stegomyia Albopictus(formerly known as Aedes)carry the four stains of dengue virus called sterotypes.Below are the symtoms and signs  of dengue;     

• Rapidly increasing fever
• Nausea and vomiting
• Loss of appetite
• Faint Rash
• Deep muscles Aches
• Joint Pains and pains behind the eyes    

It's not only during El Nino and La Nina the dengue epidemics track climate variations.dengue epidemics have consistently followed temperature and rainfall patterns in the Philippines  based on the studies.Also the seasonal reversal    of El Nino and La Nina weather event has an effect on how the mosquitoes can go and how long they can transmit the virus to human.
