Background: The mean age of dengue has been increasing in some but not all countries. We sought to determine the incidence of dengue virus (DENV) infection in adults and children in a prospective cohort study in the Philippines where dengue is hyperendemic.
Methodology/principal Findings: A prospective cohort of subjects ≥6 months old in Cebu City, Philippines, underwent active community-based surveillance for acute febrile illnesses by weekly contact.
Proper understanding of the long-term epidemiology of chikungunya has been hampered by poor surveillance. Outbreak years are unpredictable and cases often misdiagnosed. Here we analyzed age-specific data from 2 serological studies (from 1973 and 2012) in Cebu, Philippines, to reconstruct both the annual probability of infection and population-level immunity over a 60-year period (1952-2012).

- - A study in Cebu City, Philippines from 2012-2013 explored the prevalence of symptomatic and subclinical Chikungunya virus (CHIKV) infections, finding that subclinical cases were much more common, occurring at a ratio of 4.6:1 compared to symptomatic cases.
- - Of the 853 participants, the study identified 19 symptomatic infections and 87 subclinical infections, with the rate of subclinical infections varying significantly by age.
- - High baseline CHIKV antibody levels were found to provide complete protection against symptomatic infections, and genetic analysis revealed a close relationship between local strains and those found in Asia and the Caribbean.

The prevalence of Giardia and Cryptosporidium among 3,456 diarrheic patients corrected from May 2004 to May 2005 in the Philippines was determined. Of 133 (3.8%) positive samples, 69 (2.
