According to the World Health Organization, many of the world’s developed countries consider 65 years as the chronological age when people are considered “elderly,” while the United Nations uses the ages of 60 and above. However, in parts of sub-Saharan Africa and elsewhere the cutoff age is often lower such as 50 or 55 years.
This month, PLOS Neglected Tropical Diseases published a new study by Rowe et al. from Singapore on dengue fever in the elderly (> 60 years of age). Among their interesting findings were that the elderly had longer hospital admissions, and had higher rates of pneumonia and urinary infections. Overall, the elderly had more dengue hemorrhagic fever and severe dengue.
