RESUMEN
18 cases of Chikungunya (or a very closely related virus) infection, a newly observed clinical entity in the Philippines, are presented. Diagnosis was established by serological studies consisting of hemagglutination-inhibition (HI) and complement fixation (CF) tests. (Summary)
RESUMEN
A total of 322 satisfactory blood sera, obtained from individuals with ages ranging from 5 months to 4 years in rural and urban areas, were serologically tested with hemagglutination-inhibition technique. Results showed that 25 percent and 50 percent of the infants (2 yrs and below) in rural and urban, respectively, contracted the disease and doubled at preschool ages when malnutrition was highest in the country. At school age, 69 percent and 76 percent of the children in rural and urban areas contracted the disease while 95-100 showed immunity at adolescence (13-17) in both areas.(Author)
RESUMEN
1. The onset of menstruation, menstrual cycle, duration of the flow, and the influence of physical exercise in 464 women students coming from 46 provinces inthe Philippines were studied2. The onset of menstruation occurs most frequently between twelve and fourteen years of age, the greatest number falling at thirteen years of age3. The average duration of the menstrual flow is from three to five days, and the most common interval between menses in 28 days4. Physical exercise has a variable influence upon individuals, personal adaptation being the controlling factor5. The onset of menstruation seems to be the same in all girls in the Philippines irrespective of whether they have come from the north or south. However, definite conclusions cannot be made on this matter owing to the insufficiency of representative materials at hand. (Summary and conclusions)
