La enfermedad de manos, pies y boca está relacionada con la humedad y la temperatura (Int J Dermatol)
- Noticias Médicas
Investigadores de la Universidad de California San Francisco (Estados Unidos) han hallado una posible relación entre la enfermedad de manos, pies y boca con la temperatura y la humedad.
Se trata de una infección viral infantil común que suele aparecer en los meses más cálidos del verano, si bien los científicos, cuyo trabajo ha sido publicado en el International Journal of Dermatology, no han encontrado que tenga también un vínculo con la luz solar, el viento o la lluvia.
A juicio de los expertos, sus resultados sugieren que el calentamiento global puede afectar las tasas de enfermedad de manos, pies y boca, tanto al prolongar la duración de los brotes durante las temporadas altas como al aumentar la probabilidad de transmisión de enfermedad de manos, pies y boca a lo largo del año.

Abstract
Hand, foot, and mouth disease (HFMD) is an enterovirus‐mediated condition that predominantly affects children under 5 years of age. The tendency for outbreaks to peak in warmer summer months suggests a relationship between HFMD and weather patterns. We reviewed the English‐language literature for articles describing a relationship between meteorological variables and HFMD. Seventy‐two studies meeting criteria were identified. A positive, statistically significant relationship was identified between HFMD cases and both temperature (61 of 67 studies, or 91.0%, reported a positive relationship) [CI 81.8–95.8%, P = 0.0001] and relative humidity (41 of 54 studies, or 75.9%) [CI 63.1–85.4%, P = 0.0001]. No significant relationship was identified between HFMD and precipitation, wind speed, and/or sunshine. Most countries reported a single peak of disease each year (most commonly early Summer), but subtropical and tropical climate zones were significantly more likely to experience a bimodal distribution of cases throughout the year (two peaks a year; most commonly late spring/early summer, with a smaller peak in autumn). The rising global incidence of HFMD, particularly in Pacific Asia, may be related to climate change. Weather forecasting might be used effectively in the future to indicate the risk of HFMD outbreaks and the need for targeted public health interventions.
