Most infectious diseases in template climates have seasonal pattern, that can be influenced by climatic, social and host factors.
To study the seasonal patterns of seven human infectious diseases in Chile.
Series of monthly cases of measles, whooping cough, scarlet fever, meningitis, diphtheria, typhoid fever and poliomyelitis were obtained from yearly reports of infectious disease of the Ministry of Health. Descriptive statistical parameters and multivariate methods were used to analyze data.
Diseases that have an enteric mode of transmission predominate in summer, independent of the type of agent (viral or bacterial) or presence of carriers. Diseases with a respiratory mode of transmission have two different patterns. Those without carriers (measles and whooping cough) predominate in spring and those with carriers (scarlet fever, diphtheria and meningitis) have a winter predominance.
This work confirms the seasonal variation of enteric and respiratory infectious diseases and defines patterns that can be useful for future studies.
在温带气候中,大多数传染病具有季节性模式,这可能受到气候、社会和宿主因素的影响。
研究智利七种人类传染病的季节性模式。
从卫生部传染病年度报告中获取麻疹、百日咳、猩红热、脑膜炎、白喉、伤寒和脊髓灰质炎的月度病例系列。使用描述性统计参数和多变量方法分析数据。
具有肠道传播方式的疾病在夏季占主导地位,与病原体类型(病毒或细菌)或携带者的存在无关。具有呼吸道传播方式的疾病有两种不同模式。无携带者的疾病(麻疹和百日咳)在春季占主导地位,有携带者的疾病(猩红热、白喉和脑膜炎)在冬季占主导地位。
这项工作证实了肠道和呼吸道传染病的季节性变化,并确定了可用于未来研究的模式。
