The relationship between child asthma admissions and biometeorological factors was investigated over a 16‐month period. No relationship was found with many commonly suspected precipitants such as temperature, humidity and wind. There was however a strong association with rainfall (P<<0.001). Associations occurred with low barometric pressure and counts of coloured basidiospores and green algae, but no significant relationship was found with grass pollen. 

Climate and aeroallergen levels in asthma: a 12 month prospective study.

The results of this study suggest that the effects of weather and aeroallergens on PEFR and asthma symptoms in this population are small, and that other causes need to be sought to account for variations in asthma severity and exacerbations.

Association of Weather Conditions with Childhood Admissions for Wheezy Bronchitis or Asthma in Athens

The results indicate a constant seasonal variability in asthma admissions among children in Athens, whereas relative humidity and atmospheric pressure are the more implicated meteorological variables for younger asthmatic children.

The environmental impact on the development of asthma

A sthma is a chronic disease of the respiratory system with a key point the shortness of breath due to a temporary airway stenosis, its main characteristics are: an increasingly assuming epidemic dimensions disease, its chronicity and unidentified pathogenesis.

Several dozen reports of epidemics of asthma during thunderstorms have been published during the past 20 years. It has been suggested that these epidemics may be explained by exposure of atopic

The Effect of Weather Variability on Pediatric Asthma Admissions in Athens, Greece

Findings showed that Hospital admissions for childhood asthma in Athens, Greece, is negatively correlated with discomfort index, air temperature and absolute humidity whereas there is a positive correlation with cooling power, relative humidity and wind speed.

The role of fungal spores in thunderstorm asthma.

The results support a relationship between thunderstorms and asthma, and suggest that the mechanism may be through increases in spores that exacerbate asthma.

Relationships Between Environmental Factors and Lung Function of Asthmatic Subjects in South East Queensland, Australia

Analysis of the association of outdoor air pollutant concentrations and air spora with the decrease in lung function of two groups of asthmatic subjects in the subtropical environment of South East Queensland, Australia indicates that the effect of ozone on peak expiratory flow in the allergic group can sometimes be confounded by air Spora effects.

Association of severe asthma attacks with weather, pollen, and air pollutants.

Increased levels of pollutants, especially NO2, were associated with attacks of asthma, but the explanation for this is unclear.

The role of air pollution and weather changes in childhood asthma.

High levels of ozone and carbon monoxide significantly correlated with the number, duration and the severity of asthmatic attacks, however, all the factors combined played only a minor role in the complex etiology of asthma.

Daily records of various parameters of asthma were correlated with levels of different air pollutants and such climatological factors as bad weather conditions and temperature changes, but all the factors combined played only a minor role in the complex etiology of asthma.


Children from the Melbourne metropolitan area with laboratory proven bronchial sensitivity to ryegrass pollen were selected for a clinical trial which was run concurrently with an aerobiological


The relationship between daily asthma attendance, weather parameters, spore count and pollen count.

Variation in climate factors and fungal spore counts are associated with variation in the asthma attendance rate in the Perth area between April and September.

Respiratory virus infections and aeroallergens in acute bronchial asthma.

The single precipitating factor most frequently associated with acute asthma was respiratory virus infection.

Respiratory viral infection in childhood. A survey in general practice, Roehampton 1967–1972

Rhinoviruses were more commonly isolated than any other agent and were frequently associated with wheezy bronchitis and the clinical features associated with infection were influenced by the type of agent but also by age and other host factors in the infected children.
