“…Approximately 85 % of outpatient visits of respiratory diseases are acute upper respiratory infections (ICD9 CM 460-466) and 9.8 % of patients are for pneumonia and influenza in Taiwan (Department of Health 2011). Therefore, the finding in this study agrees with previous reports that higher risks of respiratory infections are associated with low temperatures (Falagas et al 2008;Makinen et al 2009;Liao et al 2009;Lin et al 2013b). Lin et al (2009) evaluated the associations between hospital admissions for respiratory diseases and extreme high temperature in New York City.…”

“…In addition, Wong et al (2006) have also identified NO 2 with the greatest effects, followed by O 3 on acute upper respiratory infections. However, Lin et al (2013b) have recently related lower temperature, instead of respiratory viruses and ambient air pollutants, to the greatest risk change of outpatient visits for acute upper respiratory infections in Taipei, Taiwan.…”

“…The covariate of "daily average temperature" was set at natural cubic spline (NS) in the DLNMs. The delayed effect of temperature was evaluated and summarized for lag 0 to lag 7 (Lin et al 2013b, c). Because of the non-linear effect of average temperature, the relative risk of outpatient visits per 1°C temperature change would not be favorably reported.…”

“…Lack of indoor heat is significantly associated with increased health risks in the cold environment (Anderson and Bell 2009;Aylin et al 2001). Extreme cold has been associated with hospital admissions for respiratory diseases in some Asian cities (Wang et al 2012;Ma et al 2011;Lin et al 2013b).…”

This study evaluated the risk of outpatient visits for respiratory diseases, asthma, and chronic airway obstruction not elsewhere classified (CAO) associated with ambient temperatures and extreme temperature events from 2000 to 2008 in Taiwan. Based on geographical and socioeconomics characteristics, this study divided the whole island into seven areas. A distributed lag non-linear model was used to estimate the area-disease-specific cumulative relative risk (RR), and random-effect meta-analysis was used to estimate the pooled RR of outpatient visits, from lag 0 to lag 7 days, associated with daily temperature, and added effects of prolonged extreme heat and cold for population of all ages, the elderly and younger than 65 years. Pooled analyses showed that younger population had higher outpatient visits for exposing to low temperature of 18 °C, with cumulative 8-day RRs of 1.36 (95% confidence interval (CI) 1.31-1.42) for respiratory diseases, 1.10 (95% CI 1.03-1.18) for asthma, and 1.12 (95% CI 1.02-1.22) for CAO. The elderly was more vulnerable to high temperature of 30 °C with the cumulative 8-day RR of 1.08 (95% CI 1.03-1.13) for CAO. Elevated outpatient visits for all respiratory diseases and asthma were associated with extreme heat lasting for 6 to 8 days. On the contrary, the extreme cold lasting more than 8 days had significant negative association with outpatient visits of all respiratory diseases. In summary, elderly patients of respiratory diseases and CAO are vulnerable to high temperature. Cold temperature is associated with all types of respiratory diseases for younger patients.

“…High temperatures or heat can cause fatigue in humans because the heat causes a lot of sweat to be released, so it becomes dehydrated. Likewise with children and toddlers can be affected by flu, cough, runny nose, fever, respiratory tract disorders, colds, digestive disorders, allergies, and the most dangerous is Upper Respiratory Tract Infection [18]. Also, the increase in environmental temperature will also affect the impact of air pollution, especially in urban areas and affect individuals with chronic diseases such as heart disease, asthma and other respiratory diseases [19].…”

Infection is the entry and proliferation of infectious agents in the tissues of the human body which results in cell damage or pathological tissue. The respiratory tract is an organ starting from the nose to the alveoli and its adnexal organs such as the sinuses, middle ear cavity, and pleura. The research used was descriptive observational research with an ecological time trend study. To the analysis, data was the Pearson correlation. This study aims to see the correlation between Climate Variability and the Incidence Rate of Acute Respiratory Infection in the Kendari City Region in 2014-2018. The data used are Climate Variability (Humidity, Minimum Temperature, Average Temperature, Maximum Temperature, and Rainfall), Population data, and ARI Case in Kendari City 2014-2018. The results of this study indicate that Humidity (%) r=-0.306 Medium correlation and negative pattern, Minimum Temperature (oC) r=0.494, Average Temperature (oC) r=0.232 no correlation, Maximum Temperature (oC) r=0.700 Correlation of strong and positive pattern correlation, and Rainfall (mm) r=-0.612 Relationship of strong correlation and negative pattern.

IMPORTANCE Several studies reported an association between peritonsillar abscess formation and climate conditions, including seasonal changes; however, the results were inconsistent.OBJECTIVE To evaluate the association between meteorological conditions and/or air pollution and peritonsillar abscess formation. DESIGN, SETTING, AND PARTICIPANTSIn this nested case-control study, 3819 participants with peritonsillar abscesses were matched (1:4) for age, sex, income, region of residence, hypertension, diabetes, and dyslipidemia with 15 276 control participants. The Korean Health Insurance Review and Assessment Service-National Sample Cohort (HIRA-NSC) data from 2002 through 2013 were used. EXPOSURES AND MAIN OUTCOMES AND MEASURESThe meteorological data included the mean daily temperature (°C), highest daily temperature (°C), lowest daily temperature (°C), daily temperature difference (°C), relative humidity (%), spot atmospheric pressure (hPa), sulfur dioxide ([SO 2 ], parts per million [ppm]), nitrogen dioxide (NO 2 , ppm), ozone (O 3 , ppm), carbon monoxide (CO, ppm), and particulate matter less than 10 μg (PM 10 , μg/m 3 ) for the previous 14 days, 10 days, 7 days, 5 days, or 3 days before the matched index date. These factors were measured in 94 or 273 locations hourly. The crude and adjusted odds ratios (aORs) and 95% confidence intervals (CIs) of meteorological data for peritonsillar abscess formation were analyzed using unconditional logistic regression analysis. Subgroup analyses were conducted according to age and sex. RESULTSThe male to female ratio of study participants was 1.43 (11 260 to 7835). Because the age groups were classified using 5-year intervals, the mean age could not be defined. The mean differences of NO 2 and PM 10 concentrations for the 14 days between peritonsillar abscess group and control group were 1.78 ppb (95% CI, 1.47-2.09) and 1.33 μg/m 3 (95% CI, 0.67-1.99), respectively. The aORs of NO 2 (0.1 ppm) and PM 10 (10 μg/m 3 ) during the 14 days prior to the index date for peritonsillar abscess formation were 12.8 (95% CI, 8.4-19.5) and 1.04 (95% CI, 1.02-1.06), respectively. The other meteorological conditions did not reach statistical significance.CONCLUSIONS AND RELEVANCE Peritonsillar abscess formation was associated with high concentrations of NO 2 and PM 10 .
