Climate indicators and the impact on morbidity and mortality of acute respiratory infections

Abstract

The fire incidences in Campo Grande have been a serious environmental problem. Therefore, this study is aimed at studying the trend of acute respiratory infections (IRA) from the year 2011 to 2017 and to correlate it with precipitation, wind speed, relative humidity, maximum and minimum temperatures, surface ozone concentration, optical depth, index of clarity and the number of outbreaks of fires. IRA records were obtained through DATASUS; the record of burn outbreaks at the National Institute for Space Research and the ozone concentration at the Federal University of Mato Grosso do Sul. There exists a positive and significant correlation between the number of burn outbreaks, wind velocity, ozone concentration, and optical depth with rates of hospitalizations for IRA. Also, a negative correlation exists between precipitation parameters, relative humidity, maximum and minimum temperatures. These results show the intensity of the problem and the great impact on the respiratory health of the population as well as on the economy due to increase in the number of hospitalizations and days of treatment.Climate can affect air quality, which in turn can affect climate change and both can directly or indirectly affect health. The two main effects of climate change on air quality are degrading the processes of removal (dispersion, precipitation) and atmospheric chemistry [3]. These will affect primary pollutants (e.g soot particles) and secondary pollutants (e.g ozone and sulfate particles) [4,5].The lack of information regarding the relation between atmospheric pollution and climatic variations and respiratory infections in the cities instigated the verification of this relation. Thus, the objective of the present study is to verify the relationship between climatic variation and atmospheric pollution, on one side, and the number of hospitalizations due to respiratory diseases in the population of the city of Campo Grande-MS.Climate indicators and the impact on morbidity and mortality 7

Variations in the tropospheric concentration of NO2 in the central west of Brazil, MS, and their relationship with the COVID-19

“…The lower the levels of air pollution, the better the health of the population with cardiovascular and respiratory diseases, both in the long and short term. Therefore, it is very important to constantly monitor air quality to assess the impact of pollutants on human health (Souza and Da Silva Santos 2020 ; Souza et al 2018a , 2018b ).…”

This study will focus on the state of Mato Grosso do Sul (MS), in the Midwest region of Brazil, based on the largest cities (Campo Grande, Dourados, Três Lagoas, Corumbá, Coxim, Porto Murtinho, Ponta Porã, and Chapadão do Sul) (IBGE 2021).…”

Modeling of hospital admissions for respiratory diseases as a function of probability distribution functions

“…Sensitive and vulnerable groups, such as pregnant women, children, the elderly, and those who already suffer from respiratory illnesses and other serious diseases, or from low-income groups, are especially affected by climatic variation. Studies have shown that the number of respiratory diseases in children and the elderly increases due to the higher concentrations of air pollution (Souza, et al, 2018c;Souza, et al, 2018d;Souza, et al, 2017;Santos, et al, 2017;Braga, et al, 1999;Braga, et al, 2001;Viegi, et al, 2009). According to these studies, children are more susceptible because they need twice the amount of air inhaled by adults, and the elderly are more affected because of their weakened immune and respiratory systems and have been exposed to a large amount of air pollution in all your life.…”

Análise em séries temporais da radiação solar na Cidade do Recife/PE

“…Nas pesquisas ligadas aos problemas ambientais, variáveis climáticas como umidade relativa do ar, temperatura e a precipitação pluviométrica têm sido amplamente estudadas e relacionadas à saúde da população (Peng, Xiao-Ming, & Qi-Yong, 2020;Santos et al, 2017;Sobral et al, 2020;Souza et al, 2018). Diante disso, o estudo de radiação solar se faz importante, pois a radiação solar está ligada as variações sazonais da temperatura (Spokas, 2006).…”
