“…In recent decades, much attention in the field of infectious diseases has been focused on global warming or climate change [32, 34, 35, 44, 45]. Many have speculated that warmer temperatures could increase many different infections, especially potentiating the spread of vector-borne disease, as vectors spread to new locations when temperatures rise (e.g., tick borne diseases in Canada)[32, 44–46].…”

Warmer weather as a risk factor for hospitalisations due to urinary tract infections

SUMMARY The incidence of urinary tract infections (UTIs) is seasonal, and this seasonality may be explained by changes in weather, specifically, temperature. Using data from the Nationwide Inpatient Sample, we identified the geographic location for 581813 hospital admissions with the primary diagnosis of a UTI and 56630773 non-UTI hospitalizations in the United States. Next, we used data from the National Climatic Data Center to estimate the monthly average temperature for each location. Using a case-control design, we modeled the odds of a hospital admission having a primary diagnosis of UTI as a function of demographics, payer, location, patient severity, admission month, year and the average temperature for the admission month. We found, after controlling for patient factors and month of admission, the odds of a UTI diagnosis increased with higher temperatures in a dose-dependent manner. For example, relative to months with average temperatures of 5–7.5°C, an admission in a month with an average temperature of 27.5–30°C has 20% higher odds of a primary diagnosis of UTI. However, in months with extremely high average temperatures (above 30°C), the odds of a UTI admissions decreases, perhaps due to changes in behavior. Thus, at a population level, UTI related hospitalizations are associated with warmer weather.

“…Many infections are seasonal [30]; many are related to weather [31–33]; and some of these are possibly related to changes in climate [34, 35]. Relative to other infections, there are few investigations regarding the seasonality and associations between weather and UTIs.…”

“…Temperatures greater than 34°C (extreme temperature) negatively affect the survival of malaria vectors, parasites, and, invariably, the transmission rate [17]. A shift in the distribution of vectors into nonendemic areas is expected as global temperature increases so that an increase in malaria incidence is expected in malaria-endemic areas with lower temperatures, while a decline in incidence is expected in regions at temperatures beyond the transmission peak (provided all other factors remain constant and do not change) [18,19].…”

Optimal Control and Temperature Variations of Malaria Transmission Dynamics

Malaria is a Plasmodium parasitic disease transmitted by infected female Anopheles mosquitoes. Climatic factors, such as temperature, humidity, rainfall, and wind, have significant effects on the incidence of most vector-borne diseases, including malaria. The mosquito behavior, life cycle, and overall fitness are affected by these climatic factors. This paper presents the results obtained from investigating the optimal control strategies for malaria in the presence of temperature variation using a temperature-dependent malaria model. The study further identified the temperature ranges in four different geographical regions of sub-Saharan Africa, suitable for mosquitoes. The optimal control strategies in the temperature suitable ranges suggest, on average, a high usage of both larvicides and adulticides followed by a moderate usage of personal protection such as bednet. The average optimal bednet usage mimics the solution profile of the mosquitoes as the mosquitoes respond to changes in temperature. Following the results from the optimal control, this study also investigates using a temperature-dependent model with insecticide-sensitive and insecticide-resistant mosquitoes the impact of insecticide-resistant mosquitoes on disease burden when temperature varies. The results obtained indicate that optimal bednet usage on average is higher when insecticide-resistant mosquitoes are present. Besides, the average bednet usage increases as temperature increases to the optimal temperature suitable for mosquitoes, and it decreases after that, a pattern similar to earlier results involving insecticide-sensitive mosquitoes. Thus, personal protection, particularly the use of bednets, should be encouraged not only at low temperatures but particularly at high temperatures when individuals avoid the use of bednets. Furthermore, control and reduction of malaria may be possible even when mosquitoes develop resistance to insecticides.

“…Climate variability and change pose severe threats to humanity worldwide. Variations in climate, either at the micro or macro-geographical level influence the survival, reproduction, transmission of disease agents and vectors, and their interaction with the geophysical factors associated with climate such as, precipitation, humidity, ambient and water temperature (Nkuo-Akenji et al, 2006;de Souza et al, 2012;Alemayehu et al, 2015). One of the major health concerns regarding climate variability is the increased prevalence of malaria across the globe especially in the tropics.…”

Climate variability and change is a major driver of infectious diseases around the world. This study sought to investigate the role of climate variability on the emergence of malaria in the North West region of Cameroon. Both biophysical and socio-economic data were collected for this study. Biophysical data, mainly secondary, was collected from meteorological stations (rainfall and temperature data) and hospitals (malaria morbidity and mortality statistics) in the study area. Socio-economic data were collected from primary sources, mainly, survey of households and hospitals, using semi-structured questionnaires. A total of 164 questionnaires were distributed amongst medical personnel and the general public (aged 18-70 years). Data obtained were analyzed using descriptive and inferential statistics. Findings revealed that patterns of fluctuation in climate parameters did not have a perfect match with rates of prevalence of malaria. However, some relatively significant correlation was found to exist between certain aspects of climate and rates of prevalence of malaria. It was noted that other drivers are involved in influencing rates of prevalence of malaria besides climate variability and change. Amongst the impacts of malaria prevalence on the population were high rates of morbidity and mortality. The population employed treated mosquito bed nets as the main coping strategy for fighting against malaria. The study recommends that the health sector should incorporate the phenomena of climate variability and change into its policy framework, and more research should be conducted to assess other drivers of malaria prevalence in north western Cameroon.
