“…The higher incidence of unintentional CO poisoning at lower temperatures may be the result of people closing doors and windows to keep warm at home, thus preventing air circulation and increasing indoor CO levels, especially with improper installation of household heating systems. This tendency of linear association between temperature and CO poisoning events was also observed in other studies ( 12 , 17 ), and may reflect the increasing probability of people staying indoors and using household heating systems as the weather gets colder.…”

“…Identifying risk factors is vital to developing appropriate precautions and weather-related factors have been considered one of the most important risk factors for acute CO poisoning. A previous study by Tiekuan Du et al in Beijing indicated that temperature was inversely correlated with the incidence of acute CO poisoning ( r = −0.467) ( 12 ). Another study from Roca-Barceló Aina et al in the UK also demonstrated clear seasonality in the incidence of acute CO poisoning ( 13 ).…”

“…For example, the climate of Taiwan is warm (mean annual temperature: 24.6°C), rainy (mean rainy days: 146 days) and humid (mean relative humidity: 79.43%), so the weather impacts on CO poisoning in Taiwan may differ from previous reports. In addition, previous studies have mostly explored the association between temperature changes and CO poisoning, while the influence of other important weather factors (e.g., relative humidity and wind speed) on this issue remains unclear ( 12 , 21 ). We therefore conducted this study to fill the knowledge gap and assist healthcare providers and policy makers to develop more strategies based on weather parameters to avoid intentional and unintentional CO poisoning.…”

Background: Carbon monoxide (CO) poisoning is the leading cause of poisoning death worldwide, but associations between CO poisoning and weather remain unclear.Objective: To quantify the influence of climate parameters (e.g., temperature, relative humidity, and wind speed) on the incidence risk of acute CO poisoning in Taiwan.Methods: We used negative binomial mixed models (NBMMs) to evaluate the influence of weather parameters on the incidence risk of acute CO poisoning. Subgroup analyses were conducted, based on the seasonality and the intentionality of acute CO poisoning cases.Results: We identified a total of 622 patients (mean age: 32.9 years old; female: 51%) with acute CO poisoning in the study hospital. Carbon monoxide poisoning was associated with temperature (beta: −0.0973, rate ratio (RR): 0.9073, p < 0.0001) but not with relative humidity (beta: 0.1290, RR: 1.1377, p = 0.0513) or wind speed (beta: −0.4195, RR: 0.6574, p = 0.0806). In the subgroup analyses, temperature was associated with the incidence of intentional CO poisoning (beta: 0.1076, RR: 1.1136, p = 0.0333) in spring and unintentional CO poisoning (beta: −0.1865, RR: 0.8299, p = 0.0184) in winter.Conclusion: Changes in temperature affect the incidence risk for acute CO poisoning, but the impact varies with different seasons and intentionality in Taiwan. Our findings quantify the effects of climate factors and provide fundamental evidence for healthcare providers to develop preventative strategies to reduce acute CO poisoning events.

“…Similarly, Salameh et al reported over half of CO poisoning in Jerusalem (1994Jerusalem ( -2006 to be attributable to faulty gas heaters in 292 hospital patients [13]. The association between fuel, heating and CO poisoning has been further established by emergency medical service data in Beijing, which identified elevated incidence of CO poisoning in winter months; 3,331 patients were recorded for CO poisoning between 2005 and 2007 in winter months, accounting for 88.4% of the study population [14].…”

Public Health Impacts of Exposure to Carbon Monoxide From Gas Appliances in UK Homes – Are We Missing Something?

Carbon monoxide (CO) is a colourless and odourless poisonous gas formed from the incomplete combustion of substances containing carbon. In the United Kingdom, over 22 million homes have mains or liquefied petroleum gas and consequently there is particular concern regarding potential CO poisoning resulting from malfunctioning domestic gas appliances. Although the number of reported cases of CO poisoning in the United Kingdom is relatively small, there is a high probability of misdiagnosis of the condition due to the ambiguous clinical symptoms of CO poisoning; incidence may therefore be much higher than currently reported. This review discusses the current knowledge on human health and toxicological effects following exposure to CO, focusing particularly on the public health impacts associated with gas appliances in UK homes. In determining the possibility of an underlying threat, the biological plausibility of misdiagnosis, in combination with reported cases, is discussed. The implication of misdiagnosis for public health treatment is also briefly summarised.

“…Indicating that carbon monoxide poisoning in cold months occur in high percentage and is related to the burning of coal for home heating. [11] In the United Arab of Emirates during the period 2007-2009, it was indicated the exclusive occurrence of carbon monoxide poisoning is in winter months. The reason was also the use of charcoal as a source of warmth in closed areas with disregard for safety precautions.…”

Background:Carbon monoxide (CO) is a highly poisonous, odorless, colorless and non-irritating gas. It is formed by incomplete combustion of carbon or carbonaceous material. Because burning under conditions with insufficient oxygen will prevent complete oxidation to carbon dioxide (CO2), carbon monoxide gas will be formed. When inhaled, it will prevent absorption of oxygen by combining with hemoglobin in the blood, forming carboxyhemoglobin, which result in secondary tissue hypoxia and cellular damage, hence the name "silent killer". Objectives:The three main objectives of the study are; (a) Measuring public exposure to CO producing sources among Saudis using social networking, in winter season for the year 2013-2014, (b) Assessing their awareness and knowledge towards the hazards of carbon monoxide (CO) poisoning produced by different means of heating, and (c) Determine the safety precautions applied to that regard. Methods:A cross sectional study was conducted online targeting, sample size of 634 Saudis from age of (16-50 years) who are using social networks, regarding: a) The public exposure to different CO producing sources, b) The public knowledge regarding symptoms, sources and risks, c) The safety precautions followed to prevent unintentional carbon monoxide poisoning Result:Based on our research, more than half of our sample size (53.94 %) were exposed to CO from different sources with difficulty in breathing being the most known symptom chosen by 75.10% of our sample, followed by headache and dizziness being the second with (57.10%) whilst only 11.70% chose seizures, which is the least symptom, selected. CO poisoning resulted in suffocation and death with 89.11% and 59.62% respectively being the most known risks. Burning coal or firewood was the highest selected source of CO with percentage of 88.60% however, only 4.70% thought refrigerators as a
