“…A review for cold exposure and immune function reported that lower temperature may repress the immune function (Shephard and Shek, 1998). In particular, our previous finding suggested that the phagocytic function of pulmonary alveolar macrophages declined under cold stress in vitro experiment (Luo et al, 2017). Breathing cold air can lead to bronchial constriction, which may promote susceptibility to pulmonary infection (Martens, 1998).…”

Generalized additive model was applied to explore the effect of temperature, humidity and diurnal temperature range on the daily death counts of COVID-19. There were 2299 COVID-19 death counts in Wuhan during the study period. A positive association with COVID-19 daily death counts was observed for diurnal temperature range (r = 0.44), but negative association for relative humidity (r = −0.32). In addition, one unit increase in diurnal temperature range was only associated with a 2.92% (95% CI: 0.61%, 5.28%) increase in COVID-19 deaths in lag 3. However, both 1 unit increase of temperature and absolute humidity were related to the decreased COVID-19 death in lag 3 and lag 5, with the greatest decrease both in lag 3 [−7.50% (95% CI:

Impact of air pollution and outdoor temperature on the rate of chronic obstructive pulmonary disease exacerbations.Folia Medica 2017;59(4): 423-9. doi: 10.1515/folmed-2017-0053 Background: Environmental pollution can be one of the main risk factors for acute exacerbations of chronic obstructive pulmonary disease (COPD). Aim: To study the relationship between air pollution, outdoor temperature and exacerbations of COPD. Materials and methods: COPD patients (n=1432) were followed up for one year. The levels of particulate matter up to 10 μm (PM 10 ), nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ) and outside temperatures were collected from the Environmental Agency database.Results: A total of 309 acute COPD exacerbations (AECOPD) were recorded in the analysis. The daily mean concentrations of PM 10 were found to correlate signifi cantly with the daily mean concentrations of NO 2 and SO 2 (ρ 0.34 and ρ 0.49, respectively; p=0.0001). The negative correlations between the daily mean temperature and the daily mean levels of PM 10 , NO 2 and SO 2 were also signifi cant (ρ -0.44, ρ -0.11, and ρ -0.37, respectively; p=0.0001). The daily number of AECOPD correlated with the mean levels of PM 10 in the previous six days (ρ 0.14; p=0.02) and the lower outdoor temperature (ρ -0.2; p=0.001). The negative correlation between the daily number of AECOPD and the mean daily temperature was stronger in days with levels of PM 10 above 50 μg/m 3 (ρ -0.3 p=0.02 vs. ρ -0.18 p= 0.01). Conclusion: Lower daily mean temperatures were associated with the levels of air pollutants. The level of PM 10 correlated with the levels of the other air pollutants. The daily number of AECOPD was found to correlate weakly, but signifi cantly with the mean level of PM 10 in the previous six days. BACKGROUND

“…A time experiment conducted in Shanghai on the influence of DTR on chronic obstructive pulmonary disease (COPD) mortality clarified that, for every 1°C increase in the 4 days for DTR, COPD mortality increases by 1.25% ( 73 ). In an in vitro report on the effect of cold on immunity, Luo et al ( 74 ) explained that due to the reduction in the phagocytic ability of macrophages present in alveolus beneath the cold temperature, cold impairs immunity functions ( 74 ). Cold air respiration enhances the constriction of bronchus and in turn promotes the tendency for pulmonary infection ( 75 ).…”

The medical authority in China, especially in Wuhan city, reported on December 2019 a large number of highly fatal, rapidly spreading viral pneumonia caused by an unknown coronavirus. The common history of all the patients was their visiting a Wuhan's whole food store, where live animals and seafood are sold. Irrespective of the efforts of the Chinese authorities, the virus spread rapidly all over the world by travelers, provoking widespread attention by the media and panic. Many previous coronavirus epidemics had been recorded, such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), and the recently newly discovered epidemic is named coronavirus disease of 2019 (COVID-19). This disease is caused by SARS Coronavirus-2 (SARS-CoV-2), and this virus is antigenically related to the SARS virus (SARS-CoV), which had been detected in 2002, depending on clinical, serological, and molecular findings. There is rapid competition among the researchers to discover the source of the virus, understand the mechanism of the disease development, establish treatment strategies, and determine the factors affecting the incidence of infection and severity of the disease, and focus on the production of a vaccine. Coronaviruses are a group of single-stranded, positive-sense RNA genome viruses; its genome length varies from 26 to 32 kb. Coronavirus causes mild to severe respiratory disorders. In December 2019, several cases of pneumonia of unknown causes were found in Wuhan city, which is located in the Hubei province in China. Chinese health authorities investigated the problem and found that a new virus caused such infection and, using next-generation sequencing, found the 2019 novel coronavirus (2019-nCoV). It has been transferred from humans to humans and animals to humans (zoonotic). Coronaviruses cause multiple respiratory problems, varying from common cold to severe infections such as SARS. General symptoms of infection include fatigue, cough, and breathing problems such as shortness of breath, as described by World Health Organization. Serious cases may result in pneumonia, renal failure, and even death. We address current information about the new SARS Coronavirus-2 as well as the COVID-19 disease caused by it in this review.
