The study examined the association between weekly mean temperature and influenza cases across 122 countries/regions (2014-2019) using a distributed lag non-linear model (DLNM). We analyzed 3145206 of overall (Flu-All), with A (Flu-A) B (Flu-B) accounting for 73.49% 26.51%, respectively. Within 2 weeks, Flu-All incidence demonstrated bimodal relationship, peak relative risks (RR) 6.02 (95% CI: 1.92-20.77) at -8 ℃ 3.08 1.27-7.49) 22 ℃. Flu-A exhibited similar pattern, RRs 3.76 2.39-5.91) 2.08 1.55-2.80) Flu-B single risk 1 (RR = 4.48, 95% 1.74-11.55). Subgroup analyses climate zones revealed variations: tropical peaked 12 1.37, 1.08-1.74), while dry temperate highest -5 ℃, 4.49 2.46-7.15) 5.23 3.17-8.64), Cold 5.96, 3.76-9.43). transmission (ITZs) Africa showed higher 6 ℃-14 Asia below 3 Europe distinct peaks -1 (Eastern), (Southwest), -20 (Northern).

Introduction SARS-CoV-2 is primarily transmitted by direct contact between infected individuals, but other factors, such as meteorology, can affect mortality rates and the incidence of this disease. The purpose study was to examine impact meteorological factors on COVID-19 in a center Iran. In fact, sought pursue two main goals: first, find climate air pollutant risk that seem be related people's respiratory conditions, their effect number daily cases deaths caused COVID-19, second one use time series regression model appropriate for data instead one-variable models. Material Methods Data collected over modeled forecasted using methods. It common models based single response variable, Autoregressive Integrated Moving Average (ARIMA) model. addition confirmed we have also considered indices independent variables. ARIMAX method applied case. Results fitted five lags (lag days). found average temperature lag 10 relative humidity 7 were COVID-19. visibility had significant inverse relationship with 14 7; observed cases, so 3, decreased, increased. Conclusion seems some severe storms, severity disease should especially heart patients. Thus, necessary measures taken reduce infection it.

.In this study, we assessed the impact of satellite-based Land Surface Temperature (LST) and Air (AT) on covid-19. First, spatio-temporally kriged LST applied bias correction. The epidemic shape, timing, size were compared after before adjusting for predictors. Given non-linear behavior a pandemic, semi-parametric regression model was used. In addition, interaction effect between predictors season assessed. Before predictors, peak happened at end hot season. After adjusting, it attenuated slightly moved forward. Moreover, Attributable Fraction (AF) Peak to Trough Relative (PTR) % 23 (95% CI; 15, 32) 1.62 (95%CI; 1.34, 1.97), respectively. We found that temperature might have changed seasonal variation However, given large uncertainty variables, hard provide conclusive evidence in region studied.

Since the (Covid-19) pandemic outbreak, questioning regarding climate and incident of Covid-19 infection rates has been debated, while there is no clear research evidence until now in Iran. This study focused on investigating association between cases demographic –meteorological factors arid semi-arid zones Iran (from March 1, 2020, to January 31, 2022) by analyzing with Via Poisson negative binomial regression. As a result, incidence rate both hospitalization mortality reached peaks summer followed autumn. Interestingly, are associated humidity, temperature, wind seasonally monthly, but just wind. In conclusion, result demonstrated that demographicand meteorological factorsare positively negatively cases. Therefore, identifying environmental contributing excess can help prevent future waves Iranian zone.
