“…The results are compatible with the report of Chumpolbanchorn et al, (2006) who indicated that the infectivity of the H5N1 Shahid et al, (2009) who found no deleterious effect on the virus replicating ability after 60 minutes of UV light exposure. In another study by Fasina et al, (2010), the exposure to UV light up to 180 minutes was not found to have any effect on the HPAI H5N1 virus ability to haemagglutinate chicken RBC, pathogenicity in eggs and haemagglutination titre. Effectiveness of UV light depends on various factors such as presence of organic matter, humidity, cleanliness of UV light bulbs, age of UV lamps, and the pattern and duration of use of the UV light for disinfection (Burgener, 2006;Tseng and Li, 2007).…”

“…Under colder conditions, the lipid bilayer will harden into a rubber-like shape to protect the virus, Therefore, most enveloped viruses tend to exhibit strong seasonality [10]. Past research found that influenza viruses have a certain sensitivity to ultraviolet radiation [11]. Consequently, it has been assumed that viruses ejected into the atmosphere experience lower inactivation rates during seasons with reduced solar activity on sun, regular with moderate epidemics occurring during the winter and tropical epidemics during the raining seasons [12][9].…”

In late 2019 and in Wuhan, a new disease appears, consider as an extension of SARS-COV2 epidemic. This epidemic virus has configured a danger to global health. We studied the effect of some atmospheric elements in Iraq with a number of (COVID-19) infections. In this study daily infections in three regions of Iraq compares with (Tmax-Tmin) and (RH) observed in stations Mosul (represent north region), Baghdad and Rutba (represent middle regions), and Basra (represent south region). It's found that increasing the difference between Tmax and Tmin means more infections, except for the northern province. As for the relative humidity, it is inversely proportional to infections with the correlation coefficient R = -0.6 in Baghdad station, and in the southern province with R = -0.32, and the opposite occurs in the northern province. The results also indicate that increasing the relative humidity to more than 70% was effective in increasing the infections. Solar radiation was studied over the city of Baghdad and its effect on infections because solar radiation contains a large proportion of ultraviolet rays that killed many viruses, the study indicates an inverse relationship because most of the patients are infected in the shade and there is no clear relationship.
