Impact of rotavirus and hepatitis A virus by worldwide climatic changes during the period between 2000 and 2013

Abstract

Enteric viruses are present in the environment as a result of the discharge of poorly or untreated wastewater. The spread of enteric viruses in the environment depend to human activities like stools of infected individuals ejected in the external environment can be transmitted by water sources and back to susceptible individuals for other cycles of illness. Among the enteric viruses Rotaviruses (RV) and Hepatitis A viruses (HAV) is the most detected in wastewater causing gastroenteritis and acute hepatitis. Therefore, it is of interest to climate change, mainly temperature and carbon Dioxide (CO2) variations, on Rotavirus and Hepatitis A as a model of enteric viruses present in the aquatic environment using computational modelling tools. The results of genetic ratio showed a negative correlation between the epidemiological data and the mutation rate. However, the correlation was positive between the temperature, CO2 increase, and the rate of mutation. The positive correlation is explained by the adaptation of the viruses to the climatic changes, the RNA polymerase of the RV induces errors to adapt to the environmental conditions. The simultaneous increase in number of infections and temperature in 2010 has been demonstrated in previous studies deducing that viral pathogenicity increase with temperature increase.

Environmental impacts on the transmission and evolution of COVID-19 combing the knowledge of pathogenic respiratory coronaviruses

“…Climate conditions, especially ambient temperature, precipitation and humidity, were connected with the survival, reproduction, distribution and abundance of the intermediate vectors, and the physiological conditions, immune responses and crowding occurrence of the specific hosts ( Monto, 2004 ; Campbell et al., 2015 ; Paz, 2015 ), thus increasing the outbreak risk of the epidemic of respiratory infectious diseases. Worldwide climate changes, mainly temperature and carbon dioxide (CO 2 ) variations, had the possibility to affect the mutation of rotavirus and hepatitis A virus ( Tarek et al., 2019 ). To date, the evidence on climatic influences on the evolution of respiratory CoVs has been still lacking.…”

SARS-CoV-2: Origin, Intermediate Host and Allergenicity Features and Hypotheses

“…In addition, the effect of meteorological factors on viral transmission and outbreak at the host population have not yet been determined. It was reported that extreme meteorological factors can accelerate the mutation of viruses [ 9 , 10 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. In this study, in order to find out the key climatic features of two coronavirus outbreaks in Wuhan and Guangdong in 2019 and 2002, respectively, we analyzed the climate data (mean temperature, maximum temperature, minimum temperature, precipitation, hours of sunshine, relative humidity) of Wuhan and Guangdong from 1951 to 2019.…”

“…Shellfish are known to accumulate human pathogens, such as human enteric viruses (e.g., rotavirus in mussels [ 52 , 53 ], enterovirus [ 32 , 54 ], HAV [ 26 , 55 ], and norovirus [ 27 , 56 , 57 ] in oysters).…”
