Good & bad get together: Inactivation of SARS-CoV-2 in particulate matter pollution from different fuels

We publish a new interdisciplinary research article in the journal Science of the Total Environment.

Abstract: Air pollution and associated particulate matter (PM) affect environmental and human health worldwide. The intense vehicle usage and the high population density in urban areas are the main causes of this public health impact. Epidemiological studies have provided evidence on the effect of air pollution on airborne SARS-CoV-2 transmission and COVID-19 disease prevalence and symptomatology. However, the causal relationship between air pollution and COVID-19 is still under investigation. Based on these results, the question addressed in this study was how long SARS-CoV-2 survives on the surface of PM from different origin to evaluate the relationship between fuel and atmospheric pollution and virus transmission risk. The persistence and viability of SARS-CoV-2 virus was characterized in 5 engine exhaust PM and 4 samples of atmospheric PM10. The results showed that SARS-CoV-2 remains on the surface of PM10 from air pollutants but interaction with engine exhaust PM inactivates the virus. Consequently, atmospheric PM10 levels may increase SARS-CoV-2 transmission risk thus supporting a causal relationship between these factors. Furthermore, the relationship of pollution PM and particularly engine exhaust PM with virus transmission risk and COVID-19 is also affected by the impact of these pollutants on host oxidative stress and immunity. Therefore, although fuel PM inactivates SARS-CoV-2, the conclusion of the study is that both atmospheric and engine exhaust PM negatively impact human health with implications for COVID-19 and other diseases.

The Role of the Wild Boar Spreading African Swine Fever Virus in Asia

New research article published in Frontiers in Veterinary Science journal.

Abstract: African swine fever (ASF) is a highly lethal infectious disease in naïve populations of domestic pigs and wild boar. In Asia, from the first outbreak in August 2018 until the end of November 2021, ASF has been reported in Asian countries. The ASF virus (ASFV) circulation in domestic pigs is considered the main problem in Asia. On the other hand, there are very few reports of ASF in wild boar. However, considering the high wild boar density within the same area of backyard domestic pig farms in Asia, the occurrence of ASFV infection in wild boar may be underestimated. The role of the wild boar in other ASF epidemiological scenarios, such as Europe, is key for the maintenance and transmission of the disease. Hence, we performed a preliminary study estimating the extent of ASFV infection in the Asian wild boar population. The potential risk area of ASF infected wild boar was calculated based on the habitat suitability for wild boar, the kernel density of ASF notification in backyard farms and wild boar, and the ASFV transmission rate of wild boar. As a result of the analysis, high, medium, and low-risk areas were identified throughout southeast and east Asia. The highest risk area was detected in China, followed by Myanmar, far east Russia, Thailand, Vietnam, Laos, Cambodia, and the Philippines. This study shows hot spots where a high risk of infection in wild boar is most likely to occur, helping to control ASF.
