Blood loss and shock: how dangerous is the new Marburg virus and will it reach Russia? More than 27 cases of Marburg hemorrhagic fever have been recorded in Rwanda, Africa. Nine of these resulted in death. Hemorrhagic fever is a group of viral diseases transmitted through insect bites or contact with infected animals or people. The World Health Organization (WHO) has assessed the risk of this outbreak as high on a national and regional level, but the chances of it turning into a pandemic are currently low. The carrier of the dangerous Marburg virus is the Egyptian fruit bat, also known as the Nile flying fox. It is found in Africa and several regions of the Middle East, including Syria, Turkey, Lebanon, and Israel. The disease is accompanied by chest pain, fever, rash, blood in stool, skin hemorrhages, and nosebleeds. Patients usually feel ill at the end of the first or the beginning of the second week, a period when death can occur. Infection can happen through the blood or other biological fluids of an infected person, as well as through contact with contaminated surfaces (clothing, bedding, etc.). Academician Gennady Onishchenko of the Russian Academy of Sciences does not rule out this possibility, given that Russians frequently travel abroad. To be prepared for any outcome, preventive measures must be taken. For instance, training doctors so they can correctly diagnose the disease if necessary. Moreover, in the future, due to climate changes, Russia may more frequently encounter exotic infections, including the Usutu virus.
