The spread and severity of the disease. Scientists say the discovery of these virus clusters has led to a better understanding of how the virus is transmitted, its methods, and its strong infectivity, and provides an improved reference for existing antiviral drug development efforts against only individual virions.
Dr. Nihal Altan Bonnet, senior research fellow at the National Institute of Cardiovascular and Hematology (NHLBI) Host-Pathogen Dynamics Laboratory, said: "This is an exciting discovery in the field of virology because It reveals a pattern of viral transmission that has never been observed in humans and animals. It hopes to provide clues to viral research involving multiple diseases, including gastrointestinal diseases, heart inflammation, respiratory diseases and even The type of virus common to the common cold."
In the past, most scientists believed that viruses, especially those that cause gastrointestinal diseases, can only be transmitted as individuals who are infected independently. However, the new study found that rotavirus and norovirus exist in the form of a virus-encapsulated virus in the feces. A membrane vesicle containing multiple viral particles is more infectious than a virus that is freely present in another set of samples. Researchers have compared this new pattern of viral transmission to "trojan horses" -- a computer virus, a group of virus-encapsulated viruses that reach and deposit in host cells while evading the immune system. Detection.
They believe that the high infection rate may be due to the fact that the vesicles transmit many viruses to the target tissue at one time, protecting the internal virus from being destroyed by prolonged exposure to the enzyme, and ensuring that the virus avoids contact with host excreta or antibodies in the intestine. Therefore, the ability of the virus to spread and spread is stronger, causing serious diseases. (éƒå朔)
