What kind of development has occurred in the detection technology and therapeutic drugs of the virus at this stage? 1 Photo Credit: TNL/ Zhu Jiayi Professor Wu Hongyi from the Institute of Veterinary Pathobiology, Zhongxing University, specializes in molecular virology and viral pathogenesis. Anti-epidemic characteristics and difficulties of viruses The biggest feature of viruses is that they have to live in cells to survive. Therefore, if it stays in the outside environment for a period of time (varies according to different viruses and environmental humidity and temperature, usually ranging from several hours to several days), it cannot continue to survive.
However, there are many ways of transmission of the virus, including Photo Manipulation Service droplet transmission (such as the 2019 novel coronavirus that caused Wuhan pneumonia), air transmission (such as foot-and-mouth disease virus), blood transmission (such as HIV, hepatitis B and C viruses), insects Transmission (such as Japanese encephalitis virus, Zika virus and dengue fever virus transmitted by mosquitoes) and so on. Widespread routes of transmission, coupled with the small particles of the virus itself, will cause difficulties in epidemic prevention.

But when compared to ordinary viruses, bacteria are nothing short of skyscrapers. (In order from left to right in the picture: bacteria, two giant viruses - jar virus and mimetic virus, T4 bacteriophage, HIV, Zika virus and parvovirus) In the case of coronaviruses, most of the members that originally infect humans only cause mild colds. However, the other three - SARS virus (SARS-CoV) causing severe acute respiratory syndrome, MERS virus (MERS-CoV) causing Middle East respiratory syndrome, and 2019 novel coronavirus disease (2019-nCoV) causing Wuhan pneumonia, Because it is an emerging virus, and everyone has no antibodies, it has caused varying degrees of damage in different regions during the outbreak.
