SARS SARS (atypical pneumonia): Severe acute respiratory syndrome that ravaged the whole world from the winter of 2002 to the spring of 2003. At the end of 2002, there were many cases of unexplained respiratory diseases in Guangdong, China. Subsequently, this symptom appeared all over the world, and who named it? Sars? All regions are devoted to finding the pathogen of this disease. Sars is excreted through respiratory secretions, spread through sneezing and contact, and is highly contagious.
Plague: Plague is a severe infectious disease caused by Yersinia pestis infection, and it is a class A infectious disease among the legal infectious diseases in China, ranking first among the legal infectious diseases. In nature, Yersinia pestis is mainly hosted by rodents, mainly spread by rats and fleas, and even spread to dogs, rabbits, sheep and other animals, and now spread to humans. The first Justinian plague, the second Black Death and the third plague have been plaguing the world. But there are also protective measures, one is to strictly control the source of infection, the other is to cut off the route of transmission, and the third is to protect susceptible people.
Ebola outbreak: Ebola virus, also known as Ebola virus, is a virulent infectious virus, which can cause Ebola hemorrhagic fever in humans with a very high mortality rate. The main causes of death are stroke, hypovolemic shock or multiple organ failure. Ebola virus is mainly transmitted through blood, body fluids and indirect contact, accompanied by hematemesis, liver and kidney failure or serious complications, and usually dies within 8.9 days of the course of the disease.
The epidemic is not terrible. As long as we unite as one, we will surely defeat it. Here I want to share some of my suggestions with you:
Wash your hands frequently, reduce going out and reduce the burden for the country.
Don't let your guard down, don't take risks.
Go retrograde with the epidemic and March towards dawn!
