2 1 century, how many diseases have been confirmed by the World Health Organization on a global scale?

Marburg virus, named after Marburg, a city in West Germany, is also called green monkey disease virus, green monkey factor, Marburg virus and so on. It is a deadly virus and the source of Marburg hemorrhagic fever.

Marburg virus is related to Ebola virus and originated from Uganda and Kenya in Africa. It is a common disease of human beings and other primates. The virus was transmitted from animals to humans, but the source of the virus is still unknown.

From June 5438 to October 2004, Marburg virus broke out in Angola, Africa, and it didn't subside until July 2005, killing more than 300 people.

According to the figures of the US Centers for Disease Control and Prevention, the number of cases increased by 3% every day in 2005. The morbidity and mortality of this epidemic is still as high as 10%, and it is as high as 20% in the first five months.

2. Ebola virus.

Ebola virus has also been translated into Ebola virus. Is a very rare virus,

1976 found its existence in the Ebola River area in southern Sudan and Congo (DRC) (formerly Zaire), which aroused widespread concern and attention in the medical field, hence the name "Ebola".

The biosafety level of Ebola virus is level 4 (AIDS is level 3, SARS is level 3, and the higher the level, the stricter the protection). The incubation period of the virus can reach 2 to 2 1 day, but usually it is only 5 to 10 day.

20 16, 16 On February 23rd, the World Health Organization announced that the vaccine developed by the Public Health Bureau of Canada can effectively resist the Ebola virus.

3. rabies.

Rabies is an acute infectious disease caused by rabies virus, which is zoonotic, mostly carnivores such as dogs, wolves and cats. Most people are infected by bites from sick animals.

The clinical manifestations are peculiar fear of water, wind, pharyngeal muscle spasm and progressive paralysis. Gu Bing's disease is also called water phobia because of its prominent symptoms.

Rabies virus belongs to rabies virus genus of Rhabdoviridae, which is a single-stranded RNA virus. Animals spread the virus by biting each other.

4. HIV.

Human immunodeficiency virus, also known as HIV, is a retrovirus that causes defects in the human immune system.

This virus will attack and gradually destroy the human immune system, leaving the host unprotected when infected.

People who die of human immunodeficiency virus often die of secondary infection or cancer. And AIDS is the last stage of human immunodeficiency virus infection.

5. novel coronavirus

Tan Desai said that this is the first epidemic caused by coronavirus in the world and the first epidemic that can be controlled by human beings.

Previously, the World Health Organization insisted on using the word epidemic and avoided using this description to prevent more panic around the world.

On June 5438+1October 3 1, WHO listed the epidemic situation of new coronary pneumonia as a "public health emergency of international concern" (PHEIC), and on February 28, the global risk level of the epidemic situation was raised from "high" to "very high".

The epidemic situation in COVID-19 has escalated to "epidemic situation"-four global pandemics in history.

The evolution of COVID-19 into a "global epidemic" not only means the escalation of the severity of the epidemic, but also means the escalation of the difficulty in fighting the epidemic.

Our goal is to create a better and healthier future for people all over the world.

WHO has six regions and 65,438+094 member countries. Its employees work in more than 65,438+050 offices, and * * * is committed to improving the health of everyone in the world.

We work together to prevent and treat diseases, including infectious diseases such as new coronary pneumonia and HIV, as well as non-communicable diseases such as cancer and heart disease.

We help mothers and children survive and develop so that they can look forward to a healthy old age. We ensure that people breathe safe air, eat safe food, drink safe water and use safe drugs and vaccines.
