1, AIDS
AIDS is a very harmful infectious disease, which is caused by HIV infection. HIV is a virus that can attack the human immune system. It takes CD4T lymphocytes, the most important cells in human immune system, as its main target, and destroys them in large quantities, making human body lose its immune function.
Therefore, the human body is susceptible to various diseases, malignant tumors can occur, and the mortality rate is very high. The average incubation period of HIV in human body is 8 ~ 9 years. During the incubation period of HIV, you can live and work for many years without any symptoms.
2. Symptoms
It takes several years, even 10 or even longer, for an HIV infected person to develop into an AIDS patient. Due to the extreme decline of the body's resistance, there will be many infections, such as herpes zoster caused by special pathogenic microorganisms, oral mold infection, tuberculosis, enteritis, pneumonia, encephalitis, and serious infections caused by many pathogens such as Candida and Pneumocystis.
Malignant tumors often occur in the late stage, and long-term consumption leads to systemic failure and death.
Step 3: Countermeasures
Although many medical researchers around the world have made great efforts, so far, no specific drugs have been developed to eradicate AIDS, and there is no effective preventive vaccine. AIDS has been listed as a Class B legal infectious disease in China, and it is one of the infectious diseases monitored by frontier health.
