Will I get the disease??? If you are infected, you will not get sick?

In China, HIV infection is divided into acute phase, asymptomatic phase and AIDS phase.

a) Acute phase: usually occurs about 2-4 weeks after the initial HIV infection. The main clinical manifestations are fever, sore throat, night sweats, nausea, vomiting, diarrhea, rash, arthralgia, lymphadenopathy and neurological symptoms.

Most patients have mild clinical symptoms that last 1 to 3 weeks and then resolve.

At this stage, HIV RNA and p24 antigens are detected in the blood, while HIV antibodies do not appear until several weeks after infection. The CD4+ T lymphocyte count is transiently reduced, and the CD4 to CD8 ratio can be inverted.

2) Asymptomatic period.

It can be entered from the acute phase, or it can be entered directly without obvious acute symptoms.

This period generally lasts 6-8 years. But there are also those who progress rapidly and those who do not progress for a long time. The length of this period is related to various factors such as the number and type of infected virus, the route of infection, and the immune status of the body.

3) AIDS period.

It is the final stage of HIV infection. The patient's CD4+ T lymphocyte count decreased significantly, with a < of more than 200 mm3, and the HIV plasma viral load was significantly increased. The main clinical manifestations in this stage are HIV-related symptoms, various opportunistic infections, and tumors.

HIV-related symptoms: fever, night sweats, diarrhea lasting more than one month; Weight loss of more than 10%. Some patients present with neuropsychiatric symptoms such as memory loss, apathy, personality changes, headaches, epilepsy and dementia.

Persistent generalized lymphadenopathy may also be present, characterized byswollen lymph nodes in two or more locations other than the groin; ②.lymph nodes 1 cm in diameter, non-tender, non-adhesional; Duration more than 3 months.

Common symptoms of HIV-related risk infection** tumors: fever, night sweats, swollen lymph nodes, cough and sputum hemoptysis, dyspnea, headache, vomiting, abdominal pain and diarrhea, gastrointestinal bleeding, dysphagia, decreased appetite, oral leukoplakia and ulcers, various skin rashes, vision loss, blindness, dementia, epilepsy, limb paralysis, weight loss, anemia, fecal incontinence, urinary retention, intestinal obstruction, etc.

You can go to the hospital for a temporary blood test, but the result is not 100% accurate, because the incubation period of AIDS is relatively long, and it is recommended to stay away from high-risk sexual behaviors.

In this case, only a screening test can be done.

Li Tong once introduced that there are indeed some infectious diseases that will not be easily obtained once, such as measles, rubella, mumps, hepatitis A, etc., the reason is related to the characteristics of these pathogenic microorganisms.

Although in the end, many people are difficult to avoid being infected, but I still hope that everyone "late infection, dust core as much as possible not to infect", especially "do not take the initiative to infect", after a long time after the infection, the antibody titer in the body will be lower and lower, when it is no longer enough to resist the invasion of the virus, there is a possibility of secondary infection, if the virus mutates, there may be immune escape, the risk of secondary infection will be even greater.

Compared with Delta and previous variants, Omicron is more likely to cause reinfection, and in addition, repeated infection still has a certain risk of severe disease, which will be transmitted to high-risk groups such as the elderly at home and people with underlying diseases.

1. What kind of diseases are contagious?

Infectious disease refers to a disease that is transmitted directly or indirectly from a pathogen to a healthy person, causing the healthy person to become ill. These pathogens may be microorganisms such as bacteria, viruses, fungi, parasites, etc., or animals with snakes, bats, etc. as hosts. The main transmission routes of infectious diseases are airborne transmission, droplet transmission, direct contact, and blood transmission.

2. Which diseases are pure infectious diseases

Some well-known infectious diseases include tuberculosis, AIDS, influenza, pneumonia, measles, chickenpox, infectious mononucleosis, etc. These diseases are transmitted by different routes, such as influenza and measles, which are transmitted by droplets; Tuberculosis, pneumonia, etc. are transmitted through the air; AIDS is mainly transmitted through blood.

3. Measures to prevent infectious diseases

Important measures to prevent communicable diseases include personal protection, environmental hygiene and vaccination. Personal protection includes frequent hand washing, use of masks, and avoiding crowded; Scientific diet, strengthening exercise, and enhancing physical fitness are also important preventive measures. Environmental sanitation is mainly to keep indoor and outdoor clean and ventilated, eliminate hazardous waste, etc.

For some common infectious diseases, such as measles, tuberculosis, etc., corresponding vaccines can be given, which can help reduce the incidence rate.

4. How to deal with patients with infectious diseases

Patients with infectious diseases should be diagnosed and treated in a timely manner, and personal protection should be strengthened during the ** period. During isolation**, you should stay in a designated place and take your medication as prescribed. Families and family members should give adequate attention and help, and should also follow protective measures such as isolation and disinfection.

If there are symptoms of suspected infectious diseases, you should go to the hospital in time to receive relevant examinations and**.

When suffering from a viral infection, the first thing that comes to everyone's mind is **. At the same time, I am worried about whether my disease will be transmitted to others. Because many viruses are contagious at some point, will they be contagious when they are infected?

Viral infectious diseases mainly refer to infectious diseases that can parasitize and multiply in the human body and can cause diseases. The main manifestation is that the patient will have symptoms of systemic poisoning such as fever, general malaise, and headache after viral infection. Viral infections in the human body are mainly divided into recessive viral infections, overt viral infections and chronic viral infections.

When infected with the virus, it will infect people, and the virus may be transmitted through the respiratory tract or digestive tract or **, placenta, reproductive tract or blood. Therefore, when you are infected with the virus, the first thing is to avoid being too close to others to prevent yourself from infecting others. In the face of patients infected with the virus, you should also stay away to avoid being infected.

Whether it is contagious or not is unpredictable. But I feel that the country takes coronavirus pneumonia so seriously. And now that science and technology are so advanced, and medicine is so advanced, I think that corresponding drugs will be developed in the near future. The crisis will soon be resolved.

Yes. Right now. Online. Say. There's a lot of this.
