How long can HIV survive? At present, AIDS can not be completely cured. AIDS is a viral infectious disease, which has a fatal impact on people's health. Let me introduce how long the HIV virus will survive. Welcome to read!

How long can HIV survive? 1 HIV is very weak in vitro, divorced from the human body, and its survival time is short, so it will not be infected with AIDS in daily life.

At room temperature, HIV in liquid environment can survive 15 days, and articles contaminated by HIV are contagious for at least 3 days.

In recent years, some research institutions have confirmed that the survival time of HIV virus in isolated blood depends on the virus content in isolated blood, and blood with high virus content can still survive even if it is stored at room temperature for 96 hours.

Even a drop of blood, if it meets fresh lymphocytes, HIV can still replicate and spread. Blood with low virus content will lose its vitality after natural drying for 2 hours; Even if the blood with high virus content is dried for 2-4 hours, once it encounters lymphocytes, it can still enter the culture medium to continue to imitate.

HIV can't survive without blood and body fluids.

Although HIV is highly contagious, it is also very weak. They can only live in living cells in blood and body fluids, but not in air, water and food. Without these blood and body fluids, these viruses will soon die.

Air itself can't kill HIV, but contact with air will make body fluids dull, and then many viruses will be quickly destroyed.

The US Centers for Disease Control and Prevention said that a few hours of suffocation can reduce the activity of the virus by 90-99%, and it can only spread when the blood or body fluids of the infected person directly enter from one body to another.

Can survive for several days in an injection needle.

In the blood left by used needles, HIV can survive for several days. Because the blood stays in the needle, it is not easy to get tired. The use of needles can directly enter human blood, so used needles are very dangerous for HIV infection.

The ideal solution is that used needles should not be reused. If it is to be reused, it must be treated with bleaching powder or alcohol before use.

The chance of getting infected with HIV due to handling body fluids is extremely small, because these body fluids have little chance to enter human blood. However, when handling blood, semen and secretions, anyone should pay attention to prevent them from contacting damaged skin or mucosa (such as around eyes).

Any behavior that leads to body fluid communication may spread HIV. There are three ways of transmission of HIV: sexual contact transmission, blood transmission and mother-to-child transmission.

How long can HIV survive? What are the early symptoms of AIDS?

1, headache.

Headache is a very obvious symptom of AIDS. About14 AIDS patients have different degrees of headache or migraine.

2, fever.

Fever is an obvious symptom of AIDS. Fever may be caused by HIV, or it may be caused by other organ infections caused by AIDS infection. At the same time, there will be problems such as fatigue and lymph node enlargement.

3, sore throat.

Sore throat is a common occurrence among AIDS patients. It seems to be a cold-like swelling and pain, and thrush may also appear. This is a fungal infection, but it is also a timely candida infection. When the human immune system has problems, fungal infection becomes a very easy situation.

4, rash.

About 90% of AIDS patients have had rashes. After the rash appears, many red spots will appear on my body and I feel itchy. These rashes mainly occur on the face, feet, hands or chest.

5, oral ulcers.

Most AIDS patients will have oral ulcers at an early stage. Oral ulcer will haunt the patient's body for a long time, which will greatly affect eating and taking medicine. If you are a person with frequent oral ulcers and risky behavior, you'd better have a check-up.

In addition to the above symptoms, AIDS patients may also have joint pain, night sweats, diarrhea and other symptoms. These symptoms are complicated and need to be treated in time.

How long can HIV survive? 3 What is AIDS?

The medical name of AIDS is "Acquired Immunodeficiency Syndrome" (AIDS for short).

Aids is caused by HIV, which is called "human immunodeficiency virus" (HIV for short) in medicine.

After HIV invades the human body, it will constantly replicate in the body, gradually destroying the immune function of the human body, reducing the ability of the human body to resist diseases, prone to various infections and tumors, and eventually leading to death.

AIDS prevention knowledge

1, don't take drugs, * * * People who inject drugs with syringes are prone to HIV infection.

2. Avoid unsafe injection or blood transfusion to prevent AIDS from spreading through blood, so don't inject for diseases that can be treated by taking medicine, and don't transfuse for diseases that can be treated by injection to avoid unnecessary blood transfusion.

3. Go to a regular hospital for medical treatment, don't trust street advertisements, and don't go to an individual clinic without a medical license for injections, infusions, tooth fillings, etc.

4. When seeking medical treatment, you should choose to use disposable needles and strictly sterilized medical devices.

5. Don't go to an informal beauty and plastic surgery institution to do skin puncture surgery such as eyebrow tattoo, tattoo, ear piercing and deformity correction.

6. Don't use toothbrushes, razors and other daily necessities that may puncture the skin.

7. Donate blood at a regular blood station designated by the state. Free blood donation is not only conducive to ensuring the safety of clinical blood use, but also will not affect the health of blood donors.

8. When helping others to stop bleeding, protect yourself, avoid touching blood and wounds with bare hands, use clean handkerchiefs, paper towels or latex gloves for first aid, and then go to the hospital.

Under what circumstances is AIDS not contagious?

HIV is a very fragile virus, and it will die soon after leaving the human body.

1. The virus content in saliva, tears, sweat and urine is too low to spread. At present, no cases of AIDS infection through these body fluids have been found.

2, with HIV infected people and patients in daily life and general contact will not be infected with AIDS. Such as: shaking hands, hugging, courtesy kissing (kissing on the cheek), eating together, riding a bike, studying, outing, playing, using school utensils, dining utensils, toilets, swimming pools, bedding and daily necessities.

3. HIV will not spread through droplets, and coughing or sneezing will not spread AIDS.

Mosquito bites will not spread AIDS. HIV will not develop or replicate in mosquitoes, and the blood left by mosquitoes is very small, which is far from enough to cause infection. At present, there are no reports of HIV infection due to mosquito bites.
