Don't worry about daily contact.
At the beginning of the AIDS epidemic, people doubted whether it could spread through air, food and daily life, and some places also caused a certain degree of panic, so there appeared discrimination phenomena such as prohibiting AIDS children from going to school and unwilling to work, study and live with AIDS patients and their families. The influence of these initial misunderstandings is still difficult to eliminate today. In fact, there is absolutely no need to worry about AIDS in daily life contact.
People are worried about infection through drinking water and food, including eating together and using unsterilized tableware, mainly because saliva has the function of spreading HIV. In fact, in all the data in the world, no case of HIV infection due to kissing has been found. Recently, when studying saliva, American scientists found that there is a kind of protein in saliva, which can effectively inhibit HIV infection of human immune cells in test tubes. It is said that this protective effect can last up to 4 weeks. This discovery can explain why oral contact such as kissing and eating together will not spread AIDS.
In addition, studies in various countries have now found that the resistance of HIV to the external environment is very weak, and even if it is exposed to the air, it will soon die. Unlike the spread of influenza, whooping cough and other infectious diseases, it cannot be spread through the air, that is, it cannot be infected through the respiratory tract. Therefore, attending classes in the same class and working in a workshop or office with AIDS patients will not be threatened by infection.
Similarly, AIDS cannot be transmitted through daily contact, including skin contact such as shaking hands and touching, and even swimming with infected people, using toilets and tubs, touching clothes, bedding, money and other instruments used by patients. Even in the family of AIDS patients, other members will not be infected if they are not breast-fed or have no sexual contact with each other. The United States investigated18,000 families of AIDS patients, and no one was infected except the sexual partner of the infected person. Therefore, it is not dangerous to communicate with AIDS patients in general, travel around the country, and even take care of AIDS-infected people and patients, as long as they abide by the general health protection rules.
In fact, the adaptability of HIV to the outside world is quite weak, and its tolerance to various physical and chemical factors is not as good as that of hepatitis B virus. Therefore, all physical and chemical factors used to inactivate hepatitis B virus can inactivate HIV, and even washing with tap water and residual chlorine in water can kill HIV.
So, tell your friend firmly that he will not be infected! ! !
