谁知道艾滋的起源与发展(英文)
AIDS,the medical all called "acquired immunodeficiency syndrome" (Acquired Immune Deficiency Syndrome - AIDS),the human body is infected with human immunodeficiency virus (HIV),also called the AIDS virus caused by infectious diseases.What is worth mentioning is that HIV itself does not cause any disease,but when the immune system damaged by HIV,the human resistance due to lose their ability to infect other diseases leading to death!閫氫織鍦拌?,AIDS is the body's immune system to be HIV destruction,the threat to human lives and loss of ability to resist pathogens,which in a variety of infections or tumors,eventually led to the death of a serious infectious disease.Transmission of the virus for life,the destruction of the immune system,making the body lose the ability to resist various diseases.When infected with HIV and the immune function of the severely damaged by the virus,and even unable to maintain a minimum capacity of resistance when infected people will develop AIDS patients.With Human Immunodeficiency lower,people will more and more frequently infected with various pathogenic microorganisms,and the extent of infection will become more and more serious,and there will be for various composite infection leading to death.AIDS mainly through blood,improper sexual behavior,drug use and mother-to-child transmission of genetic four.International medical profession does not have any effective against AIDS drugs and treatments.Therefore,AIDS,also known as "Super cancer" and "the killer."
HIV acronym HIV is a human immune system to attack the virus.The body's immune system it the most important T4 lymphocytes as a target of attack,a large number phagocytosis,destruction T4 lymphocytes,thereby undermining the immune system,and finally to the collapse of the immune system so that the exposure to loss on the ability to resist various diseases and the incidence and death.Scientists to this virus called "human immunodeficiency virus." AIDS virus in the human body the incubation period averaged 12-13.In the past developed into AIDS patients look normal,they may have no symptoms to live and work for many years.
AIDS stands for the English transliteration of the word AIDS,have translated it as "AIDS","love disease." 1981 in the United States first discovered and confirmed.After the virus entered the human immune function that is lost,vulnerable to other diseases and death.General through sexual contact,blood transfusions and intravenous means of transmission.Known as "20th century plague."
HIV and AIDS difference between HIV (AIDS virus),on behalf of mankind Immunizations HIV.A person infected with HIV,the virus began to attack this human Immunizations system,the human Immunizations system is a function of defeat disease.After several years,HIV weakened Immunizations system,this time,the body becomes infected with the opportunity of STIs,such as pneumonia,meningitis,tuberculosis.Once opportunistic infections occur,this person was considered to be suffering from AIDS.AIDS (AIDS),on behalf of acquired Immunizations defect syndrome.AIDS is not a disease in itself,but could not resist a state or other diseases - like syndrome.People do not die of AIDS,but will die from AIDS-related diseases.
HIV-infected people and AIDS distinction
HIV infection is already infected with the AIDS virus,but also showed no obvious clinical symptoms were not diagnosed as AIDS; AIDS patients refer to the already infected with the AIDS virus,and there have been obvious clinical symptoms,been diagnosed with AIDS.The similarities between the two are carrying the AIDS virus,is contagious.The difference is AIDS patients to have appeared obvious clinical symptoms,and infected with HIV has not yet appeared obvious clinical symptoms,with the appearance looks healthy person.This period is called latency,latency period for asymptomatic infection,in addition to the current HIV-positive,without subjective symptoms and positive signs.Latency vary in length and six months to 12 years,a small number could reach 20 above.AIDS virus in the human body the incubation period averaged six years.
AIDS on the origin and development of the origin of AIDS have many legends,it was said to be Germany during the Second World War,the artificial study by a virus; It was also said to be out of the Japanese research; was also said to be God to punish humanity the chaos of the disagreements befall mankind.And so on and so on the argument,the majority is no real basis.For the development of human understanding of the history of AIDS,in fact it is very essential for one thing,to human AIDS prevention and tackled.In fact,the origin of AIDS should be in Africa.In 1959 the Congo,or the French people's land value.Since going out in a forest of the natives,and to be invited to participate in a blood disease related research.He tested blood samples,was to be frozen,this dust-laden for decades.涓囨病鎯冲埌that,several decades later,blood samples AIDS has become a source of untied important clues.
AIDS originated in Africa and then by the immigrants into the United States.On June 5,1981,the United States Centers for Disease Control in Atlanta,"Morbidity and Mortality Weekly Report," a brief introduction of the five cases of AIDS patient's history,this is the world's first official record on AIDS.In 1982,the disease was called "AIDS." Soon after,the rapid spread of AIDS to all continents.In 1985,a foreign tourist to China Youth Beijing Union Medical College Hospital for sick soon after the death,was certified died of AIDS.This is the first discovery of AIDS in China.
AIDS is a serious threat to the survival of mankind,has caused the World Health Organization and governments are highly valued.AIDS spread in the world's rapidly growing,a serious threat to human health and social development,has become a threat to people's health and the fourth largest killer.UNAIDS May 30,2006 declared that since June 1981 the first confirmed AIDS has 25 wholly-for a total of 65 million people infected with HIV,of which 2.5 million people died.By the end of 2005,the global total of 38.6 million infected with HIV,then the additional infected with HIV and 4.1 million people,and another 2.8 million people died of AIDS.In November 2006 the United Nations UNAIDS and the World Health Organization (WHO) in Geneva jointly issued in 2006 AIDS global epidemic of the latest situation.The report shows that the global AIDS epidemic still growing trend:At present,there are 39.5 million people infected with the AIDS virus than in 2004 increased by 2.6 million people,including 15 children under the age of the number of infections to 2.3 million.In 2006 the global total of 2.9 million people died of AIDS,including 15 children under the age of deaths for 380,000; the same year also added 4.3 million infected people,of which 65% (about 2.8 million people) appeared in sub-Saharan Africa.Calls upon all Governments to prevent the spread of AIDS be adequate attention to prevent the situation from deteriorating further.According to experts,AIDS-infected persons from the time of initial infection,after several years or even as long as 10 years or longer incubation period before developing into AIDS patients.AIDS patients because of extreme resistance in a variety of infections will decrease,such as herpes zoster,oral fungal infection,tuberculosis,caused by pathogenic microorganisms special enteritis,pneumonia,encephalitis,and so on,often in the latter part of malignancy until because of a prolonged consumption,systemic failure deaths.
Although many medical researchers around the world has made great efforts,but has not yet developed a cure AIDS drug effects,nor can be used for the prevention of an effective vaccine.At present,this fatality rate almost as high as 100 percent "super cancer" has been included in the Group B statutory communicable diseases in China,and was listed as one of frontier health monitoring infectious diseases.So we called "super ill."
AIDS Clinical 3 1.HIV infection.Patients infected with HIV have no clinical symptoms after only in the blood of HIV antibody test results are positive;
2.AIDS-related syndrome.Patients in inguinal lymph nodes outside the two above-mentioned reasons unknown lymphadenopathy and lasted more than three months,while a systemic symptoms like fever,fatigue,loss of appetite,weight loss and diarrhea;
3.AIDS stage.Patients outstanding performance pathogenic infections,and the occurrence of malignant tumors could not find the reasons for the cellular immune defects.
