据美国《纽约时报》近日报道，一种由吸血昆虫引发的致命疾病正在美洲大陆蔓延，因为感染者在患病初期与艾滋病患者的症状类似，有专家把它称为美洲国家面临的“新型艾滋病”威胁。
这种疾病其实名叫查加斯病，是一种由单细胞寄生虫造成、由昆虫叮咬传播的热带疾病。被感染后，患者会出现心脏和食道组织发炎，约四分之一的患者会出现心脏或肠道过度肥大，进而引起心跳骤停或猝死。
根据美国科学公共图书馆PLoS近日发表的一篇文章，美国贝勒医学院的热带病专家称，这种疾病目前在美洲的爆发形态十分类似于早期艾滋病的传播，因此也查加斯病也被叫作了“新型艾滋病”。
同艾滋病一样，查加斯病可通过血液或母婴传播，而且通常具有一个很长的潜伏期。除非患者发现得早，并经过3个月的大剂量药物治疗，否则基本不可能治愈。
目前美洲大陆已有约800万人感染上了这种“新型艾滋病”，大部分分布在墨西哥、中美、玻利维亚和哥伦比亚。其中美国的感染人数已经达到30万。
而据泛美卫生组织称，查加斯病是一种“穷人的疾病”，在贫穷区域发病率较高。由于危害大、感染人数多以及难以预防等特点，美国疾病预防控制中心已经将其列为五大被忽视的寄生虫感染疾病之一。
The outbreak of American States called Chagas disease "new AIDS", the U.S. has 30 million infected, a higher prevalence of poor regions.
According to the United States, "New York Times recently reported, fatal disease caused by blood-sucking insects are the American continent spread of infected persons is similar to the prevalence of early AIDS symptoms, some experts call it American countries face the" new AIDS threat.
In fact, the disease called Chagas disease, is caused by a single-celled parasite, a tropical disease spread by insect bites. After infection, the patient will appear to the heart and esophagus tissue inflammation, about a quarter of patients with heart or intestinal hypertrophy, thereby causing cardiac arrest or sudden death.
According to an article recently published by the U.S. Public Library of Science PLoS, Baylor College of Medicine in Tropical Diseases (TDR) experts said the disease outbreak form in the Americas is very similar to the early spread of AIDS and, therefore, Chagas disease also called made a "new AIDS".
AIDS, Chagas disease can be spread through blood or maternal and child, and usually has a long incubation period. Unless the patient is found early, and large doses of medication after three months, otherwise basically impossible to cure.
The American continent about 800 million people are infected with this "new AIDS", the majority of distribution in Mexico, Central America, Bolivia and Colombia. The number of infections in the United States has reached 300 000.
According to PAHO Chagas disease is a "poor man's disease, a higher prevalence in the poorest regions. Due to the large number of infections is more difficult to prevent harm, the U.S. Center for Disease Control and Prevention has listed it as one of the five neglected parasitic infection diseases.
