A needle can accommodate more than 300 million EV71 virus, hand, foot and mouth disease this year in Asia, fast. Singapore hand, foot and mouth disease with over 1 million people; As of May 6, China had 26 children died from the disease, most of which the deceased lived in Fuyang, Anhui region; Vietnamese Ministry of Health reported that May 6 this year, Vietnam The hand, foot and mouth disease has already reached about 2,000 people, more than in previous years.
Strange common diseases, hand, foot and mouth disease is not terrible. While many people are familiar with it, but the hand, foot and mouth disease in fact like a common cold, it is a common disease. It is caused by intestinal viruses. Enterovirus of the family is very large, many members. Their proliferation in human intestines and discharged from the gut. One of the most notorious is the polio virus that causes polio culprit.
In 1300 BC, Egyptian relief carvings, they provided information on the earliest record of polio – the young worship of a leg shrunk. Enteroviruses include Coxsackie virus, echovirus, and new enteroviruses. In accordance with serotype classification, these viruses have been followed by the current sort number to 71. Because the back of 72-type virus has been classified as hepatitis A virus, a virologist, so the family lineage of enteroviruses in 71 is terminated. In 1957, Canadian doctor first reported HFMD. Hand, Foot and mouth disease main threat to children. Children with normal first corner of the mouth pain, throat pain, and then hands, feet and mouth red spots. This spot does not look like mosquito bites after the left, more like chicken pox. Chickenpox was centripetal distribution, with head, face, chest, back the main, and then spread to the limbs. The hand, foot and mouth disease spots mainly in the hands, feet and mouth on. But also deteriorate into a small sore spot. After the puncture, which would be slightly out of muddy liquid, which can cause hand, foot and mouth disease containing the culprit – intestinal virus. In 1958, Canada, Dr. Luo Binsen from hand, foot and mouth disease isolated from stool CoxAl6, the Coxsackie virus type A16. It is found that the first human hand, foot and mouth disease can lead to intestinal virus. In 1969, California’s physicians are a 9-month-old children with encephalitis was first isolated from the faeces of a new type of intestinal viruses, intestinal virus, the virus is the youngest – intestinal virus, 71 (EV71). It is this virus, resulting in several deaths of children in Fuyang. EV71 belongs to Picornavirus intestinal virus, is divided into A, B, C three kinds of genotypes. EV71 is extremely tiny. The medieval philosopher who eagerly discussed a needle, and in the end how many angels can stand on the dance together. If we put this issue in the “angel” was changed to EV71, the answer would be a needle can accommodate more than 300 million EV71. EV71 is not even life. This is not another non-single-cell organism multicellular organisms, there is for the sole purpose of self-replication, and then infection of other cells. Under normal circumstances, EV71 other hand, foot and mouth disease caused only a mild infectious disease, 7 to 10 days will be cured, it will not left complication. However, this common disease but with the flu, like many around the world stirring up trouble.
EV71 “crime” survey, from a historical point of view, people EV71 other hand, foot and mouth disease caused by lack of understanding, often become non-malignant diseases such crimes against humanity reasons. EV71 was first found in the United States, after Australia and Sweden have also cropped up EV71 epidemic. The mid-20th century, 70, Bulgaria, Hungary, EV71 epidemic appeared one after another, only Bulgaria has more than 750 cases the disease, 149 were caused by paralysis, 44 people were killed. Other countries such as Italy, France, the Netherlands, Spain, Romania, Brazil, Canada, Germany, frequently caused by the EV71 HFMD. Asia, Japan is more hand, foot and mouth disease country’s history there have been several large-scale epidemic. In 1973 and 1978, two hand, foot and mouth disease epidemic caused by EV71, from 1997 to 2000, EV71 has been active again in Japan. After a long-term follow-up study, scientists found that EV71 in the A-type virus spread more than in California, while the B-and C-type in the Far East or even widely disseminated around the world. In other words, EV71 is not a country, “patent”, it has “globalization” feature. Present except Antarctica, the other continents have been reports of EV71 epidemic. The 20th century, the late 90’s, EV71 epidemic in Asia, the region expanded. Have taken place in Malaysia in 1997 caused mainly by EV71 hand, foot and mouth disease epidemic, a few months there are 29 patients died, mostly less than 2-year-old children. In March 1998 to December, EV71 large-scale epidemic in China’s Taiwan region, the official report found that patients with hand, foot and mouth nearly 13 million, whereas the private sector have estimated that the actual number could be more than 1 million children. At the time of the 405 severe cases, nearly 20% of the children died under the age of five children all died of severe. The analysis shows that after the SARS attack on the lack of understanding of the disease delayed treatment, is the leading cause of death in children. Mostly children, died in a high fever 2 to 4 days afterwards taken to a hospital, general hospital but was pronounced dead less than 24 hours. The autopsy found that, EV71 virus has invaded the brain in children. China’s Hong Kong in 1987 occurred in EV71 epidemic in 2001, the first deaths occurred. In the Mainland, the first a hand, foot and mouth cases have occurred in 1981, Shanghai, Wuhan Institute of Virology in 1995, in the EV71 virus, isolated from the mainland for the first time. Although the hand, foot and mouth disease in the Mainland to visit has been for nearly 30 years, but the people for the understanding of hand, foot and mouth disease is still a blank, and Taiwan that year will be similar. Large number of people even confuse the hand, foot and mouth disease and foot and mouth disease. Hand, Foot and mouth disease and foot and mouth disease has been confused why the main part is sick with the similarities, both of which occurred in the mouth, fingers and toes end. But in either case not just one issue. Pathogens of foot and mouth disease foot and mouth disease virus, belonging to zoonotic pathogens, generally only the first appears OIE be possible to make people sick. Hand, Foot and mouth disease is caused by intestinal infection, its mode of transmission is contact with the patient, through the daily supplies, utensils, toys, contamination by oral infection can also be transmitted through the respiratory tract. Virus on humanity’s greatest threat comes from the malignant variant. But the WHO’s China representative in Beijing, Han Zhuo liters at a press conference that mainland China At present, all cases of hand, foot and mouth disease virus is found in the same subtype, there is no evidence that the virus has evolved into a more lethal type of , or it may have different sources.
Against known viruses, most people will first think of the vaccine. However, EV71 is still no effective vaccine, it can only deal with the virus from the human experience of the most fundamental starting point, cut the popular three components: source of infection, transmission and susceptible populations. Hand, Foot and mouth disease is already the main source of infection in patients with this disease. The onset of 1 ~ 2 weeks after discharge in patients with pharyngeal still virus, 3 to 5 weeks, the stool also may still be discharged virus, herpes virus, contains large amounts of fluid even more. Therefore, disease prevention and control is to isolate the sick first and foremost, to enable patients to rest at home, reducing out. At the same time the patients have been contaminated with daily disinfection of feces and other waste be thrown into the bleach soak. EV71 of the main mode of transmission is through close contact among people. To prevent this sector, the key is doing a good job environment, food and personal hygiene, washing hands before meals and after done. Hand, Foot and mouth disease in susceptible populations are mainly pre-school children, particularly within the 3-year-old age group the highest incidence rates. The Ministry of Health of the newly released “Hand, Foot and Mouth Disease Control and Prevention Guide” (2008 version), it was stressed that “good children, individuals, families and nurseries in health is the key to prevention of infection in this disease.”
In order to prevent harm to babies exposed to this disease, parents should be minimized so that their children to crowded public places, having fun, children’s nutrition should also be attention to rest, to avoid sunlight exposure and prevent fatigue. Do not let children drink unboiled water and eating cold food, avoid contact with sick children. Contact with children before, change diapers, have to wash their hands after handling feces and properly handle the dirt; infants and young children to use baby bottles, pacifiers should be fully cleaned before and after use; room and often ventilation, ground drying clothing. Children, high fever subsided, or if there speech retardation brain symptoms, should be immediately sent to hospital for treatment. For symptoms of minor children who, without hospitalization, appropriate home treatment, in order to reduce cross-infection. Now take the following measures to alleviate the disease: taking anti-viral drugs, such as ribavirin, viruses, Ling, etc.; maintaining local clean to avoid secondary bacterial infections; if there is erosion of oral, pediatric eating difficulties, can give flow digestible food, mouthwash after meals; part can be coated aureomycin, cod liver oil in order to alleviate pain and promote healing of erosive surface at an early date; also oral B vitamins, such as vitamin B2 and so on.
Hand, Foot and mouth disease and influenza-like epidemic season, the current hand, foot and mouth disease epidemic in China could not come to its peak. Han Zhuo-sheng, that the onset of hand, foot and mouth disease virus were often peaked Liu Qiyue Thus, China’s epidemic situation in earlier than usual, which means that as the weather continued warming of cases likely to increase. Treatment of this disease, should maintain a rational attitude, there is no need to irrational panic. Hand, Foot and Mouth Disease in China’s development also proves this point. In March of this year, China’s mortality rate of hand, foot and mouth disease, once as high as 11%, but in the second half of April, the death rate has fallen to 0.2%.
In the next period of time my hand, foot and mouth disease may continue to increase. However, with the state emergency operations, medical diagnosis and treatment of disease, increasingly accurate, self-protection awareness of the people increased, the impact of the disease on children will continue to decrease. For the people of the world concerned about the Olympic Games in Beijing, Han Zhuo l said, “I think this (hand, foot and mouth disease) to the Olympics or any major event is imminent is not a threat.”
