新型 肺炎 生物 兵器 - ロシア医学アカデミーの医学者が、新型肺炎（SARS）のウイルスは（おそらく生物兵器開発の過程で）創り出された、と発言

Chinese experts are carrying out experiments on animals to verify the conclusion, Hong claimed. They have been found in samples from some patients with the deadly respiratory virus, but until now there has been no evidence they are widespread in people with SARS. All have direct or indirect links to the SARS outbreak in Hong Kong and Guangdong province, China," the researchers said in their report released early by the journal. But authorities in the United States and other countries believe they have the infection under control. He does not exclude that the spread of the virus could have begun accidentally, as a result of "an unsanctioned leakage" from a laboratory. He also said that in creating bacteriological weapons a protective anti-viral vaccine is, as a rule, worked out at the same time. Only four of 60 patients who needed hospitalization were still admitted Wednesday. A top epidemiologist was quoted by media reports as saying today that seven new cases of Sars has been detected in Southern Guangdong Province. Centers for Disease Control and Prevention CDC in Atlanta also said the same day that the virus suspected of causing SARS is a new type. SARS, which was spread around the world by travelers, has killed an estimated 110 people and infected more than 3,000. A CDC publication released yesterday said nine people in the United States believed to have the illness got it through household contact with an infected person, while three of the U. The Army Medical Research Institute of Infectious Diseases laboratory in Frederick, where Jahrling is the top virologist, was in its first week of screening drugs against the virus. A second article in the New England Journal of Medicine, published by another team of international researchers, suggested naming the virus Urbani SARS-associated coronavirus, after Dr Carolo Urbani. Carlo Urbani during the investigation of the initial SARS epidemic, we propose that the virus be named Urbani SARS-associated coronavirus," they wrote. The drug interferon is next on the list. The lung damage seen in patients who died of SARS looks more like the damage done by measles, respiratory syncytial virus and some other diseases, and not like the damage done by other coronaviruses, they said. The theory about sewage emerged when the virus appeared to spread from floor to floor to more than 250 people in the Amoy Gardens apartment building in Hong Kong. The laboratory also plans to test that drug and up to 2,000 others against virus isolated from three SARS patients in Canada, he said. The finding lends support to a previously advanced theory that the virus might spread via cockroaches that have had contact with sewage, said Dr. The latest Centers for Disease Control and Prevention statistics reflect this. The new coronavirus, a relative of one of the many viruses that cause the common cold, is, as suspected, new to humans, two research teams reported in the New England Journal of Medicine. Major symptoms shared by SARS patients included high fever, muscle pain and a dry cough. If it's in sewage, then you need to worry about how it's handled. Severe acute respiratory syndrome, or SARS, is so much milder in the United States than abroad that Florida epidemiologist Steven Wiersma says some experts cautiously joke about renaming the U. This can be done only in a laboratory, the academician is convinced. Only one person has needed mechanical assistance breathing, and no one has died, says Julie Gerberding, director of the CDC. But they trigger severe illnesses in animals. After conducting case studies, Chinese scientists have 'strong evidence' to prove that it is a great possibility that Severe Acute Respiratory Syndrome SARS patients are attacked by a Chlamydia agent or a corolla-virus-like agent, or even co-infected by the two, the chief expert of the Institute for Viral Disease Control and Prevention, Hong Tao said. Health authorities are baffled at the apparent difference in the severity of a disease caused by the same virus in different countries. It brings the number of cases in the province to 1,220 and the number countrywide to 1,297. But Gerberding said yesterday that health officials are investigating to determine whether the virus may have spread for the first time in a workplace in the United States. In Florida, health investigators discovered a co-worker of a suspected SARS patient who had a respiratory illness and also placed that person on the list of suspected SARS cases. But just in case, she said the CDC will post new guidance regarding SARS patients for schools and the workplace. It is likely that the virus mutated and was passed from animals to humans, becoming more virulent and spreading rapidly, the CDC said. Gerberding, the CDC's director, said it was still too early to draw a final conclusion about the cause of severe acute respiratory syndrome. Canada, in contrast, reports 253 suspected cases and 10 deaths. The CDC, World Health Organization and doctors in affected areas, eager to find the root of the mystery disease, tested for the usual suspects, such as influenza and other known bacterial and viral causes of pneumonia, which turned out negative. Nearly all got sick after traveling in Asian countries where most of the cases have occurred. Finding genetic evidence of the virus in stool samples is not the same as saying the virus was present in them, she told reporters yesterday on a conference call. It is possible the damage is caused by the body's immune response. Larry Anderson and colleagues tested samples from patients in six countries with SARS. All had serious respiratory illness which was not obvious without X-rays. Some patients must be put on respirators to help their lungs function. But Jahrling said the lab already had concluded that ribavirin, an anti-viral some doctors have been prescribing to people with SARS, doesn't work - at least not against the strain of coronavirus the lab has been using. But she added, "While we've seen evidence of the virus and we've seen evidence of pneumonia, we haven't seen them both in the same tissue. Professor Peiris claimed the Chinese University group had tested patients from fewer "clusters" of linked cases. The finding means that doctors can now concentrate on developing a simple test for the virus that will tell them right away whether a patient has Severe Acute Respiratory Syndrome, or SARS. When the immune system attacks a bacterial or viral infection, it sometimes kills healthy cells along with the microbes. Forty-five of the 50 people, aged from 23 to 74, had the coronavirus, but none of the control group. No one they have tested who does not have SARS has antibodies to the virus, suggesting it is new and that no one has been exposed to it before. The CDC team is working to sequence the DNA of the virus, which will give a better idea of what it is and where it originates. Genetic characterization indicated the virus is only distantly related to known coronaviruses," said the article written by researchers from institutes such as Germany's Benhard Nocht Institute for Tropical Medicine and France's Pasteur Institute. Therefore, the scientist believes, a medicine for atypical pneumonia may soon appear. Meanwhile, Beijing municipal authorities have stepped up efforts to prevent Sars from spreading in the sprawling city of over 12 million people with city officials pledging to offer free medical treatment to Sars patients who could not afford the expenses. In less than two months the team, led by professors Malik Peiris and K. The Chinese capital Beijing has reported 22 cases with four deaths. Another, he says, is that the broad definition, coupled with efforts to educate travelers who may have been exposed to SARS abroad, may prompt people to get treatment earlier than elsewhere. Christian Drosten of the Bernhard Nocht Institute for Tropical Medicine in Hamburg and colleagues across Germany, France and the Netherlands also pointed to coronavirus. The CDC said it has found the almost the same genetic characterization in 12 samples obtained from different locations, including China, Vietnam and Canada. The Hong Kong research was considered so significant the prestigious medical journal The Lancet published it online late Tuesday night and has made it freely available at www. About four percent of patients with SARS die. All of the patients with severe SARS had the virus, while none of the healthy people had it. Carlo Urbani, the World Health Organization doctor who died of SARS last month after treating one of the first patients infected with the virus in Vietnam. Of 166 people with suspected SARS in the USA, most have had normal chest X-rays. In China, Hong Kong and Singapore, areas hardest hit by the virus, the picture is less clear. Hundreds have developed pneumonia, and people in need of mechanical ventilation have filled intensive-care units in Hong Kong and Hanoi. The US Centers for Disease Control and Prevention, or CDC, has three such tests but says they are not suitable for everyday use. While international groups of scientists led by the federal Centers for Disease Control and Prevention in Atlanta and the Bernhard Nocht Institute for Tropical Medicine in Hamburg, Germany, linked the disease to the coronavirus, Julie L. Coronaviruses cause common colds and occasionally pneumonia in people. At Hong Kong's Chinese University, however, researchers have not found a high incidence of the coronavirus among its SARS patients. But it does not look like anything they have seen before in animals or people. The virus has a very different genetic make up from known coronaviruses, according to an article published in the leading medical journal. Army virologist whose Fort Detrick laboratory is working to find drugs that might be effective against the infection. SARS is marked by a high fever, dry cough and other flu-like symptoms but it progresses to pneumonia. It is thought primarily to be spread when infected people cough tiny droplets containing the virus into the air. In the laboratory, the virus grows freely in cells that don't contain interferon, leading Jahrling to say, "We have good reason to think interferon might work. It is possible that the virus, called a paramyxovirus, or other microbes may help make patients more ill or make them more likely to transmit SARS, Anderson's team said. Only 33 have developed pneumonia or respiratory distress. Worldwide, 111 of the 2,781 SARS victims have died. People who are quarantined will be monitored with Web cameras and an electronic wristband that sounds an alarm if they leave home. Australia's first possible case of SARS, a British tourist, was yesterday cleared of having the disease. One of two groups of scientists whose findings were published online yesterday in separate New England Journal of Medicine articles also said they had found genetic evidence of the virus in some victims' stool samples. Official statistics show that China has reported 55 Sars-related deaths and 1,290 cases. As of yesterday, SARS was suspected of sickening 166 people in 30 U. In contrast, his team investigated 50 patients from five clusters - using chest X-rays and blood and molecular tests - and compared the results to a control group of people without SARS symptoms. They tested samples from 18 SARS patients in Hanoi and 21 healthy people who had been in contact with the patients. RIA Novosti correspondent Alexander Batalin The virus of atypical pneumonia SARS has been created artificially, possibly as a bacteriological weapon, believes Sergei Kolesnikov, Academician of the Russian Academy of Medical Sciences. As SARS spread to a second Hong Kong housing block yesterday, infecting 30 people, Beijing officials were condemned by their own health staff for releasing false SARS statistics. Of those with suspected SARS, the virus could be found in 23 percent. In one of the studies reported on Thursday, the CDC's Dr. Urbani, an Italian doctor with the World Health Organization who first identified the SARS outbreak, died late March in a Bangkok hospital from the deadly illness. Yuen of Hong Kong University, also nailed down key symptoms and produced new guidelines on treating the deadly respiratory disease which has hit 2671 people worldwide and killed 103. Other viruses, like human-metapneumovirus, may still act as "opportunistic secondary invaders" which worsen the symptoms of SARS, the Hong Kong team reported. According to Dr Dwyer, the new evidence will speed up the development of fast and accurate diagnostic tests, proven treatments and vaccines for Severe Acute Respiratory Syndrome.。
