Better Control of TB Seen If a Faster Cure Is Found The World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis(结核病). Most times, the infection remains inactive(不活跃的). But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug - resistant forms of tuberculosis. Current treatments take at least six months. Patients have to take a combination of several antibiotic(抗生素)drugs daily. But many people stop as soon as they feel belter. Doing that can lead to an infection(传染病)that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others. The researchers developed a mathematical(数学的)model to examine the effects of a two -month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve. The World Health Organization developed the DOTS program in nineteen ninety. DOTS(短 期直接观察治疗)is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance for TB Drug Development(全球结核病药物开发联盟)says its long-term goal is a treatment that could work in as few as ten doses. The mathematical model tested in Southeast Asia shows that a faster cure is developed and in wide use as early as the year of______

Ebola Outbreak1 You are likely aware that several countries in West Africa are battling an Ebola outbreak. Ebola is a dangerous and often lethal viral infection. Scientists believe that humans contracted the virus by eating the meat of rare animals. It is now believed that bats are the primary carriers of the virus.2 To date, there are only three major countries in West Africa experiencing a major outbreak: Sierra Leone, Liberia and Guinea. However, other countries such as Nigeria have reported confirmed cases of Ebola with their border.3 Unless you recently visited one of the three affected West countries, your risk of contracting the virus is virtually zero. Unlike other recent airborne virus outbreaks like SARS, the Ebola virus can only be spread through direct contact with an infected person. Specifically, Ebola is spread through contact with body fluids. Though the vims is transmittable, only an infected person exhibiting symptoms is communicable.4 The signs and symptoms of Ebola are non-specific and patients typically exhibit them after a week of contracting the virus. Symptoms may appear as early as two days or as late as three weeks after initial infection. Symptoms include disgust, weakness and stomach pain. More uncommon symptoms include chest pain, bleeding and sore throat.5 Ebola is devastating because of its ability to attack and replicate in every organ of the body. This causes an overstimulation of the body’s inflammatory response, causing the flu-like symptoms. The virus also causes bleeding and impairs the body’s normal clotting mechanism(凝血机制), making bleeding even more severe. Loss of blood volume and decreased organ perfusion(器官灌注)ultimately lead to organ failure and death.6 The current outbreak is the deadliest viral outbreak in over 35 years. While diseases such as the malaria(疟疾)are far more communicable, Ebola is one of the world’s most fatal viral infections. Ebola’s fatality rate exceeds that of SARS.A Am I at risk of contracting the virusB Is the current outbreak the deadliestC How do I know if I have contracted the virusD What areas are currently affectedE What exactly does Ebola do to the bodyF What caused the Ebola outbreak Paragraph 5______
A infected body fluidsB against the outbreak severityC the mode of transmissionD the initial days of being infectedE three countries in West AfricaF within a wide range of days The Ebola virus transmits by contact with______.
