請依下文回答第 26 題至第 30 題：  Extending health coverage to illegal immigrants is sound policy. The inclusion of theillegal-immigrant population may lower costs in numerous ways, including lower insurance premiums,lower emergency medical expenditures, and a switch from expensive late-stage treatments tocost-effective preventative and ambulatory care. Coverage will obviously benefit illegal immigrants, butthe entire US population will also reap the rewards of a broader risk pool comprising individuals withcomparatively low medical expenditures and usage trends. Extending coverage could also haveimportant public health benefits. Ensuring treatment, especially of infectious disease, protects the healthof the population as a whole, and this is particularly important considering the ease of travel and accessto different parts of the globe. The public health is also served by prompt diagnosis and treatment ofchronic diseases, such as heart disease and diabetes. Allowing illegal immigrants to stay and pretending they’re not here doesn’t work for anyone.Prohibiting inclusion of illegal immigrants in the formal healthcare system and at the same timeextending piecemeal benefits, emergency rooms, and some patchwork of state and local governments isa poor way to address the intractable problem of ever increasing health care costs. The federalgovernment should meet this challenge head-on in the form of health coverage, recognizing the benefitsthat could accrue to it by instituting necessary health insurance reforms. Even if immigration reformdoes materialize, nothing will have been lost by providing coverage in the interim. As the illegalimmigrant population declines, for instance, because of fewer economic opportunities in the UnitedStates or absorption into the lawful immigrant category, the system has enough fluidity to respond.Further tweaks may be necessary, but incremental improvement is a characteristic of any publicbenefits scheme. What is not acceptable is to tacitly ignore the problem while setting up additionalbarriers to coverage.
