When a human victim of viral infection gets a stuffy head and a sore throat, or suffers a splitting headache and the feeling that his bones are breaking, or develops the blisters of cold sores or the rash of measles, his body is reacting to the biochemical disturbances that come from invasion by viruses. Viruses kill millions of people around the world every year, and give the miseries to hundreds of millions more...
...drugs cannot affect true viruses. The effect is to leave the virus diseases supreme, and virologists are multiplying with a speed reminiscent of the particles they study. Having only in the last dozen years dug out the mechanics of viral cell invasion, researchers now know of fascinating variations in the process. Occasionally and inexplicably; they have learned, viral nucleic-acid particles enter cells and "go underground," lying there dormant or masked for years. Or the nascent "pro-virus" molecules of new nucleic acid may play possum in this way. Virologists are having to coin words such as virion, capsid...
...record of failure. Last week, concluding a series of three articles in the A.M.A. Journal, a group of Navy doctors reported on an antibiotic that works well against what seems to be a form of virus disease. The antibiotic is Declomycin, a close relative to aureomycin. The disease is viral pneumonia...
Bacterial pneumonia, once a major killer, is now largely controlled by sulfa drugs and antibiotics. Viral pneumonia is another matter. Believed to be caused by many kinds of viruses, and called primary atypical pneumonia (PAP) by doctors, the disease presents an uncomfortable array of symptoms. The patient usually does not get suddenly ill; he gradually gets coldlike symptoms, distressing headaches, rising temperature, chills, and a severe cough. The sickness may last weeks, though it rarely kills...
Other virologists, mindful that liver inflammation may be caused by many agents, hopefully awaited further evidence that their colleagues had indeed found viral culprits in a disease that now ranks as one of the U.S.'s most serious infectious-disease problems...
