Among the unnumbered Americans who suffered last week from sniffles and fevers caused by a variety of viruses, tens of thousands had influenza. The outbreaks skipped across the map from Florida to Missouri and Illinois, over the Continental Divide to the southwestern mountain states, and up the Pacific Coast to remote island villages in Alaska...
...lungs so that pneumonia develops. In an already weakened patient, this may prove incurable. In plotting flu's ravages, PHS tallies all "excess deaths" (above normal for the city and season) in 108 U.S. cities, and checks to see whether the peaks coincide with a rash of "influenza-pneumonia" entries on death certificates. So far, throughout the U.S.. there have been few reports of such "excess deaths...
...cover. Among those he chose to use, the sticklike viruses at upper left are the tobacco mosaic virus, which figured importantly in early virological discoveries made in the 19th century; the smaller, pellet-shaped viruses at the upper right are polio; the four at the lower right are influenza...
...Influenza viruses were found to have horns or spikes. On some of these is an enzyme that can dissolve part of a cell's outer coating. Presumably, this is what the flu virus uses to open a hole in the cell-factory wall for its nucleic-acid core to slip through. A virus known as T2 bacteriophage (it attacks bacteria) was found to have a tadpole shape; the "tail" is like a coiled spring around a tiny hypodermic needle that stabs the cell wall, and through this the nucleic-acid core is injected. Micrographs show whether viruses are basically...
...Influenza. Various virus subtypes cause the disease, so need is for a general-purpose vaccine. Lederle Laboratories' civilian vaccine combats four strains, including Asian. Manufacturers say Public Health Service delayed too long in warning of probable outbreaks this fall and winter, so output has fallen behind need. Demand is high; black markets might develop. Made from viruses grown in incubating eggs and killed with formaldehyde, flu vaccine gives only moderate, far-from-permanent immunity. No major improvement in prospect. Russia, despite setbacks, is trying to perfect an influenza vaccine that can be inhaled or swallowed...
