Researchers estimate that the inci dence of Lyme disease in domestic animals may be sixfold to tenfold that found in humans. WILLIAM E. RYAN, D.V.M. FortDodge, Iowa The CDC officer drawing blood from a Guinea Bissau native is not wearing gloves (page 121), though the CDC has repeatedly emphasized in its publications that all patients should be assumed to be infectious for blood-borne pathogens. Imple menting this simple infection-control procedure is undoubtedly more difficult in the field. Neverthe less, a disposable syringe and butterfly needle were used to obtain the blood specimen. Wearing gloves would have been a good idea. BISHARA J. FREIJ, M.D. Royal Oak, Michigan I was struck by your coverage of AIDS. I am a vol unteer at a foster home for six children born with HIV antibodies. It is a common fallacy that chil dren born with these antibodies inevitably come down with AIDS. In actuality, by the time they reach 24 months and their mothers' antibodies have worn off, 50 to 70 percent show no signs of infection. We are very fortunate that all our chil dren are healthy and can lead full normal lives. MICHELLE J. PARLO Atlanta, Georgia Pumas Your map ignores the mounting evidence for the existence of the catamount, a native puma species, in Vermont. In the Northeast Kingdom and the Green Mountains, sightings and other evidence of a puma population continue to accumulate. EDWARD L. QUEVEDO Laguna Hills, California Although random sightings have been reported in Vermont, none have been confirmed by photo graphs,tracks, or carcasses.Officialssay there is no breedingpopulation.
