Many With Dog Allergies Might Only Be Allergic to Male Dogs
Getting a female dog or neutering your male dog may help ease your dog allergies, an expert says.
"Up to 30% of people who are allergic to dogs are actually allergic to one specific protein that's made in the prostate of a dog," Dr. Lakiea Wright, an allergist at Brigham and Women's Hospital in Boston, told CNN.
"If you're allergic to only that specific protein in the male dog, you may be able to tolerate a female or a neutered dog," Wright said.
A blood test for the allergen was approved last May by the U.S. Food and Drug Administration, CNN reported.
American Embassy in China Issues Health Alert Over Mystery Illness
A mysterious pneumonia outbreak in China has prompted the U.S. embassy there to warn Americans traveling in the country to avoid contact with sick people and animals.
Since the viral illness was first reported last week in the central Chinese city of Wuhan, the number of cases has increased to at least 59, CBS News reported.
"Be aware and practice usual precautions," said the health alert issued Tuesday by the U.S. embassy. It advised Americans to seek medical care "right away" if they felt ill after being in Wuhan.
Fears have spread online that the highly contagious SARS virus -- which caused hundreds of deaths more than a decade ago -- has returned, but the Chinese have ruled that out, CBS News reported.
