The common cold probably causes more misery to more people than any other viral infection. Researchers have now found that it is possible to stop the spread of colds – at least within families.
Several recent studies have shown that alpha 2 interferon sprayed into the nose protects against colds, especially those caused by a class of viruses called rhinoviruses. Unfortunately, after a couple of weeks the treatment also causes many people’s noses to become dry, stuffy and bloody.
In a new clinical trial, researchers led by Robert Douglas at the University of Adelaide, and Frederick Hayden and his colleagues at the University of Virginia, found that spraying interferon into the nose once a day for a week could keep colds away in the short time, with only an occasional case of mild nasal bleeding.
Both groups of researchers tested the spray on the people most vulnerable to catching colds-those living with someone who had just come down with an infection. The Australian group found that only 14 percent of the interferon users showed cold symptoms. This result was confirmed by testing patients’ nose and throat swabs for the presence of virus. The American researchers found that only 7 percent of people treated with interferon fell ill during the trial period, but 35 percent of people using placebos became ill.
To find out how long the protection lasts, they assessed the incidence of colds in the two weeks following treatment. Only 1.3 percent of the people who used the drug developed colds that could be confirmed in laboratory. Fifteen percent of those on placebos succumbed.
