The presence of moisture in the ear for prolonged periods of time is probably the biggestrisk factor for an otitis externa infection. Indulging in activities that cause heavy perspiration, water trapped in the ears from swimming or bathing and extremely humid weather conditions can allsignificantly increase the risk of infection. Many people tend to be careless with ear care and in an effort to keep the ears clean use objects like hairpins that are not meant for the purpose. Even the...
