A drug-resistant strain of scarlet fever, resistant to macrolide antibiotics such as erythromycin, but retaining drug-sensitivity to beta-lactam antibiotics, such as penicillin, emerged in Hong Kong in 2011, accounting for at least two deaths in that city—the first such in over a decade.[1] About 60% of circulating strains of the group A streptococcus that cause scarlet fever in Hong Kong are resistant to macrolide antibiotics, according to Professor Yuen Kwok-yung, head of Hong Kong University's microbiology department. Previously, observed resistance rates had been 10–30%; the increase is likely the result of overuse of macrolide antibiotics in recent years.[citation needed]
