Pathophysiology: Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium responsible for several difficult-to-treat infections in humans. Healthy individuals may carry MRSA asymptomatically for periods ranging from a few weeks to many years. Patients with compromised immune systems are at a significantly greater risk of symptomatic secondary infection. Initial treatment of the infection is often based upon quick detecting and identifying MRSA strains.
Statistics: There was no geographical clustering of the 82 confirmed cases among the 4 districts in Hong Kong (Hong Kong Island 27%, Kowloon 28%, New Territories East 20% and New Territories West 26%). The average lag time from the date of symptoms onset to date of notification was 21 days.The 82 cases comprised 45 males and 37 females. Their ages ranged from 12 days to 93 years (median 32 years). 80% were adults aged between 20 and 59 years. About 15% (12 cases) were children under 18 years of age.
Treatment: Healthcare providers can treat many S. aureus skin infections by draining the abscess or boil and may not need to use antibiotics. Draining of skin boils or abscesses should only be done by a healthcare provider. For mild to moderate skin infections, incision and drainage by a healthcare provider is the first-line treatment.
Major Research: Some in vitro studies with honey have identified components in honey that kill MRSA. Ocean-dwelling living sponges produce compounds that may make MRSA more susceptible to antibiotics. Some semi-toxic fungi/mushrooms excrete broad spectrum antibiotics, not all of which have been fully identified; some have been shown to inhibit the growth of Staphylococcus aureus.
