The rise of drug-resistant virulent strains of S. aureus has led to increasing concern in the medical community. Although sick patients with compromised immune systems and children are most susceptible to the strains, helathy persons have also been infected. Pharmaceutical companies are working to develop new antibiotics to kill drug- resistant strains.
