The recommendations for the treatment of gonorrhea have been changed: ceftriaxone 500 mg IM plus azithromycin 1 g PO is recommended. Prophylaxis of recurrent cellulitis with penicillin 250 mg 2 x/d PO may be considered. E. coli ESBL does not require contact isolation anymore. Fecal transplantation seems so far to be the most effective treatment of recurrent C. dificile. Two new respiratory viruses, Middle East Coronavirus (MERS-CoV) and avian-origin Influenza A (H7N9) have been reported. Oral valganciclovir treatment reduces the risk of hearing loss in congenital CMV infection. An outbreak of mould infections of the central nervous system has been described in the United States following injection of contaminated steroids.
