Saudi Arabia reports 3 new MERS cases, 1 fatal
Saudi Arabia's Ministry of Health (MOH) today reported three new MERS-CoV cases in separate cities, one of which was fatal.
The newly reported fatality involved a 73-year-old Saudi man in Riyadh. Potential exposure to MERS-CoV (Middle East respiratory syndrome coronavirus) in a healthcare setting is under investigation. He had no recent contact with animals or with MERS cases in the community.
The second patient is a 30-year-old male expatriate in Unayzah, which lies northwest of Riyadh in Al-Qassim region. He is in critical condition. He reported no recent contact with another MERS patient, but possible animal contact is being investigated.
The third patient is a 44-year-old male expatriate in Shaqra, a town midway between Unayzah and Riyadh in Riyadh region. He had recent camel exposure but no contact with other MERS patients.
None of the three patients was a healthcare worker (HCW) or had preexisting disease.
The MOH also reported the recoveries of two expatriates in Riyadh, a 50-year-old male HCW and a 76-year-old woman. A 34-year-old male expatriate HCW in Buraydah also recovered from MERS-CoV, the MOH said.
The country has now confirmed 936 MERS cases, including 402 deaths. It noted that 507 patients have recovered, while 27 are still receiving treatment.

University of Oregon infections trigger meningitis B campaign
A type B meningococcal disease outbreak at the University of Oregon that sickened four freshmen, one of them fatally, since the middle of January has prompted a mass vaccination campaign with the vaccine against the subtype, according to an update yesterday from the Oregon Health Authority (OHA).
The fatality occurred on Feb 17, and the Lane County Health Department has been identifying contacts to assess who should receive antibiotic prophylaxis.
The 4-day vaccination campaign started on Mar 2, targeting all undergraduates at the University of Oregon, Eugene, campus, graduate students who live on campus, and any students with certain high-risk medical conditions. Last week the university said more than 3,000 students had already been vaccinated.
For the campus campaign, students are receiving Trumenba, made by Wyeth, which targets Neisseria meningitides serogroup B. Trumenba is given in three doses, with the second 2 months later and the final dose 6 months later. The school will hold follow-up vaccination clinics in May and September.
As part of the campaign, the US Centers for Disease Control and Prevention (CDC) and the OHA will be asking students to voluntarily provide throat swabs as a measure to look for asymptomatic carriage.
The Oregon outbreak is the second to occur at a US college this year. In February officials at Providence College, based in Providence, R.I., said meningitis B infections hospitalized two students since Feb 1, triggering a vaccination campaign that began on Feb 8.
The Food and Drug Administration (FDA) recently approved two type B meningococcal vaccines, Trumenba in October and Bexsero, a Novartis product, on Jan 23. Approvals for both vaccines had been fast-tracked, because type B has become the most prevalent of the serogroups that can cause meningococcal disease in the United States. Federal officials cleared Bexsero for emergency use in two college outbreaks in 2013, one at Princeton University and the other at the University of California, Santa Barbara.
On Feb 26 the Advisory Committee on Immunization Practices (ACIP) of the CDC voted unanimously to recommend the type B vaccine to high-risk groups, such as those with low immunity and college students in outbreak settings.

Two more hospitals report scope-related 'superbug' infections
A second Los Angeles hospital and one in Hartford, Conn., reported drug-resistant "superbug" infections linked to contaminated duodenoscopes, Reuters reported yesterday.
Cedars-Sinai Medical Center in Los Angeles reported four infections with carbapenem-resistant Enterobacteriaceae (CRE) and said 67 more patients were at risk. Two weeks ago the UCLA Ronald Reagan Medical Center in Los Angeles reported seven CRE infections, two of them fatal, linked to the fiber-optic instrument.
A hospital in Hartford, meanwhile, reported at least five duodenoscope-linked infections involving drug-resistant Escherichia coli. A Hartford Courant story yesterday identified the hospital as Hartford Hospital and said officials were notifying 281 additional patients of possible exposure.
Rocco Orlando III, MD, chief medical officer of Hartford HealthCare, said that the endoscopies that led to potential exposures in the past several months are of a type reserved for very ill patients and were not general endoscopies, the Courant reported.
The FDA, meanwhile, updated its alert on the type of duodenoscopes involved in the outbreak.
