Oman reports 4 new MERS infections, Saudi Arabia 1

Several Arabic media outlets are reporting that the Omani ministry of health has confirmed 4 more MERS cases in Oman, while Saudi Arabia also noted a new, fatal case.

The Omani cases are part of an ongoing outbreak and bring the total to 10 recent cases of MERS-CoV (Middle East respiratory syndrome coronavirus) in that country, which had not seen the a MERS case since March 2018.

According to Avian Flu Diary, an infectious disease tracking blog, the Omani ministry of health said the 10 cases have resulted in 4 deaths in different provinces. If confirmed, that would mean the outbreak is no longer contained to a single family farm, as reported by the World Health Organization on Feb 11.

The Saudi Arabian Ministry of Health (MOH), meanwhile, today recorded another new MERS-CoV case for epidemiologic week 7 in Wadi ad-Dawasir.

The infection lifts the country's MERS-CoV cases since the first of the year to 61, which includes 38 from Wadi ad-Dawasir, the site of a possible hospital-based outbreak.

The patient is a 60-year-old man who died after acquiring MERS in a healthcare setting. He did not have camel contact, a known risk factor, the Saudi MOH said.

Study: 1 to 4 meningitis B outbreaks on US college campuses annually

According to a study yesterday in Emerging Infectious Diseases, from 2013 to 2017 officials confirmed one to four meningococcal serogroup B outbreaks on American college campuses annually, which suggests that wider use of the MenB vaccine could be used in outbreak and non-outbreak settings.

Since 2005, most American college students have been vaccinated with the quadrivalent meningococcal conjugate vaccine covering serogroups A, C, W, and Y (MenACWY), but serotype B has now become the most prevalent on college campuses. In 2013, MenB became available for outbreak response, and, by 2015, MenB vaccines were available for wider use, though not routinely administered.

From January 2013 to May 2018, there were 10 university-based meningococcal disease outbreaks caused by serogroup B reported in seven states, which resulted in 39 cases and 2 deaths (5% case-fatality rate).

"Only 1 case occurred in a student who previously received MenB vaccine; this student had been vaccinated with 1 dose of MenB vaccine 6 days before disease onset," the study authors, from the Centers for Disease Control and Prevention, said. "The remaining cases occurred in persons believed to be unvaccinated with MenB vaccine."

In all but two outbreaks, mass vaccination campaigns with MenB were put in place across campus, and the vaccine was also offered at campus health centers, by appointment, and during seasonal flu vaccinations. Still, MenB vaccination coverage in response to university-based outbreaks was highly variable, ranging from an estimated 14% to 98% for the first dose (median, 67%), the study authors said.

"Coverage with >1 dose of MenB vaccine among persons 17 years of age was estimated to be 14.5% in 2017 (13), and a recent survey demonstrated that only 2% of universities require MenB vaccination for student," the authors concluded. "Achieving high MenB vaccination coverage is necessary to help protect persons during outbreaks of meningococcal disease caused by serogroup B."
