Saudi Arabia and Oman report new MERS infections
The Saudi Arabian Ministry of Health (MOH) announced a new case of MERS-CoV late last week, in a household contact of a previously reported case.
A 36-year-old Saudi woman from Jeddah was diagnosed as having MERS-CoV (Middle East respiratory syndrome coronavirus). She presented with symptoms and is in stable condition. Last week the MOH said a 56-year-old Saudi man from Jeddah had MERS-CoV after coming into contact with camels.
Saudi Arabia's MERS-CoV total cases since 2012 have now reached 1,816, including 736 deaths. Nine people are still being treated for their infections.
Meanwhile, the World Health Organization (WHO) on Mar 15 announced a new MERS-CoV case from Oman, that country's first of the year. The patient was 74-year-old Omani man, living in Batinah whose symptoms began on Feb 23. An investigation found that prior to his illness he had taken care of camels that were reportedly sick.

US and Europe warn of yellow fever threat in Brazil, urge vaccination
Both the US Centers for Disease Control and Prevention (CDC) and the European Centre for Disease Prevention and Control (ECDC) issued warnings late last week for travelers heading to Brazil.
Brazil is currently experiencing its largest yellow fever outbreak in decades, with an upsurge of cases recorded since January.
The CDC said Friday during media briefing that all travelers to Brazil should receive a yellow fever vaccination at least 10 days prior to their trip. If they are unable get the vaccine, the CDC said they should avoid traveling to areas of Brazil where vaccination is recommended.
The CDC said travelers who were vaccinated more than 10 years ago for yellow fever may consider getting a booster dose before their trip, and it warned that the vaccine is available at a limited number of clinics that that travelers should plan ahead to get the vaccine.
The ECDC released a similar warning, highlighting recent cases of yellow fever among unvaccinated Europeans.
"Five travel-associated cases of yellow fever have been reported among unvaccinated EU/EEA travellers returning from Brazil, since the beginning of January 2018," the ECDC said. "In Switzerland an unvaccinated traveler infected with yellow fever died. For comparison, there were six travel-related cases in EU/EEA travelers between 1999 and 2016."

Kratom-related Salmonella outbreak sickens 47 more, spreads to 35 states
A multistate Salmonella outbreak linked to kratom supplements has sickened 47 more people and expanded to 8 more states, raising the total to 87 cases from 35 states, the US Centers for Disease Control and Prevention (CDC) said in a Mar 15 update. States reporting their first cases are Alaska, Illinois, Indiana, Maryland, Mississippi, Nevada, Texas, and West Virginia.
Also, three other Salmonella subtypes have been linked to the outbreak: Salmonella Javiana, Okatie, and Thompson. Patients included in earlier reports were infected with S I 4,,12:b:-. The latest illness onset is Feb 24, and patient ages range from 6 to 67 years. So far 27 people have been hospitalized, but no deaths have been reported.
State and local health officials continue to interview sick people about foods they ate and other exposures. Of 55 people interviewed so far, 40 (73%) reported consuming kratom in pills, powder, or tea. Kratom is used as a stimulant and herbal alternative to opioids and is also known as Thang, Kakuam, Thom, Ketom, and Biak.
Investigators in three more states have found outbreak strains in leftover and unopened kratom products. California officials found the S I 4,,12:b:- outbreak strain in leftover Phytoexactum brand kratom power from a patient in that state, which on Mar 10 prompted a recall of PXD Aromatics kratom powder sold online between Jan 18 and Feb 18 of this year.
Also, authorities in Oregon and Utah who tested kratom powder from retail outlets and online sellers where sick people bought kratom identified Salmonella Okatie and Salmonella Thompson in the samples. No brand was available for the kratom sample from Oregon, but the Utah sample was sourced from the website kratoma.com.
In an earlier update, the CDC said health departments in North Dakota and Utah had identified the outbreak strain in kratom samples. Despite the spate of positive samples, the CDC said no single common brand or supplier has been connected to the outbreak. For now, it recommends that the public avoid any brand of kratom in any form.

Afghanistan notes more WPV1 cases; DRC has 2 vaccine-derived polio cases
Afghanistan has reported two more wild poliovirus 1 (WPV1) cases, and the Democratic Republic of the Congo (DRC) has reported two more cases of vaccine-derived poliovirus type 2 (cVDPV2) in its ongoing outbreak, the Global Polio Eradication Initiative (GPEI) said in a Mar 16 update.
The cases in Afghanistan are advance notifications, and more details will be available in later updates, the GPEI said. However, it noted the new WPV1 cases are from Kunar and Kandahar provinces. So far this year, Afghanistan has reported five WPV1 cases.
Three positive WPV1 environmental samples have been detected in Afghanistan, all from Nangarhar province, and another has been reported in Pakistan's Balochistan province, according to the GPEI.
In the DRC, the two new cVDPV2 cases are from two provinces, Haut Lomami and Tanganyika. Paralysis onsets were Jan 16 and Jan 19, respectively. They reflect the first cases of 2018, after 22 cases reported so far for 2017. The DRC's government recently declared a public health emergency due to the ongoing cVDPV2 outbreak.
