The Coalition against Typhoid is proud to announce that Dr. Samir Saha, the chair of our steering committee, is the distinguished recipient of the American Society of Microbiology’s 2017 Award for Research in Clinical Microbiology. This award recognizes a clinical microbiologist for outstanding lifetime achievements that have led to or formed the foundation for important applications in clinical microbiology. Dr. Saha is the first researcher based in a low-income country to win this prestigious award. We at the Coalition against Typhoid are honored to have Dr. Saha on our steering committee helping to guide our strategy, outreach and activities.

  • New Findings for Typhoid Fever in Africa – The results of the Typhoid Surveillance in Africa Project, a first-of-its-kind study, shed light on the true burden of typhoid and multi-drug resistance in Africa
  • From Evidence to Action: Typhoid Experts Exchange Data, Strategies During Biannual Conference – More than 300 researchers from 45 countries gathered in Kampala, Uganda in early April for the 10th International Conference on Typhoid and Other Invasive Salmonelloses. Hosted by the Sabin Vaccine Institute’s Coalition against Typhoid, the three-day conference – the world’s only such meeting devoted to the diseases – centered on the theme “From Evidence to Action” as attendees reviewed crucial developments to reduce the global burden of these diseases

Typhoid Watch

  • Fiji – The increasing incidence of typhoid cases in Nalawa, Fiji is largely due to the drinking of grog mixed with contaminated water
  • Malaysia – The Health Ministry has issued 309 injunctions against food outlet operators who failed to ensure that their food handlers received typhoid vaccines
  • New Zealand – The March/April typhoid outbreak in Auckland, New Zealand has spread to Palmerston North, infecting two children
  • Philippines – A father and his daughter have died four days apart from each other after falling ill with typhoid fever. A four-year-old boy from the same family and two other patients are still in the hospital
  • Syria – A typhoid crisis is threatening to overwhelm the city of al-Bab, still reeling from recent conflict between the Free Syrian Army and the Islamic State. Dozens of residents are daily contracting typhoid fever from wells contaminated with raw sewage
  • Tonga – A total of 17 typhoid cases have been recorded to date in Tonga, the majority of which are women and children

  • Zimbabwe – A humanitarian situation report from the UN Children’s Fund found that Zimbabwe has seen more than 2,200 suspected typhoid cases since the beginning of the year

Antimicrobial Resistance

  • Kenya – Typhoid researcher Sam Kariuki warns that H58, a deadly typhoid strain circulating widely in East Africa, is now resistant to 60 percent of locally available antibiotics
  • India – Widespread use of over-the-counter antibiotics are increasing drug resistance in typhoid, making the disease harder to treat
  • World Health Organization – Antimicrobial resistance is a global health challenge on the rise in every region of the world, and an epidemic of multidrug-resistant typhoid has been rolling across parts of Africa and Asia
