Brief instructions for the diagnostic of specimens coming from suspected plague cases and exposed contacts, including recommendations for diagnostic confirmation
The technical note from the Global Task Force on Cholera Control (GTFCC) examines the risks and benefits of vaccinating pregnant women with WHO-prequalified oral cholera vaccines (OCVs) during mass vaccination campaigns. It highlights that three WHO-approved vaccines (Dukoral®, Shanchol™, and Euv
...
ichol®) offer sustained protection and a strong safety profile.
While these vaccines are not explicitly contraindicated for pregnant women, there is limited clinical data on their use during pregnancy. However, studies indicate that pregnant women with cholera face higher risks of fetal loss, stillbirth, and complications, especially if they experience severe dehydration. Some evidence suggests that vaccination can reduce cholera incidence in pregnant women and indirectly protect infants.
Although no controlled trials have focused on pregnant women, retrospective studies in Guinea and Zanzibar showed no significant increase in adverse pregnancy outcomes after OCV administration. The GTFCC concludes that the benefits of vaccination outweigh the risks, particularly in high-risk areas, and recommends including pregnant women in cholera vaccination campaigns while continuing to monitor safety data.

The technical note by the Global Task Force on Cholera Control (GTFCC) discusses the use of Oral Cholera Vaccines (OCVs) for international workers and travelers in cholera-affected areas. It reviews the effectiveness of WHO-prequalified vaccines (Dukoral®, Shanchol™, and Euvichol®), emphasizing
...
their role in preventing infection and reducing transmission risks.
The document highlights concerns about travelers contracting cholera in endemic regions and potentially spreading the disease upon returning home. While the overall risk is considered low, certain groups, such as humanitarian workers and travelers to high-risk areas like South Asia, face a higher exposure.
Recommendations include vaccination for emergency and relief workers who may come into direct contact with cholera patients or contaminated environments. However, routine vaccination for general travelers is not widely recommended. The note also calls for better surveillance and studies to assess the potential of vaccines in preventing international transmission.

The Interim Guidance on Cholera Rapid Diagnostic Tests (RDTs) by the Global Task Force on Cholera Control (GTFCC) provides recommendations for using RDTs to detect cholera in areas with limited laboratory capacity. It highlights the advantages of RDTs, such as rapid detection (within 30 minutes), ea
...
se of use by non-laboratory personnel, and their role in early outbreak identification and surveillance. However, it emphasizes that RDTs should not replace culture or PCR testing, as they vary in sensitivity (58-100%) and specificity (60-100%). The document advises on proper test selection, storage, training, and integration into national surveillance systems to enhance cholera response efforts.

The objective of this guidance document is to support the public health professionals
in implementing effective surveillance of cholera in at-risk, endemic and epidemic
areas. This document has been developed by the Surveillance Working Group of the
Global Task Force for Cholera Control (GTFCC) a
...
t the World Health Organization based
on the existing documents, guidelines, tools and articles related to surveillance of
cholera disease, as well as technical discussions with experts held during GTFCC
meetings.

The GTFCC Laboratory Support for Public Health Surveillance document provides guidelines on using DNA-based molecular techniques for identifying and monitoring Vibrio cholerae strains in cholera outbreaks. It highlights the importance of genetic sequencing for tracking transmission, detecting new va
...
riants, and improving outbreak response. The report explains methods like PCR testing, whole genome sequencing (WGS), and multiple loci VNTR analysis (MLVA), detailing their advantages and applications. It also outlines best practices for sample collection, storage, and transportation, emphasizing collaboration between national and international laboratories to enhance cholera surveillance and control efforts.

The WHO Cholera Rapid Diagnostic Test (RDT) Target Product Profile outlines the key requirements for developing improved cholera RDTs. It highlights the need for fast, accurate, and easy-to-use tests for early outbreak detection in resource-limited settings. The document sets desired and acceptable
...
performance criteria, including high sensitivity and specificity, rapid results (under 15 minutes), and usability by non-laboratory personnel. The tests should be affordable, stable in extreme conditions, and require minimal training. The goal is to enhance cholera surveillance and outbreak response, ensuring quick containment and improved public health outcomes.

Cholera epidemics continue to be a major public health problem in many countries around the
world. When epidemics strike, they can spread rapidly. The disease can also evolve quickly;
patients with severe disease can die of dehydration hours after showing the first symptoms of
cholera.
