Conclusions: Stakeholders should tailor the design, content, and implementation of future cholera prevention and control methods to meet the needs of the community. Future educational camping should focus on transmission prevention, including vaccination. Education and sustainable interventions should be implemented to improve water, sanitation, and hygiene.

Conclusion: Our results showed that the sandwich ELASA is sensitive enough for the rapid detection of V. cholerae from other bacteria. PMID: 32994896 [PubMed]

(Wellcome Trust Sanger Institute) The evolution of epidemic and endemic strains of the cholera-causing bacterium Vibrio cholerae in Argentina has been mapped in detail. The researchers used whole genome sequencing to study the bacteria circulating during the 1991-1998 outbreak of cholera in the country. Published in Nature Communications, the data have influenced health policy in Argentina, where whole-genome sequencing is now used to distinguish between pandemic and non-pandemic lineages of V. cholerae bacteria.

This study envisages the characterisation of isolated pathogen from two cholera outbreaks reported in 2018 and 2019 from Bargarh and Rayagada districts of Odisha respectively. Vibrio cholerae O1 were isolated following standard techniques. The different virulent and drug resistant genes were detected by multiplex PCR assays; whereas the ctxB genotypes were characterised through double mismatch amplification mutation (DMAMA) PCR assay. The ctxB genes were further sequenced and pulse-field gel electrophoresis (PFGE) was done on some selected strains. The clinical and water isolates of Haitian variant (HCT) V.cholerae O1 Ogaw...

Authors: Ng QX, De Deyn MLZQ, Loke W, Yeo WS Abstract Yemen has been faced with the worst cholera epidemic of modern times, with more than 1 million suspected cases and 3000 deaths at the time of writing. This problem is largely due to the longstanding civil war between pro-government forces and the Houthi armed movement, which has severely damaged already vulnerable sanitation and healthcare facilities and systems in the country. It is further compounded by a dire lack of basic amenities, chronic malnutrition, and unfavourable weather conditions. Another contributory component may be aerial transfer by cholera-inf...

Volcanic activity (assessed weekly by the SO2 flux of Nyiragongo volcano plume over the 2007 &ndas...

Countries around the world have introduced stringent control measures to stop COVID-19 outbreaks growing, but now many find themselves facing the same situation again. From Melbourne to Miami, the relaxation of measures had led to increasing flare-ups, which in some places has already meant reclosing schools, businesses or travel routes. Within the U.S. and among different countries, places with wildly varying public-health policies have experienced wildly diverse outcomes. Most ominously, infections are rising rapidly in many places where they once were falling. So how do countries avoid an indefinite, unsustainable, cycl...

Abstract In the past two centuries, several fatal infectious outbreaks have arisen in Iran. Presented here is a brief historical account of four fatal epidemics including cholera, plague, Spanish influenza of 1918 and smallpox between1796 and 1979. The lessons from these outbreaks could be helpful for better combatting other deadly epidemics including the present-day disastrous COVID-19 pandemic. PMID: 32894975 [PubMed - in process]

Mujica, C ésar Munayco, Luis Suárez, Cécile Viboud, Gerardo Chowell After being cholera free for over 100 years, Peru experienced an unprecedented epidemic ofVibrio cholerae O1 that began in 1991 and generated multiple waves of disease over several years. We developed a mechanistic transmission model that accounts for seasonal variation in temperature to estimate spatial variability in the basic reproduction number (R0), the initial concentration of vibrios in the environment, and cholera reporting rates. From 1991-1997, cholera spread following a mult...
