Zimbabwe strengthens capacity to prevent, control and manage cholera and typhoid outbreaks
- Zimbabwe has undertaken several activities to strengthen the country’s prevention, control and management of cholera and typhoid.
- Following a cholera outbreak in 2018, a National Task force for Cholera Elimination was created to support cholera elimination in Zimbabwe, through a multi-stakeholder approach.

Cholera, typhoid cases in Philippines up in 2022: DOH

- The country logged 7,681 typhoid cases from January to August this year. This is 109 percent higher compared to the same time period last year, DOH officer-in-charge Maria Rosario Vergeire said.
- Vergeire said the onset of the rainy season increases the risk of transmission of water-borne diseases.
Typhoid Detection Technique Improves Diagnostic Sensitivity
- A team at the University of California Davis Health working with international collaborators have developed a new technique to detect typhoid and estimate its incidence in populations over time.
- The approach requires only a drop of blood from a finger prick and involves measuring levels of antibodies against two antigens: Hemolysin E (Hlye) and Salmonella lipopolysaccharide (LPS).
- The method also employs AI to calculate antibody decay, which provides an indication of when someone was originally infected
- “Instead of just taking a sample, looking at the person’s antibody response and saying they’re negative or positive, we can model the antibody decay,” said Kristen Aiemjoy, a UC Davis researcher involved in the study. “We use that decay rate to infer when those people were most likely exposed, which provides vital information about the force of infection.”
Antibiotic-Resistant Typhoid From Asia Is Spreading Worldwide
- Treatment-resistant typhoid originating mostly from South Asia has springboarded across borders almost 200 times in the past three decades, according to new research that underscores the increasing global threat of infections that can evade antibiotics.
- The findings, published in The Lancet Microbe, showed that while resistance to first-line treatments generally declined across South Asia, global issues remained. The number of strains able to overpower macrolides and quinolones, two important types of antibiotics, climbed sharply and frequently spread to other countries, the study found.
- The findings are “a real cause for concern,” said Jason Andrews, an associate professor at Stanford University and the study’s lead author, urging that prevention measures be put in place, particularly in high-risk nations. “The fact resistant strains of S. Typhi have spread internationally so many times also underscores the need to view typhoid control, and antibiotic resistance more generally, as a global rather than local problem”.
Chickenpox and typhoid cases catching up in Ernakulam, India
- Health department officials have stated that typhoid cases are showing a rising trend in Ernakulam. As many as 11 suspected cases of typhoid were reported in May, compared to 5 from the previous month.
- The increase in typhoid cases has been blamed on the pre-monsoon rains that have been continuing for the past one week.
- Authorities expect the typhoid cases to rise even further in the coming months due to the monsoon rains. They have advised people to ensure personal hygiene and avoid having stale food and water from outside.

Outbreaks of typhoid fever confirmed in Western Cape and North West, South Africa
- There are currently four outbreaks of enteric fever, three of them in the Western Cape, the National Institute for Communicable Diseases said on Wednesday.
- There are currently 64 cases of enteric fever in the Western Cape, in three separate outbreaks, 18 in North West, 45 in Gauteng, 12 in Mpumalanga, nine in KwaZulu-Natal, seven in the Eastern Cape, four in the Free State and four in Limpopo.
- Dr Juno Thomas from the NICD said the last big outbreak of enteric fever in the country was in 2005, in Delmas, and was traced to a contaminated water supply.
Study assesses how vaccination against typhoid fever could help avert antimicrobial resistance
- Researchers from Yale University, University of Basel, University of Antwerp, CDDEP and other institutions recently published a study aimed to assess how vaccination against typhoid fever could help avert antimicrobial resistance.
- In this study, researchers present country-specific estimates for the effect of TCV introduction on the burden of antimicrobial-resistant typhoid fever in 73 countries eligible for Gavi support.
- According to Dr. Ramanan Laxminarayan, Study Author, Director, CDDEP, “This study, which is part of a larger research effort to study the effect of vaccines on averting antibiotic consumption, clearly demonstrates the tremendous value of vaccines in addressing AMR. Going forward, vaccines could be a major component of any global strategy to tackle drug-resistant infections.”
- Overall, the key findings of the study are as follows:
- The introduction of routine immunization with TCV at age nine months with a catch-up campaign up to age 15 years was predicted to avert 46–74% of all typhoid fever cases in 73 countries eligible for Gavi support.
- Vaccination was predicted to reduce the relative prevalence of antimicrobial-resistant typhoid fever by 16%.
- TCV roll-out could be especially urgent in places where resistance has emerged and is rapidly spreading. The authors give Pakistan as an example, due to an outbreak of extensively drug-resistant typhoid that has been ongoing since 2016.
