Why Typhoid in Africa is no vaccine

Typhoid, one of the classic infectious diseases afflicting humanity, is still a relatively common illness in many lower-income and middle-income countries (LMIC).1 The disease is associated with chronic fever that, if not treated, can lead to complications such as intestinal perforation or neurological problems.2

The diagnosis of typhoid is complicated because clinical presentation can be non-specific and can resemble a number of other diseases, such as malaria, typhus, and various viral infections. The current typhoid diagnostic kits are relatively unreliable, and microbial culture from blood or other bodily secretions of the main bacterial aetiological agents Salmonella enterica serotype Typhi and S enterica serotype Paratyphi A remains the gold standard.3typhoid

Microbial culture requires the availability of adequate laboratory facilities, including blood and microbial culture equipment, and appropriate bacteriological expertise. Unfortunately, these are not always present in LMIC settings and the incidence of typhoid in many regions, particularly Africa, remains relatively undefined.

Nevertheless, more than 20 million cases of typhoid have been estimated globally, most of which are caused by S Typhi, with between 200 000 and 600 000 deaths.However, the estimates are compromised by limited epidemiological information and restricted geographical coverage, as well as the problems with diagnosis.

Interest in typhoid has increased in recent years, driven by a number of factors. Multidrug resistance has been increasingly reported as a characteristic of S Typhi isolated in the past decade and from different parts of the globe.

Although there is historical evidence that typhoid has been established in south and southeast Asia for decades, there have been increasing reports of typhoid in different African countries, potentially associated with multidrug resistance.

Portant le même souci de nous informer sans polémiquer,nous ne tairons pas nos droits inaliénables ,car les devoirs s'imposent à nous.Dans cette voie,je compte sur vos commentaires et vos témoignages pour plus de lumière.
