Fractional‐calculus analysis of the dynamics of typhoid fever with the effect of vaccination and carriers

International journal of numerical modelling, 2023
Typhoid fever poses a severe hazard to public health and affects at least 27 million people annually around the globe. It is significant to conceptualize the key factors of the transmission phenomena of this bacterial infection.

Typhoid vaccines

Sahel Medical Journal, 2001
Typhoid fever continues to be a major public health problem in developing countries with about 33 million cases per year. Protective efficacy of traditional acetone/phenol killed vaccines is similar to newer typhoid vaccines (Ty21A and Vi antigen vaccine) but side effects of these newer vaccines are considerably less.

Typhoid immunisation

The Indian Journal of Pediatrics, 1984
Since the desired improvement in the sanitation and nealth facilities is not likely in most areas of the third world in the near future, the necessity for typhoid vaccination cannot be easily disputed. The mechanisms of immune response in typhoid, especially with regard to the local gut factors are poorly understood.

Typhoid fever

The Lancet, 2015
Control of typhoid fever relies on clinical information, diagnosis, and an understanding for the epidemiology of the disease. Despite the breadth of work done so far, much is not known about the biology of this human-adapted bacterial pathogen and the complexity of the disease in endemic areas, especially those in Africa.
