Faced with this situation, the national and provincial portfolios recommended that all health teams strengthen the clinical-epidemiological suspicion of paratyphoid fever in people who meet the case definition and inform and sensitize the population about prevention measures and early warning against the appearance of symptoms.

The objectives of epidemiological surveillance are to detect cases early to implement diagnosis, treatment and control actions; allow and direct epidemiological research aimed at interrupting the transmission of the disease.

The Salta Ministry of Health recommended, given the increase in temperature -before the arrival of summer- to take precautions in the handling of food, since bacteria enter the body through the ingestion of contaminated water or food such as meat bovine and avian, eggs, milk or mayonnaise, as well as fish and shellfish.
