Compare infectious diseases

The same route of exposure may involve very different agents. Compare the mechanisms and prevention, then consult the original records and sources.

What distinguishes diseaseViral infection transmitted mainly by certain ticks and, more rarely, by unpasteurized dairy products.Parasitosis mainly present in Latin America, transmitted by triatomine bugs but also by other routes.Arbovirosis transmitted by Aedes mosquitoes, often marked by fever and sometimes prolonged joint pain.
PreventionVaccination by area and exposure, tick protection and consumption of pasteurized products.Vector control, improved habitat, food security and screening for donations and congenital transmission.Disposal of stagnant water and personal protection against stings.

Diagnosis and monitoringDescribe injections, movements and consumption of raw milk. The medical assessment of a neurological disease seeks the cause; the symptoms alone do not confirm it.A normal examination or absence of signs is not sufficient to exclude infection. Mention the former residences and the results available to organize the appropriate assessment.The search for the virus or antibodies depends on the delay from the symptoms. Dengue and Zika can travel in the same areas and look alike.
Preparing for an exchange with a professional
  • Piqûre and external activities
  • Raw milk, destination and vaccination
  • Countries and habitats used, whether or not old
  • Pregnancy, transfusion and transplant
  • Dates and places of residence
  • Fever onset and joint pain

What this table allows to understand

The selected records cover 2 agent family/families. They share the following routes or contexts in our catalogue: Vector. These associations describe the selected data; they do not measure contagiousness, severity or personal risk.

To review a comparison, choose one row and open the reference for each column. A preventive measure mentioned in one record and absent from another is not necessarily unnecessary in the second situation: the summaries and their scope may differ.

If symptoms occurThe table does not select any test or treatment. A fever after a stay in the malaria area should be reported promptly, even if prevention has been taken.
