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 diseaseArbovirosis transmitted by Aedes mosquitoes, often marked by fever and sometimes prolonged joint pain.Arbovirosis transmitted mainly by Aedes mosquitoes; an infection may be asymptomatic or become severe.Viral infection transmitted by mosquitoes in several areas of Asia and the Pacific, rarely responsible for severe encephalitis.
PreventionDisposal of stagnant water and personal protection against stings.Reduce larval gites and protect against stings according to local recommendations.Vaccination according to destination and protection against mosquito bites.

Diagnosis and monitoringThe 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.The choice of test depends in particular on when the symptoms started. Direct detection and antibody testing do not answer the same question. The context of stay and the local circulation of arboviruses participate in the interpretation.A suspicion combines the history of the stay and clinical examination. Confirmation uses specialized tests, including antibodies in cerebrospinal fluid or blood.
Preparing for an exchange with a professional
  • Dates and places of residence
  • Fever onset and joint pain
  • Dates and territories of stay
  • Fever onset, evolution and drinking capacity
  • Rural areas and length of stay
  • Season, accommodation and outdoor activities

What this table allows to understand

The selected records cover 1 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.
