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 mainly by Aedes mosquitoes; an infection may be asymptomatic or become severe.Parasitic disease transmitted by some Anopheles mosquitoes, mainly in tropical areas.Arbovirosis transmitted by Aedes mosquitoes, often marked by fever and sometimes prolonged joint pain.
PreventionReduce larval gites and protect against stings according to local recommendations.Protection against stings and chemoprophylaxis depending on the destination and medical opinion.Disposal of stagnant water and personal protection against stings.

Diagnosis and monitoringThe 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.Appropriate parasitological research can confirm infection and guide management. The assessment shall take into account the territory, dates and species concerned. Previous drug prevention does not preclude infection.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
  • Dates and territories of stay
  • Fever onset, evolution and drinking capacity
  • Specific itinerary and dates of stay
  • Fever onset and associated signs
  • 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.
