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

What distinguishes diseaseArbovirose mainly transmitted by Aedes mosquitoes, with a particular risk of complications during pregnancy.Infection of the liver transmitted by blood and certain biological fluids, which may become chronic.Infection targeting the immune system, controlled by antiretroviral treatment but without common healing to date.
PreventionProtection against stinging, reduction of larval gites and sexual precautions after possible exposure.Vaccination, sterile equipment, donation testing and precautions when exposed to blood.Preservatives, screening, sterile equipment, PrEP or PEP when indicated and effective treatment.

Diagnosis and monitoringViral RNA or antibody tests may be used. Some antibodies react with other flaviviruses, which complicates interpretation and requires the clinical context.Blood tests distinguish different markers of infection and immune response. Their combination interprets with vaccine history and context. A follow-up assessment can assess liver disease and guide follow-up or treatment.A reactive result should be confirmed according to the diagnostic path. After a recent exposure, the time and type of test determine the scope of a negative result. Treatment monitoring measures the viral load and organizes the prevention of complications.
Preparing for an exchange with a professional
  • Dates and regions of travel
  • Pregnancy or pregnancy project
  • Previous results with date and exact name of markers
  • Evidence of vaccination and exposure to blood
  • Date of exposure and type of test performed
  • Full result and delay since exposure

What this table allows to understand

The selected records cover 1 agent family/families. They share the following routes or contexts in our catalogue: Sexual use · Mother and child transmission. 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.
