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 diseaseSexually transmitted infection that can affect several sites and sometimes evolve without symptoms.Sexually transmitted infection often without symptoms, which can lead to complications of reproductive health; transmission to the newborn is possible at delivery.Sexually transmitted infection evolving in several phases and transmissible during pregnancy.
PreventionPreservatives, screening, prescribed treatment and partner information as recommended.Preservatives, exposure-specific screening, prescribed treatment and partner management as recommended.Preservatives, regular exposure testing and early treatment of affected individuals and partners.

Diagnosis and monitoringThe site of the sampling depends on the contacts: urine or genital sampling does not necessarily cover throat and rectum. A culture may specify susceptibility to antibiotics.Sampling should be consistent with exposed sites. Time frames for post-treatment and re-screening do not answer the same question.The professional interprets several tests and previous results. Some antibodies persist after treatment; their positivity is not sufficient to conclude reinfection.
Preparing for an exchange with a professional
  • Sites and dates of contacts
  • Antibiotics already taken
  • Dates and sites of contacts
  • Previous results and salaries
  • Dates of contact and injuries
  • Serological results and previous treatments

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. 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.
