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 diseaseBacteria that can be worn without symptoms and cause serious infections, especially in the newborn.Sexually transmitted infection often without symptoms, which can lead to complications of reproductive health; transmission to the newborn is possible at delivery.Rare but potentially severe food infection, especially during pregnancy and in immunocompromised people.
PreventionScreening during pregnancy and prevention during childbirth according to local recommendations; rapid management of infection.Preservatives, exposure-specific screening, prescribed treatment and partner management as recommended.Respect targeted food recommendations, conservation temperatures and hygiene rules.

Diagnosis and monitoringMaternal screening and diagnosis of a newborn infection answer different questions.Sampling should be consistent with exposed sites. Time frames for post-treatment and re-screening do not answer the same question.The professional brings together the signs, the field and the samples indicated. The food survey can be complex: exposure is not necessarily limited to the last meal. A recall alert specifies a batch and period, without making a diagnosis.
Preparing for an exchange with a professional
  • Result of pregnancy screening
  • Known drug allergies
  • Dates and sites of contacts
  • Previous results and salaries
  • Label, lot and product recall notice
  • Dates of consumption and onset of symptoms

What this table allows to understand

The selected records cover 1 agent family/families. They share the following routes or contexts in our catalogue: 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.
