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.

Diagnosis and monitoringAn eye assessment evaluates inflammation, the position of the eyelashes and the consequences on the cornea. Symptoms of red eye do not refer to trachoma alone.Specialized tests, including RT-PCR or detection of antigens and antibodies, confirm the infection. Sampling must be secured by trained teams.Blood tests are looking for infection. Specify the location, date of activities and treatment already started to guide interpretation.
Preparing for an exchange with a professional
  • Residence or stay in endemic area
  • Pain, light and vision change
  • Tick and place
  • Slaughter or contact with blood
  • Outings and exhibition area
  • Fever and beginning of 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.
