S8 L1 - Travel related infections: Malaria, Legionnaires, Typhoid, Paratyphoid, Schistomiasis, Ebola, Zika, Myiasis Flashcards
- *Travel-related infections**
- Occurs when…
- What are NTD?
- Generally, do travel-related infections transfer easily between people?
Occur when: Patients have travelled to another location which has a different set of common diseases – usually a located with a considerable climate difference or within the tropics.
What are NTD? Neglected Tropical Diseases – some travel infections are NTD, due to their high-impact on low poor communities despite being mostly treatable, they aren’t always researched etc
Generally, do travel-related infections transfer easily between people?
Many travel-related infections are easily transmissible from patient to patient
- *Travel-related infections cont.**
- How do you take history from a patient with a suspected travel-related infection?
- What is travel history important?
- What is incubation time?
- What categories of infections are they according to when symptoms begin?
- *How do you take history from a patient with a suspected travel-related infection?**
- Ask about all travel for up to 2 years
- Get exact times of year when the patient was in the country as some countries have different strains of the same microorganism whose prevalence varies by time of year. Therefore, may require different antibiotics etc.
- Healthcare exposure? (could have a resistance organism they’ve picked up from a healthcare setting)
- Pre-travel vaccinations?
- Preventative measures e.g. malaria prophylaxis?
- Been with anyone else who’s been unwell e.g. travel companions?
- What did they do there e.g. freshwater swimming?
- Where did they eat, do they drink bottled water?
- Bitten by anything e.g. dog, mosquito?
Why is travel history important?
Different strains of pathogen in different places in the world – antibiotic resistance
Infection prevention – on the ward and in the lab
What is incubation time?
Time taken from when a person becomes infected until they start to see the onset of symptoms
The category of infection according to when symptoms began:
Acute infection: under 10 days
Subacute infection: 10-21 days
Chronic infection: 21+ days
