Disclosure

  • I have nothing to disclose

International Travel with Kids

addresses and phone numbers of the following:

Immunizations for Travelers

  • General principles
  • Required
  • Recommended

Immunizations: General

  • Make sure current on routine
  • Anticipate risk of exposure
  • Season, Location and Type of travel
  • Traveler specific issues
  • PCP can do all (easily) except

– YF, JE, rabies

Immunizations: Required

  • Yellow Fever

– For endemic countries or regions – Sub-Saharan Africa, Tropical So America –

  • r if traversing

– Live virus – contraindicated if immune-comp – For 9 mos or older, contraindicated < 4 mo

  • Meningococcal vaccine
  • Required for pilgrims to Hajj age 15
  • r older

Immunizations: Recommended

  • Routine immunizations need to be UTD
  • Hepatitis A (common vaccine preventable)
  • Meningococcal

– Recommended for Sub Saharan meningitis belt in dry winter months of Nov-June

  • Typhoid

– Vi polysaccharide, IM, 2y/0; Ty 21a, oral, 6 yr)

  • Rabies (risk determined)

4/18/2013 3

Immunizations: Planning

  • Hep A: 0, 6 mos
  • Rabies: 0, 7, 21-28d
  • JE: 0, 7, 14-30d (delayed hypersensitivity

up to 10 d)

  • Typhoid: IM x1, PO over 7 d; 2 wks before

exposure

  • YF: SQ 10 d before travel (will need

referral to YF licensed provider)

Outbound: Issues to anticipate

  • Malaria

– Bite prevention – Meds

  • Travelers diarrhea

– Avoidance – Management

Malaria

  • 3 M cases worldwide
  • ~1800/yr in US civilians

– 59% in Sub Saharan Africa – 19% Asia – 14% Caribbean, Central and So America – 7% other

Malaria: Prevention

  • Mosquito bite avoidance

– Anopheles are dusk to dawn feeders – avoid exposure – Repellents – DEET (20-30%) – Long sleeves, pants – Permethrin-treated mosquito netting

  • Chemoprophylaxis

Malaria: Resistant P. falciparum

  • Chloroquine-resistant P.

falciparum

– Africa, Asia, tropical So. America

  • Chloroquine-sensitive P.f.

– Mexico to Costa Rica;

  • So. South America

– North Africa, Turkey-Iraq, Soviet republics, Korea

4/18/2013 4

Malaria Chemoprophylaxis

  • Mefloquine

– infants (5 kg) and children

  • Malarone (atovaquone-proquanil)

– toddlers (11 kg) and children

  • Doxycyline

– children >8 yr

  • Chloroquine

– infants and children

Malaria: terminal prophy

  • Primaquine

– Used to eliminate hepatic reservoir of P vivax and P ovale – Contraindicated in G6PD def (test if at risk) – Used in patients with prolonged exposure

Traveler’s Diarrhea

  • Most common travel health problem

– Fecal-oral transmission

  • Bacteria (80%)

– ETEC, campylobacter, salmonella, shigella

  • Viruses

– rotavirus, norovirus

  • Parasites
  • Giardia, amoeba, cryptosporidium

TD: Prevention

  • Risk reduction

– “Cook it, peel it, boil it or don’t eat it” – Advise bottled drinks, no ice

  • Prophylaxis

– bismuth subsalicylate: (65% effective) – Antibiotic prophylaxis: (90% effective)

  • Short-term manage with loperamide with Abx as

back up – Cipro, azithro (esp SE Asia), rifaxamin

TD: if it happens

  • Assessment of fluid losses
  • Assessment of Clinical severity

Assessment of dehydration in infants (Modified from CDC)

SIGN MILD MODERATE SEVERE GENERAL Thirsty, agitated Thirsty, irritable Less responsive, rapid respiration FONTANELLE, EYES Normal Sunken Very sunken TEARS Present Absent Absent MUCOUS MEMBRANES Slightly dry Dry Dry URINE OUTPUT Normal Reduced None for several hours

TD: if it happens

  • Assessment of clinical severity

– Mild (1-2/24h, minimal sx, watch hydration) – Moderate (>3/24 hr, add loperamide) – Severe (mod-severe abdominal pain, bloody, fever)

  • Start antibiotics, maintain hydration

Inbound

  • GeoSentinel survey
  • Clinician-based surveillance of ill child

travelers in travel clinics worldwide

  • 1997-2007

»Pediatrics 2010

Demographics

  • 1840 children
  • Age evenly distributed 0-5, 6-11, 12-17
  • 14% req’d hospitalization, highest < 5y/o
  • 40-45% were <7 d from travel
  • c/w adults, less likely to have pre-travel

information

Clinical Syndromes

  • 21 broad syndromic categories identified
  • 93% in 5 categories:

–Diarrheal disorders (28%) –Dermatologic disorder (25%) –Systemic febrile illness (23%) –Respiratory disorders (11%) –Non-diarrheal GI disorder (7%)

Syndrome: Diarrheal Disorder

  • Diarrheal illness: N Africa, Middle East

Final Thoughts

  • Travel advice within the purview of PCP
  • Handouts, checklists can be developed (or

modified from existing)

  • Most vaccines can be given in ofc (x YF)

with pre-planning

  • Prophylaxis can be rx’d
  • Anticipatory guidance relating to most

common conditions can be provided.

Travel: Summary

  • 1. Pre-travel advice/guidance by the PCP may prevent some

adverse health outcomes.

  • 2. Custody issues may arise with a sole parent and children

crossing international borders.

  • 3. Malaria prevention - bite avoidance and

chemoprophylaxis - should be instituted for all family members.

  • 4. Traveler’s diarrhea is a common problem in most

developing countries.

  • 5. Workup for illness upon return from international

destinations needs to be primarily guided by areas visited.
