The incidence of malaria has decreased significantly in travellers to South Asia, and it is reasonable to limit the areas where chemoprophylaxis is recommended.
The most important factors influencing the model were: the proportion of travellers using malaria chemoprophylaxis, the probability of contracting malaria without malaria chemoprophylaxis, the cost of the mefloquine regimen, the decrease in the number of travellers without malaria chemoprophylaxis in the reimbursement strategy.
The one-way sensitivity analysis on the cost of the 80% reimbursement strategy shows the highest sensitivity for the following variables: probability of recourse to malaria chemoprophylaxis, probability of contracting malaria without malaria chemoprophylaxis, cost of mefloquine regimen, the decrease in the number of travellers without malaria chemoprophylaxis in the reimbursement strategy.
Given the likelihood of asymptomatic infection decreases with age, the probability of wild poliovirus introduction in travellers is likely to be approximately 100 times the detected importation rate, or 1/3.6 per month.
This hypothesis was tested in the Nordic tax study, which also covered similar changes in travellers' allowances in Denmark and Finland as well as alcohol tax decreases in Finland in March 2004 (an average tax decrease of 33% on all alcoholic beverages or 44% decrease on spirits corresponding to a 36% lower off-premise retail price on spirits).
Leishmanial infections: a consideration in travellers returning from abroad.
Nervous system infections are among the most important diseases in travellers.
It is important for diagnosis in travellers.
The highest risk was seen in returning travellers from the Indian subcontinent (1,253/100,000 travellers), and the lowest in travellers from the other Nordic countries (3/100,000 travellers).
The highest risks was observed in travellers returning from Bulgaria (129/100,000 travellers), Turkey (110/100,000 travellers and Malta (101/100,000 travellers) (Table 1).
