The growth of air travel has diminished the barriers to the spread of yellow fever, posing a threat to regions that have not previously been reached by the disease but are considered receptive, including the Middle East, coastal East Africa, the Indian subcontinent, Asia and Australia. For many decades, vaccination against yellow fever has been required for travelers entering many countries with receptive mosquito vectors in order to prevent the importation of yellow fever virus from a country…

TLDR
Multiple factors should be considered in making decisions about YF vaccination, including specific destination, season of the year, local evidence for YF transmission, likelihood of exposure to vector mosquitoes and individual risk factors for YEL-AVD, with the goal of increasing vaccine coverage for travel to high-risk areas and reducing unnecessary vaccination.

Determinants of Compliance of Travelers with Vaccination and Malaria Prophylaxis at a Travel Clinic
TLDR
Travelers should be aware of required vaccination and malaria prophylaxis before visiting South and Central America and Asia and plans to enhance compliance of the elderly and business travelers should be contrived.

TLDR
With a focus first on ruling out life-threatening disease and subsequently on an informed and efficient path to diagnosis and treatment, clinicians may confidently provide care for this challenging group of patients.
Trends in importation of communicable diseases into Singapore.
TLDR
It is underlines that diseases such as malaria, viral hepatitis and enteric fever occur in Singapore mainly because of importation and the proportion of imported diseases in relation to overall passenger traffic has decreased over the past 10 years.
Japanese encephalitis: is there a need for a novel vaccine?
TLDR
Although rigorous surveillance is lacking in most endemic countries, transmission intensity is probably increasing in Bangladesh, Cambodia, Indonesia, Laos, Myanmar and Pakistan owing to growing human populations, and intensified pig-rearing.
Yellow fever in a Brazilian family returning from vacation in an endemic area: relevant clinical features and epidemiological issues.
TLDR
Three cases of yellow fever are reported in a family traveling from the city of Sao Paulo, Brazil to an endemic area, acquiring the disease and presenting mild-to-moderate symptoms, which alerts to the threat of introduction and spread of YF in the urban cycle, when infected travelers return to non-endemic areas.

TLDR
This was the first documented outbreak of YF in Kenya, a classic example of a sylvatic transmission cycle, and surveillance in rural and urban areas outside the vaccination area should be intensified.

Advanced age a risk factor for illness temporally associated with yellow fever vaccination.
TLDR
It is found that the rate of reported adverse events among elderly vaccinees was higher than among vaccinees 25 to 44 years of age, and two additional deaths among elderly YF vaccinees are found, suggesting enhanced surveillance is needed.
