Poliomyelitis All travelers arriving from polio-endemic countries and re-established transmission countries, namely, Afghanistan, Chad, Nigeria and Pakistan regardless of age and vaccination status, should receive 1 dose of oral polio vaccine (OPV). Proof of polio vaccination at least 6 weeks prior to departure is required for visitors from polio-endemic and re-established transmission countries to apply for entry visa for Saudi Arabia and travelers will also receive 1 dose of OPV at borders points on arrival in Saudi Arabia. The same requirements are valid for travelers from recently endemic countries at high risk of re-importation of poliovirus, i.e. India. All visitors age under 15 years travelling to Saudi Arabia from countries reporting polio following importation or due to circulating vaccine-derived poliovirus in the past 12 months (as of mid-February, 2013, see list below) should be vaccinated against poliomyelitis with the OPV. Proof of OPV or IPV vaccination is required 6 weeks prior to the application for entry visa. Irrespective of previous immunization history, all visitors under 15 years arriving in Saudi Arabia will also receive 1 dose of OPV at border points. Polio cases related to wild poliovirus importation or to circulating vaccine-derived poliovirus have been registered during the past 12 months in the following countries: Chad, Kenya, Niger, Somalia and Yemen. 4- Seasonal Influenza: The Saudi Ministry of Health recommends that international pilgrims be vaccinated against seasonal influenza before arrival into the Kingdom of Saudi Arabia, particularly those at increased risk of severe influenza diseases, including pregnant women, children under 5 years, the elderly, and individuals with underlying health conditions such as HIV/AIDS, asthma, and chronic heart or lung diseases. In Saudi Arabia, seasonal influenza vaccination is recommended for internal pilgrims, particularly those at risk described above, and all health-care workers in the Hajj premises. --More 12:36 LOCAL TIME 09:36 GMT تغريد
