Republican Scientific and Practical Center of Sports Medicine under the National Olympic Committee of the Republic of Uzbekistan issued a memo to Uzbek athletes due to the threats related to stay at the Olympic Games in Brazil this summer.
It states that the main risk are diseases transmitted by rural insects (gnats, mosquitoes). Among them there are the disease caused by Zika virus, yellow fever, and malaria.
Zika virus has recently gained considerable importance in connection with its shedding in the regions of Central and South America, and Southeast Asia.
On this basis, the Ministry of Health of the Republic of Uzbekistan recommends to observe set of rules of "specific and non-specific prevention." These include vaccination against yellow fever, limiting visits to forest and rural areas.
Doctors do not recommend consuming food and water without heat treatment, cooked in unsanitary conditions or the quality of which is doubtful.
The necessity of limit contact with the local people to prevent transmission of sexually transmitted diseases is also noted.
In case of one or more symptoms of the disease (fever, rash, conjunctivitis, pain in muscles and joints, fatigue) onset within 2-3 weeks after return, it is necessary to address to infectiologist urgently.
Brazil requires the travelers arriving from countries where yellow fever is present to provide the proof of vaccination against yellow fever. Vaccination should be done at least 10 days prior to travel and is valid for 10 years, if there is a constant danger. In the other cases, vaccination is voluntary.
