Football World Cup 2014 Health Advisory from Riskpro

  1. 1. Mangesh Sawant Brazil World Cup Football 2014 Health Advisory
  2. 2. Travelers visiting the 2014 World Cup in Brazil will be most at risk of gastrointestinal illness and vector borne infections. Researchers have warned of a possible dengue outbreak in Brazil during the World Cup. The possibility of a large dengue fever outbreak during the World Cup, capable of infecting visitors and spreading dengue back to their country of origin, depends on a combination of many factors, including large numbers of mosquitoes, a susceptible population, and a high rate of mosquito-human contact. Therefore visitors should pay attention to standard hygienic measures to reduce the risk of gastrointestinal illness and protect themselves against mosquito and other insect bites. Riskpro has conducted a risk assessment to identify which infectious diseases present the biggest risks to travelers visiting Brazil during the tournament and the public health implications after the travelers’ return to his home country. Riskpro has also developed the current recommendations regarding the epidemiology and risks of the main communicable diseases and contaminated food and water based diseases. Vector Borne Diseases Diseases spread by mosquitoes such as malaria, dengue and yellow fever are common throughout Brazil. Mosquitoes that bite during the day can carry serious illnesses like dengue and yellow fever while night biting mosquitoes can carry malaria. Mosquitoes are attracted by carbon dioxide, heat and movement. Sand flies can carry diseases such as leishmaniasis and are most active between dusk and dawn. They also bite in the day if disturbed. There are many mosquito species; some species bite during daylight hours (e.g. Aedes spp.), and some are bite from dusk to dawn (e.g. Anopheles spp.). Malaria Malaria is a serious, potentially fatal illness spread by night biting mosquitoes. Malaria is a serious febrile illness caused by infection of red blood cells with Plasmodium sp. parasites: P. falciparum, P. vivax, P. ovale and P. malariae. Symptoms usually appear within in 7-30 days but can take up to one year to develop. Symptoms include high fevers, shaking chills and flu like illness. Without treatment, malaria can cause severe illness and even death. People spending time outdoors including sleeping outside are at higher risk for malaria. Anti malarial tablets are recommended if you are going to any Amazon areas. Travelling on to other South American countries could also put you at risk.
  3. 3. Risk management Risk depends on the specific location, season of travel, length of stay, activities and type of accommodation. Anopheles mosquitoes feed predominantly during the hours from dusk to dawn. No malaria prevention tablets are 100% effective. Taking malaria prevention tablets in combination with mosquito bite avoidance measures will give substantial protection against malaria. Travelers should take mosquito bite avoidance measures as mentioned in the report. Dengue Fever Dengue fever is a major public health concern in Brazil. Disease incidence and severity have increased in the past two decades. From 2000 to 2009, 3.5 million cases of dengue fever were reported Dengue is systemic viral disease caused by a virus that is spread through an infected Aedes aegypti mosquito bite. Aedes aegypti mosquitoes feed predominantly during daylight hours and are most abundant in urban or peri-urban settings. Symptoms include fever, headache, nausea, vomiting, rash, and pain in the eyes, joints and muscles. After a person is bitten by an infected mosquito the symptoms can take up to 2 weeks to develop but usually end in a week. In severe cases, symptoms may include intense stomach pain, repeated vomiting, bleeding from the nose or gums and death. The mosquito that carries the dengue virus can bite during the day and night. Dengue is not usually seen at altitudes above 4,500 feet (1,500 meters). Risk management There is no vaccination or medication to prevent dengue. A previous dengue illness with one of the four dengue virus serotypes does not confer immunity to other virus serotypes. Infection with a second dengue serotype may be a risk factor for the development of dengue haemorrhagic fever. Travelers should take mosquito bite avoidance measures. Yellow Fever Yellow fever is a systemic viral disease and is endemic in most parts of Brazil. Yellow fever is spread through mosquito bites. Symptoms take 3–6 days to develop and include fever, chills, headache, backache, and muscle aches. About 15% of people who get yellow fever develop serious illness that can lead to bleeding, shock, organ failure and sometimes death.
  4. 4. Risk management Travelers should take mosquito bite avoidance measures. Aedes mosquitoes feed predominantly during daylight hours. Administration of yellow fever vaccine should take into account both the certificate requirements under International Health Regulations and the risk of yellow fever at the destination. The lack of a certificate requirement does not necessarily indicate that there is no risk of disease You should receive a yellow card called the International Certificate of Vaccination or Prophylaxis (ICVP) to prove that you have had yellow fever vaccine. Some countries require all travelers to show proof of yellow fever vaccination before they can enter the country. Other countries require proof of vaccination only if travelers have been in a risk area, so if you are visiting multiple countries, the order of travel may be important. There are specific contraindications and adverse events associated with yellow fever vaccine. A careful risk assessment should be made before administration and specialist advice sought as appropriate. Precautions against Mosquito Bites General  Cover exposed skin by wearing long sleeved shirts, long pants and hats.  Use an appropriate insect repellent as directed.  Always follow product directions and reapply as directed  If you are also using sunscreen, apply sunscreen first and insect repellent second.  Use permethrin treated clothing and gear (such as boots, pants, socks, and tents). You can buy pre-treated clothing:  Treated clothing remains protective after multiple washings. See the product information to find out how long the protection will last.  Do not use permethrin directly on skin.  Take particular care at times when mosquitoes are most likely to bite: dusk and dawn and from April until October.  Avoid areas where mosquitoes are likely to be found, i.e. near water including ponds, outdoor swimming pools, lakes and marshes.  Spray onto exposed skin whenever you are in an area where mosquitoes may be present.  If in areas where mosquitoes are likely wear long sleeves, long trousers, socks and closed shoes to minimize skin exposure.  Mosquito bites can be reduced by air conditioning, insect proof screens on windows and doors and spraying the room with insecticide.  Some day biting mosquitoes also transmit infections, so reducing bites at any time is a sensible precaution.  Empty containers of standing water near where you are staying to prevent mosquito eggs from hatching.  Use area repellents if there are mosquitoes in your room.  Avoid unnecessary exposure (including while travelling and when sleeping) in infested areas.  Try to stay in air conditioned accommodation as this reduces the number of insects in your room. Mesh screening on doors and windows also helps, but is not as effective as good air conditioning. Plug-in devices (vaporizers) release an insecticide mist, but you need an appropriate adapter plug for the country you are visiting
  5. 5. Screening and mosquito nets  Travelers staying in accommodation without screening should sleep under a net to avoid being bitten at night.  Mesh size in mosquito bed nets should be no larger than 1.5 mm.  Contact insecticides will kill insects landing on the net and therefore increase the effectiveness. Other preventative measures  A systemic review demonstrated that mosquito coils can decrease bites by repelling and killing mosquitoes. Coils which contain synthetic insecticide should only be used in well ventilated areas and may be useful for some travelers.  Use a bed net if the area where you are sleeping is exposed to the outdoors. Clothing  Wear loose fitting, light colored clothes (insects can reach skin through tight clothing), long trousers and long sleeves. Don’t go barefoot.  Malaria mosquitoes are most active after dark, so it’s important to cover up in the evenings in malaria risk regions.  In tick infested areas avoid shorts/skirts and tuck trousers into socks to stop ticks crawling up your legs  Travelers to areas with a risk of dengue fever infection should cover up during the day if possible, as the Aedes spp. mosquitoes that transmit dengue fever bite during the day.  To avoid bites wear clothing that covers as much of the body as possible such as long sleeved clothing and long trousers.  Mosquitoes may bite through thin clothing, so spray an insecticide or repellent on them. Insect repellents should also be used on exposed skin
  6. 6. Insect Bites Bugs, including bedbugs, fleas, lice and mites can also spread disease. For example; fleas can spread plague, some mites carry typhus (a flu like illness with a rash) and the kissing bug in South America carries a parasite that causes a serious illness called Chagas disease (also called American trypanosomiasis). Reduviid bugs, the vectors of American trypanosomiasis inhabit cracks in the walls and roofs or buildings constructed from mud or thatch in Latin America. For many diseases spread by insects, avoiding bites is the only way to prevent them. Places like jungles and swamps may be highly infested with insects. It is almost impossible to completely avoid bites but by reducing the number of times you are bitten you will reduce your risk of being infected. Some diseases in Brazil such as dengue, leishmaniasis, and Chagas disease are spread by bugs and cannot be prevented with a vaccine. Follow the insect avoidance measures described to prevent these and other illnesses. You can reduce your risk by taking steps to prevent bug bites. What should I do if I am bitten by bugs?  Avoid scratching bug bites and apply hydrocortisone cream or calamine lotion to reduce the itching.  Check your entire body for ticks after outdoor activity. Be sure to remove ticks properly. Removing ticks Ticks need to be removed from the skin carefully with tweezers or special tick removers. Grasp the tick near to the skin and steadily pull it out. Be careful not to crush the tick’s body or squeeze its stomach contents into the bite site. Insect Repellents Advice for travelers  Follow the manufacturer’s instructions carefully.  Apply directly to any exposed areas of skin.  Use a cream/lotion or spray repellent on your hands and then rub onto your face.  Re-apply regularly, especially after swimming and in hot, humid countries, as sweating reduces effectiveness.  Don’t swallow repellent.  Don’t put apply to cuts, grazes or broken/irritated skin.  Wash hands after applying.  If you are using sunscreen, put it on first.  Sunscreen containing repellent is not recommended.
  7. 7. Leptospirosis Leptospirosis is another environmental, zoonotic and water borne concern given the fact that this disease is highly endemic, reported in Brazil, counts for almost 20,000 cases between 2007 and 2011. The disease has been associated with swimming, wading, kayaking and rafting in contaminated lakes and rivers. As such it is a recreational hazard for travelers who participate in outdoor sports in addition to consuming contaminated food and beverages  Be aware of the risk and avoid exposure to contaminated water where possible  All cuts, scratches and open skin lesions should be covered with waterproof plasters.  Do not swallow or drink water that could be infected  Washing and showering after possible exposure may be helpful
  8. 8. Food and Water Safety Eating contaminated food and drinking contaminated water can cause illnesses such as hepatitis A, typhoid fever, and travelers’ diarrhea. Beware of food from street vendors, ice in drinks, and other foods and drinks that may be contaminated. Traveler’s diarrhea Traveler’s diarrhea and food borne diseases are highly common and prevalent. TD is acquired primarily through the consumption of contaminated food or water. Traveler's diarrhea can be caused by bacteria, parasites or viruses. The risk of TD is associated with the water, sanitation, and hygiene environment and practices in specific destinations as well as the handling and preparation of food in restaurants in developed countries. Poor hygiene practice in local restaurants is likely the largest contributor to the risk for TD. Inadequate electrical capacity may lead to frequent blackouts or poorly functioning refrigeration which can result in unsafe food storage and an increased risk for disease. Inadequate water supplies can lead to the absence of sinks for hand washing by restaurant staff as well as direct contamination of foods such as fruits and vegetables washed in contaminated water. Poor training in handling and preparation of food may lead to cross contamination from meat and inadequate disinfection of food preparation surfaces and utensils. Drinking contaminated water is the most common cause of acquiring traveler's diarrhea.
  9. 9. The following methods or products help reduce exposure to contaminated water.  Boiling water is the best method for eliminating infectious organisms  Avoid eating foods or drinking beverages purchased from street vendors or other establishments where unhygienic conditions are present  Avoid eating raw or undercooked meat and seafood  If handled properly well cooked and packaged foods usually are safe. Tap water, ice, unpasteurized milk and dairy products are associated with increased risk for TD. Safe beverages include bottled carbonated beverages, hot tea or coffee, beer, wine and water boiled or appropriately treated with iodine or chlorine  The best means of preventing TD is education regarding food and beverage selection with the goal that the traveler avoid the consumption of high risk products  People often discuss the importance of care in selecting "safe" foods and beverages for consumption  Water should be bottled and sealed, or boiled. Alcohol is OK, but ice cubes are not. Eat and drink safely Unclean food and water can cause travelers' diarrhea and other diseases. Reduce your risk by sticking to safe food and water habits.
  10. 10.

Drink • Water that has been disinfected • Ice made with bottled or disinfected water • Carbonated drinks • Hot coffee or tea • Pasteurized milk • Commercially sealed beverages in cans or bottles and served unopened such as carbonated drinks and drinks made with boiled water and served steaming hot such as coffee and tea are generally safe. • Sealed bottled water produced by a recognized international manufacturer Don’t Drink • Tap or well water • Ice made with tap or well water • Drinks made with tap or well water (such as reconstituted juice) • Unpasteurized milk • Fountain drinks • Fruit juices (if sold by a street vendor)
  11. 11. Precautions Wash  Wash your hands before handling food  Wash and sanitize all surfaces and equipment used for food preparation  Protect kitchen areas and food from insects, pests and other animals  Always wash your hands before eating or preparing food. It is also important to remember to wash your hands after using the bathroom, changing diapers or having contact with animals or sick people. Separate raw and cooked food  Separate raw meat, poultry and seafood from other foods  Use separate equipment and utensils such as knives and cutting boards for handling raw foods  Store food in containers to avoid contact between raw and prepared foods Cook thoroughly  Cook food thoroughly especially meat, poultry, eggs and seafood  Bring foods like soups and stews to boiling to make sure that they have reached 70°C. For meat and poultry, make sure that juices are clear, not pink. Ideally, use a thermometer  Reheat cooked food thoroughly Keep food at safe temperatures  Do not leave cooked food at room temperature for more than 2 hours  Refrigerate promptly all cooked and perishable food (preferably below 5°C)  Keep cooked food piping hot (more than 60°C) prior to serving  Do not store food too long even in the refrigerator  Do not thaw frozen food at room temperature Use safe water and raw materials  Use safe water or treat it to make it safe  Select fresh and wholesome foods  Choose foods processed for safety such as pasteurized milk  Wash fruits and vegetables especially if eaten raw  Use ice made only from purified or disinfected water.
  12. 12. What can travelers do to protect themselves?  Consider purchasing travel health and medical evacuation insurance.  Get vaccinated  Take anti malarial meds  Eat and drink safely  Prevent bug bites  Keep away from animals  Reduce your exposure to germs  Travelers who sleep outdoors or who stay in poorly constructed housing are at greatest risk. Therefore take necessary precautions  Travelers should be advised to avoid outdoor activities especially from dusk to dawn  Talk to your doctor about which medicine is best for you. Emergency If you need emergency medical help dial 192 to ask for an ambulance. Foreigners are entitled to emergency medical treatment in Brazil’s public hospitals, but the public health system, especially in big cities, tends to be crowded. Private hospitals will not treat you unless you have proof that you can pay. Remember to contact your insurance and medical assistance company promptly if you are admitted to a clinic or hospital. Both public and private health facilities in remote regions may be very basic. When you get back There is a possibility that returning travelers will export communicable diseases for example vector borne diseases such as dengue and introduce them to their country of residence. During the World Cup travelers to Brazil may encounter Brazil endemic infections that could be diagnosed after returning to their countries of origin. If you have any symptoms such as fever, flu like illness or persistent diarrhea you should seek immediate medical advice. Make sure your doctor knows you have been to South America. If you travelled to malarial areas an urgent malaria test must be arranged. This is important even if you took anti malarial tablets and have been home for a while. If you are not feeling well after your trip you may need to see a doctor. Be sure to tell your doctor about your travel, including where you went and what you did on your trip. Also tell your doctor if you were bitten or scratched by an animal while traveling. Malaria is always a serious disease and may be deadly. If you become ill with a fever either while traveling in a malaria risk area or after you return home (for up to 1 year), you should seek immediate medical attention and should tell the doctor about your travel history.
  13. 13. Conclusion The health risks whilst travelling to Brazil will vary between individuals and many issues need to be taken into account such as planned activities, length of stay and the general health of the traveler. Many of the problems experienced by travelers cannot be prevented by vaccinations and so other preventive measures need to be taken; for example, consumption of safe food and water and protection from sun exposure and insect bites. There is potential for transmission of imported or endemic communicable diseases, especially those that have an increased transmission rate as a result of close proximity of multiple asymptomatic but infected individuals. Limited food borne outbreaks due to bacterial and viral infections are expected. The risk to be affected by gastrointestinal illness will be reduced by standard hygienic measures. Recently aiming to prevent food borne illnesses during the 2014 FIFA World Cup, Brazil has developed a risk based evaluation tool able to assess and grade Brazilian food services in cities that will host football matches. This tool has been used by the Brazilian sanitary surveillance officers during the inspection of facilities where food services. Riskpro recommends that all travelers attending the 2014 FIFA World Cup take routine health precautions.
