Travel Vaccinations: What You Need to Know  

With summer soon approaching, many Canadians are planning their summer vacation. For those who plan on leaving Canada, attention should be paid to not only what vaccinations are mandatory, but which ones are recommended. It is important to remember that not all countries face the same potential outbreaks; for every visit outside of Canada you should consult with your physician as well as reputable travel advisories in order to be informed of any potential health risks.

Certain diseases are far more common in developing countries than in Canada, however as Canadians are usually immunized early in childhood, there is very little risk of becoming infected. Check your childhood immunization chart to make sure you have been vaccinated for diseases such as rubella, tetanus, polio, and diphtheria. While outbreaks of these have not been prevalent in Canada for a long time, epidemics do occur in other countries. If you are traveling with young children, consult with their pediatrician about the status of their vaccinations, as well as any health risks concerning the area of travel.

The most common diseases that you can be vaccinated for and are at risk of acquiring are:

• Hepatitis A and B: Can be caught from "unclean" water, including fruits and vegetables that are washed in this water and ice cubes and is also transmitted by sexual contact. There is a combined vaccine that provides lifetime protection against both Hepatitis A and B consisting of three doses given over a 21 day period.
• Influenza: The flu vaccine in Canada is based on projections of what type of flu will be prevalent for the season. While this is usually consistent with flu outbreaks around the world, it does vary. Timing as well is a factor, as the flu season in the Northern Hemisphere occurs in wintertime; the Southern Hemisphere has their projected flu season during the summer, and flu season typically lasts all year round at the equator. As well, due to the recycled air on airplanes, the risk of catching infectious diseases is quite high.
• Typhoid: Be advised that the vaccination for typhoid only lasts for 3-4 years, and typically only provides 70% protection. Anyone traveling to a country with under-developed water treatment systems and/or sanitation systems should be vaccinated. New Canadians who are traveling back to their homeland are at the highest risk of becoming ill with typhoid.
• Yellow Fever: One of the only vaccinations that is required by health officials to cross international borders. 21 countries in Central Africa as well as South America require a yellow fever vaccination certificate for all entries; 102 countries demand this certificate from anyone who has been in the "yellow fever zones". There is a high mortality rate among people who become infected with yellow fever. The current vaccine only lasts for 10 years, so it is important to keep your immunization records, and be aware of when you need to be vaccinated again.
• Meningococcal (bacterial) meningitis: This is recommended for anyone traveling throughout sub-Saharan Africa, especially if you plan on living closely among the local population. This is a very dangerous disease and is highly contagious; it is passed between people through coughing and/or sneezing. This vaccination is now required for anyone going to Saudia Arabia to participate in the Hajj. As your risk of infection is lower when staying in a quality hotel, you may not need this vaccination. It is a wise idea to consult with a travel health professional in order to determine your individual risk.
• Japanese encephalitis: Is transmitted through mosquito bites, as is malaria and yellow fever. This is prevalent mostly in rural areas of South and Southeast Asia and can be fatal, as well as causing severe neurological damage. It is mostly contracted in the summer months by an evening-biting mosquito and the symptoms are similar to those of meningitis. The vaccine offers protection for 2-3 years; be aware that there have been allergic reactions associated to this vaccine. It is highly recommended for those who plan on spending more than a month in areas that are affected with this disease.
• European tick-borne encephalitis: Has similar symptoms to the Japanese version, but often has more severe consequences. It is a viral infection carried by ticks, and is found in Russia, the former Soviet Union, as well as other parts of Europe, and is most prevalent in the summer months. Anyone planning to stay in these areas for a long period of time should be vaccinated; this vaccine does need to be ordered, so you must plan ahead. It is also important to follow procedures that reduce the risk of being bitten by ticks.
• Rabies: A fatal disease of the brain and nervous system that is transmitted through animal bites, especially dog bites. Rabies is common throughout the world, including North America. Although this vaccine is expensive, it is very safe and effective. For those who have been vaccinated and are bitten by an animal, 2 additional doses are required. However, for those who have not been vaccinated, 5 doses of vaccine and one of rabies immune globulin are required for effective treatment. The rabies immune globulin is not widely available in the developing world, which poses a huge health concern if bitten. It is important to know whether or not this is easily accessible in the country you plan on traveling in, as well, consult with a travel medical professional. This is usually recommended for long-stay travelers, especially those traveling with children.
• Malaria: There is currently no malaria vaccine. There is however, three first-line antimalarial drugs that are recommended to help prevent becoming infected. These drugs should be taken for several weeks or even the day before potential exposure, as well as during the travel period, and for 1-4 weeks after returning. It is important to know that none of these drugs offer 100% protection, so it is important to take safety measures to prevent being bitten by virus-carrying mosquitoes. These include using insect repellants, as well as mosquito netting, screened accommodations, and wearing long pants and long sleeved shirts after dark.

You should consult with your physician as soon as possible when making your travel plans. This will allow you enough time for the slower vaccines to take effect. A 2 month time period is usually recommended to consult with your doctor. Your doctor will have the latest information on any outbreaks, as well as the latest vaccines that are available. As well, it is very important to tell your doctor that you have been abroad if you become ill within 2 months of returning to Canada, in case you have caught a foreign-based illness.

There are also websites that offer the latest information about these diseases globally. The Public Health Agency of Canada offers travelers advisories and/or warnings of any outbreaks throughout the world. This is an important tool when making your travel plans in order to decide if your destination is a safe one. Before booking your travel plans, make sure you have the latest information available about the country/region. Be aware that the health status of a country can and does change; make sure you read all travel advisories every time you plan on leaving Canada.

Antibiotic Resistance in Canadians  

Chances are that at some point in your life, you've taken antibiotics to fight a serious infection. Traditionally antibiotics have been very effective in combating illnesses such as pneumonia, meningitis, tuberculosis, and other infectious diseases. However, misuse and/or overuse can lead to strains of these diseases becoming resistant, and therefore very hard to treat.

There is global concern now as there is an increased finding in antibiotic resistant forms of bacteria, viruses, fungi and parasites that up until now were easily treated. This could potentially lead to outbreaks of diseases that have been assumed eradicated, i.e. tuberculosis. As well, these outbreaks will be more difficult to treat, as they will not positively respond to the standard treatment protocols.

A major cause of this resistance can be traced to misuse of antibiotics; as well the unnecessary prevention of infections in people, plants and/or animals. Germs are living organisms that are capable of adapting to their environment, and often will take on the characteristics of other, more potent germs. This means that overuse of products such as antibacterial soaps can end up causing germs that are not very harmful to mutate into germs that are. It is important to realize that germs that become resistant to one antibiotic are likely to become resistant to another antibiotic.

In order to help prevent your body from becoming resistant to antibiotics, it is essential to use them only as prescribed, and exactly as prescribed. Antibiotics are not effective for treating such common ailments as a cold and/or the flu. If you are sick, and not getting better, you must visit your physician to be properly diagnosed and treated. This will usually involve a culture being taken, in order for your condition to be properly identified; this is important as certain viruses will respond better to certain types of antibiotics. If you are prescribed antibiotics, you must take them exactly as prescribed; even if you are feeling better, it is vital that you finish all the pills prescribed. If you do not finish the cycle of antibiotics, it usually will result in only the weak bacteria being killed off, with the stronger bacteria remaining and possibly growing stronger in order to survive. This will possibly result in a more serious illness that is not going to respond as well to antibiotics.

Using anti-bacterial products kills off "good" bacteria. The human body needs to be exposed to bacteria in order for the immune system to effectively be able to combat them. By killing off the "harmless" bacteria, your immune system does not have the chance to develop antibodies, leaving you more at risk for serious illnesses. Washing your hands with soap and water regularly throughout the day is a great way to reduce your exposure to any harmful bacteria. As well, cleaning products that are labeled anti-bacterial have the same result; using normal products such as vinegar and water will leave your house clean and allowing good bacteria to remain. Proper food handling and preparation will ensure that the bacteria responsible for illnesses such as salmonella are destroyed.

It is also important to be current in your vaccinations. This is the most effective way of reducing your risk of becoming ill and ultimately needing antibiotics. Make sure you discuss this with your physician; remember that vaccinations for adults will differ than those for children. If you do have unused antibiotics in your home, do not flush them down the drain; this increases the risk of these drugs going into the water table. Bring them back to your doctor or pharmacy, where they can dispose of them properly. Never share your prescription with anyone, even if they are exhibiting the same symptoms you have as it's important for everyone to be diagnosed by their own doctor.

Using antibiotics in the proper way still remains one of our best options in treating certain infections and diseases. Make sure that you reduce your chances of becoming resistant, so that if and when you do need antibiotics, they will be the most effective. It is also important to see your physician as early as possible when you are ill and suspect that it is not just a common cold or flu; not only will you get better quicker, but you will reduce the risk of those around you by decreasing the contagious period of the virus.

Canada to Ban Bisphenol A  

Canada is the first country in the world to declare a chemical used in the manufacturing of hard plastic items as toxic, and is taking steps towards banning its use. Officials for the Canadian health ministry, as well as the Canadian environmental ministry announced the news last week, and said that it is very likely that the use of BPA in the manufacturing of baby bottles will be in effect within the next year. After being declared toxic, a 60 day commentary period comes into place where it seems highly unlikely that the toxic status will be overturned. After this 60 day period, if no new evidence is brought forward that clearly shows the chemical is safe, the chemical can be eligible to be banned within a year.

Health Canada's screening assessment of bisphenol A focused primarily on the impact of the chemical on newborns as well as infants up to the age of 18 months. Exposure to bisphenol A comes primarily from heating baby bottles that contain the chemical, as well as the migration from can liners into infant formula. The current studies show that while the exposure to the chemical is below levels that may pose a risk, the gap between exposure and effect is not large enough. Studies conducted by Environment Canada have shown that even low levels of BPA is harmful to fish and aquatic organisms over time; tests already show that the chemical can be found in waste water and sludge treatment plants.

Bisphenol A is an industrial chemical that is used to make a hard clear plastic known as polycarbonate. This plastic is used in many consumer products such as reusable water bottles, as well as baby bottles. The chemical is also used in epoxy resins, which act as a protective lining for the inside of metal-based food and beverage cans. This lining prevents corrosion of the can to protect the food or beverage from any dissolved metals, as well as helping to preserve the quality and safety of canned foods. The chemical is also used in other products such as medical devices, dental sealants, sports equipment such as helmets, electronics and automotive parts.

Certain studies have shown that exposure to even low levels of BPA during pregnancy, infancy, and/or early childhood may effect normal development. It can also cause sensitivity to the onset of diseases later in life, especially the potential for mammary and prostate cancer. Laboratory studies have shown that when infants are exposed to BPA, it can lead to neurological as well as behavior problems later in the future. However, there does not seem to be any risk associated with the chemical and adult humans.

For parents who use baby bottles to feed their newborn or infant, precautions should be taken. Do not pour boiling water in baby bottles that have BPA, as very hot water causes the chemical to migrate out of the bottle at a much higher rate. Water should be boiled and then allowed to cool to a lukewarm temperature in a non-polycarbonate container before being transferred into the baby bottle. This precaution should also be used when preparing infant formula that comes from cans that contain the chemical. If you are unsure about whether or not the baby bottles you are currently using contain BPA, check the bottom of the bottle. Typically a number 7 can be found in the centre of the recycling symbol. Note that the number 7 is used to denote a broad category; you can only be 100% sure if the container has BPA when the initials PC are beside the number 7. If the bottle has no recycling symbol, there is no way to determine if it is a polycarbonate or not. You can also switch to using glass baby bottles, as well as alternative plastic bottles that do not contain the chemical. As there is no discernable risk in the exposure of BPA through canned drinks and foods, there is no reason to stop using these products.

Health Canada is continuing to study the effects of Bisphenol A, especially in pregnant women as well as infants. However, as the current completed studies have shown some risk, the Department of Health has decided to be "safe, rather than sorry" when it comes to this particular chemical. You can visit the Government of Canada's Chemical Substances website to learn more about this chemical, as well as be informed of the results of new testing as they occur.

Dangers of Mixing Herbal Supplements and Prescriptions  

There is a common assumption that over-the-counter drugs and vitamins are safe because they do not require a prescription. Very few people read the labels and instructions about the safe use of these products, as well as investigating whether or not they negatively interact with other products and/or prescription medications. Many people also do not think it is important to tell their physician about any herbal supplements they are taking because they mistakenly think that herbal supplements are safe; however, these, mixed with other medications, can prove to be very dangerous.

Using herbs for their medicinal properties has been practiced for centuries. The problem is that people assume that because it is a natural remedy, it is 100% safe. While these supplements can definitely be helpful for some health issues, they must be taken in a safe manner, and with your physician's knowledge. Many times people take too much of these remedies, assuming that because they are natural, they can be consumed in high doses.  Herbal supplements and vitamins can be dangerous if taken in higher doses than suggested, the same as prescription medications. People with certain health issues need to be aware that certain herbal properties can exacerbate their condition, even when taken as directed.

Ginkgo biloba is a common herbal supplement that is used for memory enhancement. This is a very common supplement with Canadian seniors as a natural way to combat the effects of aging. However, many are not aware that ginkgo biloba should never be taken by anyone who is taking prescription blood thinners. Ginkgo biloba contains properties that naturally thin the blood; these combined greatly increase the risk of strokes and/or severe bleeding. Dong quai and ginseng are also dangerous for those on blood thinning medications.

 St. John's Wort is an herb that is commonly used to combat mild or moderate depression, but should never be used with prescription anti-depressants, especially those that are serotonin reuptake inhibitors, i.e. Prozac, Serzone, Luvox, Paxil, or Zoloft. This combination causes an imbalance, and can cause symptoms such as feeling weak, tired and confused; totally defeating the purpose of taking the medication to begin with.

Echinacea is a very popular herbal supplement that is designed to fire up the immune system. Millions of people take Echinacea at the beginning of the winter to help ward off colds as well as the flu virus. As well, many products such as cough drops and multi-vitamins contain Echinacea without the consumer's knowledge. Echinacea however, should never be taken by anyone who uses corticosteroids, or any other prescription medication that is designed to suppress the immune system.

Valerian is an herb that is a natural sedative, and is used by people to help those who are suffering from insomnia, or other sleep disorders. It can be dangerous, however, when combined with other sleep aids, either prescription, or over-the-counter, as it can cause over-sedation. As with any other sleep aid products, it should never be combined with alcohol.

Glucosamine is a natural supplement designed to help with joint problems and arthritis. However, many forms of glucosamine contain sodium, which can be very harmful for those who are on a low-sodium diet i.e. those who have high blood pressure. People who are allergic to shellfish may also be allergic to glucosamine.

You may be unintentionally putting yourself at risk if you are taking herbal supplements and/or certain vitamins if you have health concerns such as:

• Problems with blood clotting
• Any type of cancer
• Any form of diabetes
• Enlarged prostate gland
• Epilepsy
• Glaucoma
• Heart disease
• High blood pressure
• Psychiatric problems
• Parkinson's disease
• Immune system problems
• Have suffered or are in danger of suffering a stroke
• Thyroid problems
• Liver problems
• Are scheduled for surgery

It's important to recognize that the vitamin and herbal supplement industry is not as strictly regulated as prescription pharmaceuticals. This means that often warning labels are not included detailing the potential dangers of a certain product, or other drugs that the product may negatively interact with. And while the majority of natural supplements are safe and effective, they must always be taken in the manner prescribed. Taking too much of natural supplements can be harmful, the same as prescription medication. For optimal health results, tell your physician about everything you take, including vitamins in order to prevent any potential negative interactions. You can also do your own research about these vitamins and supplements to learn about the benefits as well as the dangers. Before buying any supplements, talk to your pharmacist, who is aware of all your prescription medications; they will also be knowledgeable about any potential harm.

Preventing Snowboarding Accidents  

Winter sports such as snowboarding or skiing are a great way to stay active during the colder months. It's important though, to make sure you are properly equipped in order to prevent serious injuries. While the number of snowboarding injuries does not surpass injuries incurred while skiing, they do tend to be more severe. The number of snowboarding injuries in Canada has risen drastically in the past ten years, with 88% of injuries being sustained by those between the ages of 10-19, with 80% of those being male. Half of those injuries were fractures, with over 40% being to the arms. While traumatic brain injuries, as well as spinal cord injuries are rare, they are on the rise, probably from the rising rend of acrobatic and high-speed moves.

The U.S. Consumer Product Safety Commission estimates that in 1997 over 84,000 skiing injuries and over 37,000 snowboarding injuries were treated in various American emergency rooms. Out of those injuries over 17,000 were head injuries. Their studies have found that 11 skiing and/or snowboarding deaths could be prevented each year and over 7,000 head injuries could be either prevented or reduced in severity simply by using helmets. Many of these accidents occur due to loss of control; either moving too fast on the slopes or being on a slope that is beyond the skiers/snowboarders ability. In 1999 a new report was released showing that helmet use could prevent or reduce the severity of 44% of head injuries incurred by adults, and 53% of those incurred by children under the age of 15.

It is estimated that 25% of all snowboarding injuries occur during a person's first experience, and almost 50% occur during the first season of snowboarding. This is due to the fact that snowboarding is an extreme sport that requires balance and a stable stance on the board. As both feet are fixed in non-release bindings, ankles are susceptible to being injured as the snowboarder cannot "step" out when falling or colliding. This also leaves the upper extremities at high risk of injury as a person's natural instinct is to outstretch their hands in order to break the impending fall. It is essential that anyone learning how to snowboard takes lessons in order to learn the fundamentals, including how to fall properly in order to avoid these injuries.

It is important to have the right equipment in order to either prevent injuries, as well as lessen the severity of any injuries that may occur. The snowboard you use should be in good condition and is fitted for your weight, size, and skill. Purchase a helmet that is specifically designed for snowboarding; helmets designed for other purposes such as bicycling, will not give you enough protection, as well as being too heavy or bulky which can result in whiplash injuries. Snowboarding helmets consist of three layers and are cut higher in the back than in the front. The outer shell varies depending on the model you choose, but is designed to protect against any objects penetrating the shell. The middle layer consists of polystyrene, which will absorb shock during a fall. The inner layer is simply designed for warmth, so that no other headgear will be required. If your helmet has sustained a major blow, you will need to replace it. Make sure the helmet fits snugly and is comfortable.

Snowboarding boots come in three different types; each differs in the support they give to the ankle and foot. Soft boots are the most common type of boot used and offers good stability as well as flexibility. Hard boots are typically worn by racers. Hybrid boots offer the support of the hard boot, but with the comfort and maneuverability of soft boots. It is important to select the proper type of boot for the style of snowboarding you are participating in. Ankle injuries are more prevalent in those who wear soft boots due to their moderate ankle support; people who wear the hard boots however, are more at risk of knee injuries due to the lack of movement. Make sure that you buy the boots and bindings together as these are inter-related.

Wrist and elbow guards are also important to reduce fractures. Wrist guards that are used for inline skating or skateboarding can also be used for snowboarding. Knee and tailbone pads are very important for beginners, as falling backwards is more apt to happen when learning to snowboard.

If you are traveling to Canada, or are a Canadian traveling outside the country to participate in snowboarding, it's important to make sure that your travel insurance will cover any injuries sustained in this activity. Certain travel insurance policies will not reimburse medical bills that are a result of these types of injuries; you may require Adventure Travel insurance. Make sure to check with your broker before you leave to make sure you have the right coverage.
