Mosquitoes, Malaria

The Malaria Monster

I felt like once I got to South America I wasn’t the only one who wanted to do the snacking.  Whether it was spiders, bed bugs, ants, fleas, the occasional bat, or MOSQUITOES, everything wanted to eat me.

The threat is real people!!!!!

Mosquitoes are the bane of every traveler’s existence.  Not only do they cause those nasty, itchy welts, but they can also kill you with one little bite.  Mosquitoes are considered the deadliest “animal” in the world.  The Anopheles mosquito, in particular, is the most dangerous because it transmits Malaria, which kills more than one million people every single year!   I found it very interesting to find out that only female mosquitoes bite people.  Females need the protein in blood to help their eggs develop.  The average mosquito’s lifespan is less than two months but under ideal conditions, females lay eggs about every THREE days.  No wonder why she bites!

What is Malaria?

Malaria occurs as a result of a bite from an infected Anopheles mosquito, a mosquito infected with Plasmodium parasites.

Following a bite, the parasites enter the person’s bloodstream and quickly migrate to the liver, where they rapidly multiply before re-entering circulation to invade the red blood cells. There, they continue to multiply until the cells burst, releasing large numbers of parasites back into the blood. It is the sudden release of vast numbers of parasites that causes the classic high fevers associated with malaria.

Symptoms usually appear 10 days to 4 weeks after infection though some people start to feel ill as much as a year later.  People tend to experience flu-like symptoms such as chills, headache, muscle aches, and tiredness. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells. If not promptly treated, the infection can become severe and may cause kidney failure, seizures, mental confusion, coma, and death. If you have been traveling and experience any of these symptoms, seek medical attention right away.


How to combat the vampires!????

1: Insect Repellent-

DEET is a traveler’s best friend even though the chemical is known to melt plastic. 30% DEET is known to repel insects for 4-6 hours.  I often only sprayed it on my clothes and then used this great cream called Ultrathon Insect repellent for any skin that was showing.  I would say no matter what chemical you choose, wash it off as soon as you can!

Note: Make sure you apply Ultrathon before your sunscreen.

Garlic and Lemon: You are probably laughing right now but after staying in the rainforest, I learned that the local indigenous people mix garlic and lemon and cover their bodies in it.  It also makes a great salad dressing!

Permethrin: This product was developed especially for application to clothing. Permethrin bonds to clothing where it remains repellent to insects. Reports vary as to how long treated clothes remain repellent –2 weeks to 6 months (5-20 detergent washings).


How do I apply Permethrin?

-One can of Permethrin will treat several outfits – shirts, shorts, and socks.

-Spread out all of the clothes to be treated on a flat surface. Hold the can approximately 12 inches away from the clothing. Spray the clothing using sweeping motions until the clothing is moist. Pay close attention to cuffs and collars. Turn the clothes over and repeat the process. Hang up the clothes and allow them to dry thoroughly.

-Repellent properties will last longer if clothes are sealed in a resealable plastic bag until use.

-Treat mosquito nets in the same manner as above.


 2: Mosquito Nets-

If you plan on sleeping outside, a mosquito net is a must! I swear just being inside of this little cocoon will make your sleep so much more peaceful.  Not to mention, when you wake up in the morning you can see some of the creatures caught in the net that were trying desperately to eat you.

Most places in the rainforest will provide you with a mosquito net.  It’s never a bad idea to purchase one ahead of time that is pre-treated with permethrin, but it’s also something you can pick up on your travels.

3: Long-sleeved, light colored, loose clothing and socks-

The last thing I wanted to do was wear long sleeves and pants in 90-degree weather with %100 humidity…in fact, I didn’t want to wear any clothes at all!! Alas, walking around in my birthday suit (though tempting) might have been terribly awkward since I am not on this season of Naked and Afraid and being covered makes it much more difficult for the skeeters to make you their favorite dinner guest.

Another “hot” fashion trend is sticking your pants into your socks.  At first I thought I was too cool for this trend but quickly learned that my ankles are prime mosquito real estate.  I quickly adopted the style and was very thankful that I did.

Lastly, dress in light colored, loose clothing because not only do skeeters see dark objects more easily than light, but they use smell and heat to find their blood meal and you are more likely to get sweatier in dark clothing.

4: Anti-malarials-

Due to growing immunity from mosquitoes, different tablets work best in different areas of the world. These are the five main anti-malarial tablets you’ll be likely to be prescribed.

Chloroquine – Start one week before travel and continue for 4 weeks after you return. Can be taken for periods exceeding 5 years. Can cause nausea and mouth ulcers.

Paludrine – Start one week before travel and continue for 4 weeks after you return. Can be taken for periods exceeding 5 years.

Mefloquine – Start 2.5 weeks before travel and continue for 4 weeks after you return. Can be taken for up to one year.

Doxycycline — Doxycycline is recommended to be used in Southeast Asia and in chloroquine-resistant areas. You should start taking the tablets (100mg a day) 2 days before you arrive and continue taking them for 4 weeks after you leave the area. Doxycycline can be taken up to 6 months and usually have very few side-effects. It can make you very prone to sunburn and it’s recommended you don’t sunbathe whilst taking these.

Malarone – Start 2 days before travel and continue for one week after your return. Can be taken for up to one year.

Hopefully this article was helpful for all your mosquito needs.  And now to quote Lil John “ah skeet, skeet, skeet, God Damn!” Sorry, I couldn’t help myself.

Vaccinations

The “Prick” that could save your life: VACCINATIONS

There are lots of pesky bugs out there that can make you really sick.  “Ain’t nobody got time for that!”  Go to the CDC website to double check what vaccinations are recommended for the countries you are traveling to.  Many countries require a Yellow Fever vaccination certificate in order to enter their borders.

You must remember to factor in the cost of travel vaccinations into your overall budget.  Some vaccinations such as Hep A and B and Tetanus should be covered by your insurance. YAY OBAMACARE! Some of the other vaccinations can be quite pricey.  I think I spent an extra $300 making sure my vaccinations were up to date, so that is definitely something that you want to consider when making your budget.

I also want to point out that a really great place to get travel vaccinations in Los Angeles and around the country is Passport Health . They got my boyfriend and I an appointment very quickly, were extremely knowledgeable, and also had the last vials of the yellow fever vaccination in the entire city.

Depending on where you’re buzzing around the world here is a list of some of the preventable illnesses you can get.

Hepatitis A: Present in all countries with poor sanitation and public hygiene.

Hepatitis B: Found in South East Asia, the Middle East, South and Western Pacific and parts of the Caribbean.

Tetanus: present WORLDWIDE!

Diphtheria: Found in most of sub-Saharan Africa, parts of South East Asia and South America.

Typhoid: Present worldwide, however it is worse where food and water may be contaminated with sewage — in Africa, Far East and South America.

Yellow Fever:  Present in tropical Africa and South America. You may be required to show a Yellow Fever vaccination certificate to enter certain countries if you are traveling from an infected area.

Polio: Found in developing countries in Asia and Africa.

Japanese B Encephalitis: Occurs following the rainy season in China, regions of Nepal, northern Burma, eastern and southern states of India, northern Sri Lanka, northern Thailand, Laos and Vietnam. Occasional outbreaks have been reported in Malaysia, Indonesia, Korea, Singapore, southern parts of Thailand, southern Sri Lanka and all of India.

Rabies: At great risk in Asia, Africa and South America.

Tick Borne Encephalitis: Found in European Russia, Austria, Hungary, the Balkans, Czech Republic, Slovakia and Scandinavia. It can also be found in eastern parts of China.


How are these diseases transmitted?

Hepatitis A– Associated with poor hygiene and sanitation and is transmitted by infected food and drink and personal contact.

Hepatitis B- Hepatitis B is a blood borne viral infection that is spread through infected blood, contaminated needles, etc.

Tetanus/Diphtheria/Pertussis– Diphtheria is transmitted through respiratory droplets, personal contact and contaminated clothing, bed linen etc. Tetanus spores are present in the soil worldwide and the disease is caused from contaminated wounds.

Typhoid– Associated with poor hygiene and sanitation and is transmitted by infected food and drink and by the fecal oral route.

Yellow Fever – This is a serious viral illness spread by the bite of an infected mosquito.

Polio– Poliovirus is usually spread from person to person through infected feces entering the mouth.  It may also be spread by food or water containing human feces and less commonly from infected saliva.

Japanese B Encephalitis– This is a rare but serious insect borne disease that is transmitted by the bite of an infected mosquito.

Rabies – The risk to travelers in endemic areas is proportional to their exposure to potentially rabid animals. Travelers in tourist resorts are at very low risk.

Tick-Borne Encephalitis– This is a viral infection transmitted by the bite of an infected tick and rarely from drinking unpasteurized milk.


When should I get my vaccinations and how long do they last?

Hepatitis A

A single vaccination provides immunity up to one year and is effective after two to four weeks.  A booster dose is given between six and twelve months of the original and gives immunity up to ten years-effective immediately.

Hepatitis B

The vaccination is given as a course of three injections, the second 28 days after the first and the third 6 months after the second. Immunity lasts for at least five years.

Tetanus/Diphtheria/Pertussis
Tetanus immunization is generally required before starting school. Five doses of vaccine are recommended. When over ten years has elapsed since the primary immunization course or the person is travelling to a country where tetanus is indicated, a tetanus booster should be given. This could either be in the form of a “Td vaccine” which is a 2-in-1 vaccine that protects against tetanus and diphtheria and is required every 10 years or in the form of the new “Tdap vaccine” one time. The Tdap vaccine is a 3-in-1 vaccine that comprises tetanus toxoid, reduced diphtheria toxoid and a cellular pertussis.

Diphtheria vaccination is also one of the recommended childhood immunizations which should begin during infancy. A diphtheria booster should also be given if travel is for more than one month to a country or region where it is indicated.

Typhoid

One dose is effective after two or three weeks and immunity lasts up to three years

Yellow Fever

The vaccination must be given 10 days before leaving and is good for ten years. This is a live vaccine and it has to be given on the same day as other live vaccinations (Polio), or 3 weeks apart.  Every once-in-awhile the U.S experiences a shortage of the yellow fever vaccination so you want to make sure you get this with ample time before your trip.  REMINDER: Carry your certificate with you.

Polio

Polio vaccination is another one of the recommended childhood immunizations and vaccination should begin during infancy. A polio booster may also be advised for travel to certain countries if ten years has elapsed since the primary course.

Japanese B Encephalitis

The vaccination consists of two doses, the second administered 28 days after the first dose.  The persistence of the immunity is unknown.

Rabies

Vaccinations against rabies is carried out in two distinct situations:

  1. To protect those who are likely to be exposed – Pre-exposure.
  2. To prevent establishment after exposure has taken place – Post-exposure.

The vaccines used for pre and post exposure are the same but the schedule of administration is different.

For pre-exposure three doses are given on days 0, 7 and 21 to 28 (a few days’ variation in timing is not important). A booster dose is required every two to three years depending upon risk of exposure.

Tick-Borne Encephalitis

The course comprises three doses. The first dose on day 0, the second dose one to three months later and the third dose five to twelve months after the second. It gives a 97% protection rate and lasts for three years.

The booster comprises a single dose after no more than three years. It is effective immediately and subsequent boosters should be given at three to five year intervals.

Get vaccinated. 

A disease that can cause complications for a lifetime isn’t a souvenir you want to bring home.
