Today on the Ordnance Survey blog we have a guest post from Wendy Fox from BADA-UK.

As summer (such as it is) progresses, many of us are getting out and about to enjoy the great outdoors. Of course, there are many health and safety aspects that we should be aware of (such as preparing for adverse weather and preventing walking/running injuries etc.) but how many people think about ticks when it comes to getting out and about?

Vampire ticks: The scourge of the countryside! Are they really that dangerous? Well the press would have us believe so, with recent headlines such as, “Alert over rise in killer ticks”, and “The European Invader that’s after your blood”.  Although not quite relatives of Dracula, lurking in every darkened corner, ticks are blood-sucking parasites and they can transmit a range of diseases to people, domestic animals and wildlife.

As a victim of one such disease called Borreliosis (Lyme disease), I am able to speak from personal experience, and with understanding when it comes to the more serious consequences of infection. My disease was not diagnosed or treated promptly and so had the opportunity to become deep-seated within my central nervous system, heart and other organs, causing irreversible tissue damage. It has left me a paraplegic, blind in one eye and partially sighted in the other, and in need of full-time care due to the extensive nature of my health problems. From the bite of a tiny tick, that’s a lot of consequences!

What perhaps resonates with me most powerfully is that these effects were almost certainly avoidable, had I known some basic facts about ticks. Like many people, I had been taught that the most important thing about tick removal was to get the tick to back out itself, so that mouth parts would not be left in the skin. What I didn’t realise was that burning, freezing or smothering a tick in substances such as petroleum jelly, oils and spirits can result in the tick regurgitating infective fluids before it backs out or dies. The current advice from all official bodies in disease prevention is that these methods should not be used.  Pity I didn’t know that when I was zapping ticks off me with a cigarette end!

The truth about ticks and their removal

Ixodes ricinus - the Castor Bean Tick

There are only two safe methods of tick removal:

  1. With a bespoke tick-removal tool (studies have demonstrated the ones designed like a crochet hook to be the most effective, especially with the tiny sub-adult ticks) and the manufacturer’s instructions should always be followed.
  2. With fine-pointed tweezers (grasping the tick as close to the skin as possible and steadily pulling / levering the tick outwards without jerking or twisting. Twisting with tweezers exerts too much pressure on the mouth parts and they may break off, whereas some tick removers are designed to twist without this risk).

Removal with fingers may risk compression of the tick’s body, squeezing out infective fluids, and squashing or scratching off a tick may spill these fluids. Additionally, some ticks carry infective agents which can enter through breaks in the skin.

There are ways that you can reduce the risk of being bitten in the first place. Various insect repellents on the market are effective against ticks, although these parasites are tenacious and nothing is 100 per cent tick proof.

Depending on your chosen activity, wearing the right kind of clothing can lower the risk of being bitten. Light-coloured clothing allows you to see any ticks on you before they have had a chance to get to your skin and attach themselves. Garments with elasticated waistbands and cuffs will also help to deter them and simply tucking trousers into socks or wearing gaiters helps to create a barrier.

Ticks are more often on low vegetation (about 18 inches high) and they wait until a suitable host (animal or human) brushes past and they latch on with special hooks on their legs. They can also drop onto a host from low branches. Then they will wander around looking for a place to feed, so they can be found attached anywhere on the body (including places too personal to mention)!

Short of wearing a frog suit, it is almost impossible to completely deter ticks.  It is therefore advisable to check yourself as regularly as possible (a shower or bath at the end of the day is a good opportunity for a thorough look). The more you check, the more likely you are to find a tick before it attaches, or soon after. The longer the tick is allowed to feed the more saliva it pumps in to numb the bite area, keep the blood flowing and prevent inflammation. Each drop of saliva potentially carries a range of infective agents and some people can contract multiple infections from a single bite. Of course, you may be happy wandering the countryside in a wetsuit (each to their own), but for most of us it’s preferable to just take simple, sensible precautions and to do a regular tick check.

Had I known about ticks in Britain and Ireland being vectors of disease prior to my becoming infected, I still think I would have been a fully paid-up member of the “it won’t happen to me” and “I’ve been out and about all my life and never had a problem” brigade.  I can understand why people feel this way but, even in the years since I became infected, there has been an increase in the incidence of disease cases, particularly Lyme disease. In Scotland, cases rose from just 28 in 2001 to 605 in 2009 and in England and Wales from 268 to 973 (all figures being the last available and provisional data).

Authorities acknowledge that the recorded data is incomplete.  The Health Protection Agency estimate that an additional 1,000 – 2,000 cases in England and Wales go unrecorded per annum and Dr. Darrell Ho-Yen of Scotland’s Lyme disease testing service believes that the true incidence for Scotland could be ten times the number recorded. Reasons given for the discrepancy between reported and estimated case numbers include wrong diagnoses, tests giving false results, sufferers who weren’t tested, people who are infected but asymptomatic, failures to notify and infected individuals who don’t consult a doctor.

But why is it that when I was diagnosed I didn’t know anyone with Lyme disease, yet now every second person I meet seems to have had or got it, or knows someone who has? Studies have demonstrated various contributing factors. Changes in farming practices and the climate have allowed ticks to complete their life-cycle faster, increasing their population. An increase in host-animal species has allowed their distribution to increase too, while our residential dwellings are ever encroaching on the tick’s habitat, bringing them into close proximity with our recreational spaces.  Another contributing factor is that more people are involved in outdoor pursuits which bring them into contact with prime tick habitat.

At the time I was infected, there wasn’t the availability of information that there is now and even after diagnosis I found my disease to be bewildering and isolating. It was my desire to prevent others from being in the same position that led me to found Borreliosis & Associated Diseases Awareness UK (BADA-UK), along with some fellow sufferers who felt the same. Now in its seventh year, the charity has seen a rise in the appetite for information and the number of people requiring support.

Despite all that has happened to me, my passion for the great outdoors remains. I particularly love taking my camera into the most inaccessible places (for someone confined to a wheelchair, and thanks to a long-suffering husband).

Are ticks the scourge of the countryside? No – they are part of nature’s bizarre and intricate tapestry, but they do need to be given a little respect for they can inflict a nasty bite which may just change your life.

    Many thanks to Ordnance Survey and particularly Wendy for this. As with many people, I also wish I’d known earlier, but want to keep trying to help spread the word.

    I’ve shared on my facebook page and also tweeted.

    I have never bofreo had a tick until today when I found 2 on my legs. I went to the doctor to have them removed. How strange that this article should appear on the very day I get some…

  3. Well done OS and thank you Wendy for an excellent article.

    What a pity I didn’t read something like this prior to my tick bite in 2003 perhaps then it wouldn’t have taken 5 doctors and 3 rheumatologists 4 years to diagnose me.

    My husband Mike Drayson worked all his life in the OS retireing about 15 years ago, sadly he was unaware of the dangers of tick borne illnesses lets hope those now working for the OS are properly informed as part of their training.

    @Becky – so you’ve bought a tick remover so you can do it yourself quickly if it happens again? I hope the doc removed safely and told you what to look out for, as quite often the medical people are also in the dark, unfortunately.

    Thanks very much to OS and Wendy Fox for this article. I’m another Lyme casualty. I was in intensive care with Lyme disease meningitis but am fully recovered now.

    Wendy didn’t mention that the charity provides a range of repellents and the tick removal tools she mentioned. The BADA-UK website (link above) is a one-stop shop for all things tick related.

    Once again a brilliant article written by Wendy who is the best advocate for the promotion of ‘tick awareness’ but still keeping a sensible balance in not being too much of a scaremonger. Our lovely countryside has so much good to offer and with the wonderful unselfish, tireless work of Wendy & her team at Bada-uk generations to come will be able to enjoy in comparitive safety.
    I was very tick ignorant, pulling them off my present & previous dogs as a matter of course until I too become another victim but fortunately for me despite very severe symptoms that were originaly mis-diagnosed I was given the treatment to make an almost 100% recovery.

    Thanks for all of your comments – and a thank you from us at Ordnance Survey to Wendy for writing the article.

    I was reciently bitten by lots of ticks. I went camping in Scotland and removed about 50 over 3 days. I went to the GP and asked as I was well aware of lymes disese and had heard that a course of antibiotics very early on could prevent it. The GP was having none of it and said the risk was so low that they would just wait and see what happened.
    I already have stuff happening with my auto-immune system and didnt want lymes disease aswell. It seems daft not to do preventitve medicince compareed the the cost of getting lymes disease under control once you have it

    I was ‘ticked’ when I was in Armenia in 2006. I quickly developed symtoms and went to my Dr in England. I was refused anitbiotics by three separate Drs within the first 6 months, although I had read about the disease in the outdoor press for years. The trouble was that the tests did not prove positive. I have had typical Lyme symptoms ever since.

    Dogs on beaches is a wonderful activity for the family to engage in, but you need to make sure that your dog is safe from the dangers posed by parasitic ticks when you’re out. These tips are good advice not only for beaches, but for any outdoor adventures. Remember that ticks carry deadly diseases, and are a serious threat to everyone, pets and people alike. ”

    I believe I’ve been bitten by a tick and I’m at the stage where my nerves are being effected I haven’t been diagnosed yet I’m in hospital now. Going to have MRI today but just reading on the net and omg this must be my problem I’ve got a ref mark on right foot and can remember scratching something out my foot weeks ago I’ve had extreme muscle fistula toons in my right leg and calf and buttock atrophy I’m keen to tell doctors what I think is the cause. As I don’t know if any of the blood test they’re doing is for checking for tick related issues
