'Don't Ignore Tick-Borne Lyme Disease'

As we venture outdoors more this summer, the Public Health Agency has issued a reminder about tick bites and the potential effects of Lyme disease.

The serious and debilitating bacterial infection can originate with tick bites.

Dr Michael Devine, Consultant in Health Protection at the PHA, explained: "The earliest and most common symptom of Lyme disease is a pink or red circular rash that develops around the area of the bite, 3 to 30 days after someone is bitten. The rash is often described as looking like a bull's-eye on a dart board. You may also experience flu-like symptoms such as tiredness, headaches and muscle or joint pain. If Lyme disease is left untreated, further symptoms may develop months or even years later."

Ticks are tiny spider-like creatures, which feed on the blood of animals and sometimes people. Anyone involved in outdoor activities in the countryside, parks or gardens where wildlife such as squirrels and hedgehogs is present may be at risk of tick bites.

Cases of Lyme disease are often acquired through recreational activities including dog walking, camping, hiking and mountain-biking, where tick exposure is more likely.

The best way of preventing Lyme disease is to avoid being bitten when you are in grassy or woodland areas known to have a high tick population. The following precautions might help to prevent Lyme disease:

• walk on clearly defined paths to avoid brushing against vegetation where ticks may be present;

• wear light-coloured clothing so that ticks crawling on clothing can be spotted and brushed off;

• use an insect repellent that can repel ticks and prevent them from climbing onto clothing or attaching to skin (always follow the manufacturer's guidance);

• wear long trousers and long-sleeved tops to reduce the direct exposure of ticks to your skin, making it more difficult for them to find a suitable area to attach.

Dr Devine added: "Late spring, early summer and autumn are peak times for tick bites, which coincides with people venturing outdoors in the warmer weather. It's important that people take preventative measures against tick bites and also look out for ticks after visiting affected areas.

"Lyme disease can be difficult to diagnose so it is important to get medical advice if a rash or other symptoms develop within a few weeks of a tick bite as early treatment can prevent progression to chronic disease."

Currently there are no vaccines to defend against tick-borne disease in the UK and Ireland. Therefore, the best defence is to avoid being bitten.

Only a small number of ticks are infected with the bacteria that cause Lyme disease. A tick bite can only cause Lyme disease in humans if the tick has already bitten an infected animal. However, it's still important to be aware of ticks and to safely remove them as soon as possible, just in case.

If you find a tick on your or your child's skin:

• remove it by gently gripping it as close to the skin as possible;

• use a pair of tweezers that won't squash the tick (such as fine-tipped tweezers), or use a tick removal tool (available from pet shops or vets);

• pull steadily away from the skin without twisting or crushing the tick;

• wash your skin with water and soap afterwards, and apply an antiseptic cream to the skin around the bite;

• don't use a lit cigarette end, a match head or substances such as alcohol or petroleum jelly to force the tick out (as this may cause the tick to regurgitate potentially infected material into the skin, which may increase the risk of infection).

Some veterinary surgeries and pet shops sell inexpensive tick removal devices. These may be useful if you often spend time in areas where there are ticks.
