How to treat Tickbite
Fever ! (Credit to an article that appeared in the “GO” (Great Outdoors)
magazine No. 121 which appeared in 1995 !)
Tickbite fever is one of
those diseases that creep up on you when you're not looking and bites hard,
putting you out of action for a week or more. The trouble is, you can be victim
of hundreds of tick bites and the only result will be a rash and some itching.
But, another day you are taking a walk in a wetland close to the urban sprawl
(that is the Gauteng), you get maybe a bite or two, and you come down with
tickbite fever. The villain of the piece is a small tick that carries the germ
Rickettsia rickettsi var pijperi. This bug is transferred to the host via the
bite, or can even be rubbed into the wound when you squash the tick. Once this
germ (a primitive parasite) enters the circulation, it incubates for seven to
fourteen days and then surfaces as tickbite fever.
The symptoms generally
start out with a feeling of lassitude and illness. There are also progressive
symptoms such as body pains, a headache, light-sensitive eyes and fever with
chills.
These symptoms get worse
over a period of several hours and vomiting can occur. The headache has been
described by some sufferers as the worst they have ever had. A fine reddish
rash that joins in several places can develop within two or three days.
Painfully enlarged lymph glands also occur, especially in the area that drains
the bite site. This site takes the form of a central black hole in the skin
surrounded by an inflamed area. This site, together with the inflammation
caused by the bite, usually clinches a doctor's diagnosis. However, they can
easily be hidden by a fold of flesh or body hair; so don't get uptight if a
diligent doctor performs a thorough body search before he gives his final
verdict.
When you go to see your
doctor make sure you remember to tell him you were in a tick infested area
before you started to feel bad. If you have also been to a malarial area, it
would be wise to have tests for this disease as well.
The initial diagnosis of
tickbite fever can be confirmed by a specialized blood test.
Once the doctor
establishes that you have in fact not tickbite fever, he might initially only
prescribe medicine that will work on the symptoms of the disease - the aches
and pains, the fever and that agonizing headache.
Specific antibiotic
medication designed to treat the disease itself is 'withheld’ for 48 to 72
hours to enable the body's immune system to react and eliminate the parasite
itself.
There is a school of
thought, however, that feels the immune system has had all the chance it needs
to assert itself by the time the patient starts to feel ill, and they therefore
prescribe antibiotics immediately. This would normally be tetracycline for an
adult. Younger children would be given some other form of antibiotic such as
erythromycin, which has no effect on teeth (unlike tetracycline).
These medicines would be
taken until the fever has subsided for at least 48 hours - and some doctors
wait for five days before withdrawing the drug. Normally patients respond to
these specific treatments rather quickly and will be up and about in five to
seven days. Long-term complications are usually rare, but for about six weeks
the victim will experience fitness problems and become tired easily. This is
known as a post viral syndrome. It is not advisable to perform strenuous and
taxing exercise during the recovery period.
Although the human
immunology system responds to the infection and this response helps eradicate
the infection, it would seem that long-term immunity does not occur and that
tickbite fever can reoccur if a tick carrying the germ bites one later.
Tickbite fever is not the only infection one can pick up from ticks. The
insects can pass on diseases such as typhus and trench fever. However, cases of
these diseases from this source are fortunately rare.
If these diseases are
caught you will probably already be under medical care and the relevant
specialists can be called in time to restore your health.
Any fever that is
accompanied by bleeding should be taken seriously. If that happens, go to your
doctor as soon as possible. If you have been in the bush recently, tell the
doctor as this may help with his diagnosis.
One problem that does
occur occasionally is when a tourist on a five or six day trip presents the
symptoms of the disease halfway through the trip. If this happens, the ill
tourist must be taken to the nearest doctor. If he is too weak to walk, help
should be brought to the patient as soon as possible.
A Johannesburg doctor,
who is also a 4x4 enthusiast, told me that the patient should be dosed with
drugs to bring down the temperature and to kill the pain. He said that drugs
such as Panado and Aspro would not be at all helpful.
Because of this,
tourists should find out if the area they intend visiting is a recognized
tickbite fever area. If the route falls within one of the areas, stronger
painkiller and tetracycline or erythromycin must be carried in the first aid
kit. Should someone fall ill with tickbite fever, treatment should be started
immediately.
Should the patient be
left while others go for help, he must drink plenty of liquids as the fever
will cause sweating and the moisture lost this way will need replacing.
Tickbite fever should be treated seriously and can, especially in the very
young or the elderly, prove to be fatal if not treated properly and in time.
Prevention: The old
truism that Prevention is better than cure applies equally to tickbite fever.
There is no doubt that taking a few preventative measures before you embark on
your trip is far better than catching the disease.
Do not take drugs such
as tetracycline or erythromycin before doing on a hike in the hopes that this
will prevent tickbite fever. Medical tests have shown that they will not stop
you getting the disease.
Lf the grass is short
and the vegetation is sparse, the dancer of ticks hitching a ride on your legs
is minimal. However, if the grass is long and there are wetlands close by, you
stand a good chance of picking up ticks. And this does not only apply to the
bush, there have been a number of cases of people catching the disease from
ticks living in open ground in the middle of urban areas.
It is mainly in the
summer months that South Africans pick tip these pests that dangle from grass
and leaves. The best way - if somewhat uncomfortable in summer - of avoiding
ticks is to wear long trousers tucked into socks or boots. Although this is
reliable, another method to adopt if you insist on wearing shorts is to stop
the ticks getting on board by using an insect repellant on the legs in rings.
Spray above the socks, above and below the knees and just below the shorts and
groin area. Anti-mosquito sprays and lotions can be applied to the ankles and
legs, but ticks show a remarkable resilience to chemical deterrents.
Avoid sitting in long
grass, and at the end of the day inspect your body, especially the groin area,
for ticks.
Ticks are most numerous
and active at the beginning of the spring rains. Where cattle and game are
plentiful, so too are ticks. If you find a tick that has burrowed under the
skin, remove it carefully with a sharp object such as a knife or a needle. The
wound should then be washed with soap and water and then an antiseptic ointment
should be applied. A Povidone-type ointment is generally recommended.
If you have a bit of
time to spare, you can remove the smaller ticks that have attached themselves
to you by suffocating them with a blob of Vaseline or antiseptic ointment.
There is an argument
that if one pulls a tick off your body it will leave its head behind, which
will cause an infection. The counter-theory is that the bite would probably
have become septic anyway.
There are two main types
of ticks. There are 'hard' ticks, or tampans, known to entomologists as Ixodidae.
These are the more active kind and remain with their heads buried under the
skin for far longer periods than the second variety, the 'soft-bodied' ticks
known as Argasidae.
To avoid the bumps and
sores that normally accompany insect bites, try not to scratch. There are
preparations in pharmacies that will help ease the itch.
