Besides
medical and first aid
supplies, there are other items which
are very often required by global
travellers, these include:-
Most of
these items can be obtained on-line
from Nomad Travel, MASTA or from
Up & Under of Cardiff - see
the links at the bottom the page.
Insect
Repellents
Chemical
repellents are the best and perhaps
the only suitable personal protection
against outdoor biting insects.
Repellents
act by interfering with the sense
organs with which insects locate their
victims.
Most
of the commercially available insect
repellents contain diethyl toluamide
(DEET), or dimethylphthalate (DMP).
These
preparations come as lotions, sticks,
gels, creams, or in aerosol cans or
pump-action dispensers.
DEET
is apparently effective against all
free-flying biting insects.
DEET
has been used without harm by millions
of people. However, there have been
occasional reports of serious reactions
in a few individuals. Anyone who suspects
an adverse reaction to DEET should
stop using it immediately and seek
medical advice.
The chances
of an adverse skin reaction are reduced
if DEET is impregnated into clothing
rather than applied directly to the
skin.
When
applied to the skin, DEET remains
effective for only a few hours. However,
when impregnated into cotton (not
synthetic) material it remains effective
for several weeks.
When sitting down out of doors, most
mosquito bites occur on the ankles
or feet. Cotton ankle bands impregnated
with DEET have been found to give
up to 85% reduction in bites by several
species of mosquitos.
MozzyOff
is a 100% natural midge and mosquito
repellent and an alternative to DEET
for those who cannot tolerate it.
Made
from plant oils, MozzyOff offers you
up to six hours protection from biting
insects such as midges and mosquitoes,
black fly and gnats. It's water resistant
and unlike chemical based products,
MozzyOff repellent will not harm synthetic
materials. MozzyOff is also biodegradable
and the packaging is recycled and
recyclable so its good news for the
environment too.
MozzyOff
is kind to your skin and its inherent
soothing properties mean that it will
relieve the itch of previous bites
and hopefully stop you getting bitten
again. For further information see
www.mozzyoff.com
Another
option is to wear insect repellent,
impregnated clothes. In this case
the repellent Permethrin is
used and is tightly bonded to the
fibres of the garment. When insects
are exposed to this repellent their
neurons are agitated, rendering them
unable to coordinate voluntary muscles,
and thus unable to attack. Unlike
traditional insect repellents, Insect
Repellent Clothing puts the insect
repellent on the clothes you wear,
not on your skin.
Traditional repellents usually last
for several hours but with permethrin-based
insect repellent clothing, the insect
repellent is IN YOUR CLOTHING, not
on your skin and keeps working as
long as youre wearing the shirt,
trousers, hat or other garment.
Permethrin has been shown to be effective
the entire time the impregnated clothing
is worn and is effective in repelling
mosquitoes, ticks, ants, flies, chiggers
and no-see-ums.

Mosquito Nets
The
use of a mosquito net is strongly
recommended wherever there is any
risk of bites from mosquitoes that
bite at night.
It is
well worth buying a good quality net,
because any slippage of the weave
would allow mosquitoes to enter. Any
tears should be repaired or blocked
with cotton wool and the net should
be tucked in carefully under the mattress.
The net
should be checked after getting into
bed, using an electric torch to make
sure that no gaps are left. Care should
also be taken not to sleep with any
part of the body touching the net
since mosquitoes can feed through
nets.
Increased
security can be achieved by impregnating
the net with permethrin which is very
effective in killing or repelling
mosquitoes which come into contact
with it.
Many
hotels in the tropics provide mosquito
nets. If in doubt it would be worth
taking your own.
Another
useful measure is to spray your room
(or tent) with an insecticide aerosol
spray after closing the doors and
any windows. This will kill any insects
that entered the room earlier but
not any that enter later. For this
reason all doors and windows should
be kept closed during the night.
Sun
Screens & Sun Blocks
Sunlight
contains Ultra Violet light which
can be further categorised as UVA
and UVB.
Exposure
to UVB increases the risk of basal
cell carcinoma and squamous cell carcinoma,
two forms of non-melanoma skin cancer.
It is also responsible for sunburn.
Exposure to UVA causes skin ageing
and there's a high level of concern
that UVA increases the risk of malignant
melanoma, the most dangerous form
of skin cancer. In contrast to UVB,
UVA does not cause sunburn.
Sunscreen
sun protection factors (SPF) are measured
by timing how long skin covered with
sunscreen takes to burn compared to
uncovered skin. For example, SPF 15
means it will take 15 times longer
to burn when wearing the sunscreen.
Although they found that the sunscreen
lotions did protect well against UVB
rays, the UVA protection was less
than satisfactory.
Because SPF factors only look at burning
times, they only apply to UVB rays.
In
the UK the number of cases of skin
cancer are said to be rising faster
each year than for any other form
of cancer. Part of the reason is thought
to be due to our changing lifestyles,
for example more people are sunbathing
and taking more holidays in sunnier
climates, increasing their exposure
to harmful UV rays.
Part
of the Government's safe sun message
advises people to use protective sunscreen
but, according to new research, while
useful for protecting against UVB
rays, lotions are less protective
against harmful UVA. What's more,
it's possible that people might be
staying out in the sun longer because
they think their skin is being protected,
actually increasing their exposure
to UVA.
It
is hoped that future sunscreens will
include better protection against
UVA.
Currently
there are two types of product used
for sun protection:-
Absorbents
which work by screening out the sun's
rays by a factor which is displayed
on the container. They come in various
forms e.g. lotions, oils, creams,
etc.
Reflectants
which are creams usually white and
based on zinc oxide which
totally block out the sun by forming
a physical barrier.
Both forms can be purchased from a
number of outlets e.g. Pharmacies,
sports shops, outdoor equipment suppliers,
supermarkets, etc.
Good sun protection methods include
staying in the shade during the peak
sun strength times, covering up, wearing
sunglasses and a wide brimmed hat
and using an SPF 15 or higher sunscreen.

Exposure to the Sun
Water
Purification
When
you travel abroad you should always
assume that the water is unsafe to
drink unless you know otherwise. Even
in European hotels and holiday resorts
it is a good policy not to drink the
local tap water.
Safe
Water for International Travelers
(SWIT)
- is an independent organization that
provides the best available information
about water safety around the world.
Information is gathered from the most
important and trustworthy sources.
They have a web site which categorizes
the state of the drinking water in
any given country.
There
are many diseases that can be spread
by contaminated drinking water including
typhoid, cholera, hepatitis A, dysentery
and several diarrhoeas.
Nowadays
safe drinking water is available world-wide
in sealed plastic bottles but you
should always make sure that the seal
is in tact when you receive a bottle.
If not, do not accept it, it could
have been refilled from another source.
In very remote areas where drinking
the local water is the only option
available, some form of purification
may be necessary.
Water purification entails disinfection
and removal of suspended particles.
There are three options available:-
| Boiling,
Iodination & Filtration |
Quite
often it is necessary to employ more
than one method. When this is the
case always filter water before boiling
it and boil water before treating
with iodine, but always wait for boiled
water to cool down before adding the
iodine.

Each
year 10 million international
travellers or expatriates, suffer
severe waterborne diseases from
ingestion of contaminated water
or food while travelling or
staying abroad.
Worldwide, unsafe water is a
major problem. One billion people
do not have access to safe water.
It is estimated that diarrhoeal
diseases that result from contaminated
water kill about 2 million children
and cause about 900 million
episodes of illness each year.
However, international travellers
should not become hysterical
about avoiding all water whilst
travelling abroad. Most of the
general information sites for
travellers recommend to avoid
drinking water anywhere abroad.
But to avoid water where it
is safe, could be as annoying,
as it is dangerous to drink
it where it is not safe.
Information is now available
on the purity of drinking water
worldwide. For a list of all
the countries and the quality
of their drinking water:

The
simplest and most effective method
of water purification is boiling for
five minutes (longer at altitude).
When cooled, the water should be kept
in a clean sealable container to avoid
recontamination.
Chemical purification using iodine
is another option but care must be
taken not to take too much. Iodine
should only be used for short periods
and people with thyroid problems should
consult with their doctor before using
it.
Iodine
is a very effective disinfectant and
Iodination is preferable to chlorination
since iodine is effective against
waterborne pathogens, Giardia and
other resistant organisms like amoebic
cysts which are resistant to chlorine.
It can also be used to purify water
for washing and cooking.
It is available as tablets, crystals
or tincture (drops). You should always
follow the usage instructions on the
container.
After
adding the iodine, allow the water
to stand for at least thirty minutes
before drinking.
The third method is by filtration
which is essential when the water
is turbid or there is a high degree
of suspended matter.
The filter will clarify the turbid
water by removing silt, algae and
other suspended matter. Suspended
organic particles also interfere with
the process of chemical disinfection.
Units used to filter water should
be dependable, easily maintained and
give some indication of when their
useful life has expired.
Filters remove impurities from the
water by mechanical straining and
some form of further purification
is almost always necessary.
This is because filters work by drawing
water through a microporous element
such as as a ceramic filter with a
pore size of 0.2 microns.
This will remove all pathogenic bacteria,
cysts, protozoa and helminths but
not viruses that are much smaller
than the 0.2 microns, and since hepatitis
A and several forms of diarrhoea are
caused by viruses further treatment
is necessary.
Beware
of extravagant claims made by manufacturers
as to the effectiveness of water filters
without producing convincing evidence
of their claims. Remember, the life
of a filter is greatly lowered when
used with highly turbid water and
the filter should be checked periodically
for cracks and leaks.
There are several filters available
commercially some of which are quite
expensive so you should seek specialist
advice before purchasing one.
N.B. Drinking water that has been
purified by filtration alone should
only be considered if you are happy
about the quality of the source but
filtered water should always be boiled
or disinfected before giving to children
and babies.
For
those who find themselves in places
where the water is doubtful or even
dangerous to drink, bw technologies,
the water quality specialists have
a range of safe, effective water filtration
systems; The aquapure traveller, survivor4i
and inline filters are unique, self-contained,
convenient water purification systems
designed to fit into a bottle or hydration
system.
Adventure
holidays now make up a large proportion
of the total holidays bought in the
UK. Adventure holidays do involve
a certain amount of self sufficiency,
even on a totally managed holiday.
Imagine never having to worry about
where your water comes from or buying
bottle water again. Some bottled waters
in less developed countries are no
more than local tap water put into
branded self-sealing bottles.
One
pure hydration filter can save as
much as 700 plastic bottles from being
dumped.
In fact, there are places on the planet
that do not allow you to use disposable
plastic bottles. The Inca trail is
just one of them.
