Imagine yourself lying in a guest house bed, in a small village, in a country rife with malaria, and you come down with a fever. You feel horrible and cannot travel to the large city so you visit the local clinic for a malaria test. The nurse asks you to roll up your sleeve so he can draw blood but you see no sterile needle in sight.
Or maybe you get a small infection in your little finger. The practitioner suggests an antibiotic injection but pulls out an unsealed hypodermic.
Or perhaps you took a tumble over the handlebars and got a small gash in your knee. You need several stitches but the health worker at the clinic pulls out an old needle and thread that looks like she removed it from her sewing machine.
Many diseases including AIDS and hepatitis are blood-born and can be transmitted by a dirty needle, an infected syringe or an unsterilized razor.
We carry some basic emergency supplies for just such occasions. They weigh practically nothing and take up little room. It is possible to purchase them at pharmacies in larger cities in most of the developing world.
In some countries it is illegal to have syringes, needles, and a scalpel or razor in your possession. You may want to get a note from your doctor or travel health clinic before taking these with you.
