In some countries you can catch infections that are transmissible via blood without noticing. In most cases you will not notice such an infection yourself, but when you donate blood, the recipient of the blood can become ill.
Temporarily stop giving blood
You can catch infections closer to home than you might expect. For example, you can contract the West Nile virus in Greece or Italy. Have you been abroad and do you want to know whether you can donate blood? then you can do the online donor test.
Drastic measure?
It may seem like a drastic measure, but to keep blood transfusions safe, it's a safe bet.
