From last week’s Confederations Cup matches, spectators were blasted from all directions by the earth-shattering noise of the vuvuzela. In addition to the health hazards of ringing ears and thundering headaches, a by-product of mindlessly blowing on this instrument is the accumulation of a huge amount of saliva. 
Tangu mechi za Kombe la Mabara, watazamaji walilipuliwa kutokea pande zote za uwanja na kelele zenye-kutikisa dunia za vuvuzela.Zaidi ya madhara ya kiafya ya masikio na maumivu ya kichwa, bidhaa nyingine itokanayo na upulizaji wa kifaa hiki ni mkusanyiko mkubwa wa mate.
