Last week the head of the World Health Organisation sounded a large alarm bell on how antibiotics may in future not work anymore, due to resistance of bacteria to the medicines.
Antibiotic resistance has been a growing problem for some time now. From time to time, there will be news reports of the outbreak of diseases, old and new, that cannot be treated because the bacteria have grown more powerful than the antibiotics used against them.
And experts have been warning about how the wrong use of antibiotics has given the bacteria the opportunity to develop resistance, enabling them to become immune to the medicines.
