Members of the health professions have had access to antibiotics for the last seventy years and medical ​advances are very dependent on them working effectively. However, there have been no new classes of antibiotics released in the last twenty years. There have been modifications to existing antibiotic classes and there is still a wide array of antibiotics available at this present time. But these numbers are reducing every year as bacteria become resistant. At some point their effectiveness may stop and we could be left without any antibiotics. Without antibiotic cover, the threat of infection and potential life threatening sepsis is high, especially when the patient is immunocompromised. Even simple infections can become complicated and result in cellulitis, loss of limb, loss of tissue, and sepsis if antibiotic treatment is not instigated at the right time.
