The human body is heavily fortified against attack by
disease-causing agents. From nasal hairs to stomach acid, to the 20 square feet
or so of skin that covers us, human bodies are designed to keep out microbes
that may make us ill. The system is not completely impervious, however, and at
times we all succumb to one or other of the huge variety of infectious
pathogens, such as
Despite that fact that humans have co-evolved with many
harmless bacteria, some are decidedly more sinister, including Neisseria
meningitides, Salmonella, some strains of E. Coli, and Methicillin-resistant
Staphylococcus aureus (MRSA).
Fungal infections are a more recent threat to human
health and a distinct danger to patients with a compromised immune system.
There are no vaccines to control or prevent the spread of
parasitic diseases, and many of the treatments available are ineffective or
toxic. Parasitic infections are still the leading cause of death and disease in
the tropical and subtropical world.
Viruses can only replicate inside the host’s cells, and
many have evolved to evade the defenses of the immune system, making them
difficult to treat. Due to their extremely contagious nature, viruses spread
through populations quickly, causing epidemics and pandemics. Viral infections
also cause several forms of cancer; for example, certain strains of the human
papillomavirus (HPV) lead to cervical cancer.
