An infection is the detrimental colonization of a host organism by a foreign species. In an infection, the infecting organism seeks to utilize the host's resources to multiply. The infecting organism, or pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb, and even death.

The host's response to infection is inflammation. Colloquially, a pathogen is usually considered a microscopic organism though the definition is broader, including feces, parasites, fungi, viruses, prions, and viroids. A symbiosis between parasite and host, whereby the relationship is beneficial for the former but detrimental to the latter, is characterised as parasitism. The branch of medicine that focuses on infections and pathogens is infectious disease. A secondary infection is an infection that occurs during or following treatment of another already existing primary infection.

Reactions present with a variety of infectious disorders, often occurring in response to an inflammatory tinea of the feet, resulting in an eczematous dermatitis. Id reactions are frequently unresponsive to corticosteroid therapy, but clear when the focus of infection or infestation is treated.

C. Antiviral
Antiviral drugs are a class of medication used specifically for treating viral infections. Like antibiotics, specific antivirals are used for specific viruses. Antiviral drugs are one class of antimicrobials, a larger group which also includes antibiotic, antifungal and antiparasitic drugs. They are relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from viricides, which actively deactivate virus particles outside the body. Examples of Antiviral drugs are as follows:

Brand Names	Generic Prescription (Rx) Drugs
zovirox	acyclovir
rebetol	ribavirin

D. Anti Viral-HIV:
Most of the antivirals now available are designed to help deal with HIV; herpes viruses, best known for causing cold sores and genital herpes, but actually causing a wide range of diseases; the hepatitis B and C viruses, which can cause liver cancer; and influenza A and B viruses.
Example of Anti Viral- HIV are as follows:

Brand Names	Generic Prescription (Rx) Drugs

E. Antifungal drug
An antifungal drug is medication used to treat fungal infections such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others. Such drugs are usually obtained by a doctor's Prescription (Rx) or purchased over-the-counter. Examples of Antifungal drug are as follows:

Brand Names	Generic Prescription (Rx) Drugs

F. Antituberculosis Drugs
The standard "short" course treatment for tuberculosis, if it is active, is isoniazid, rifampicin, pyrazinamide, and ethambutol for two months, then isoniazid and rifampicin alone for a further four months. The patient is considered cured at six months. For latent tuberculosis, the standard treatment is six to nine months of isoniazid alone.
If the organism is known to be fully sensitive, then treatment is with isoniazid, rifampicin, and pyrazinamide for two months, followed by isoniazid and rifampicin for four months. Ethambutol need not be used. Examples of Antituberculosis Drugs are as follows:

Brand Names	Generic Prescription (Rx) Drugs
myambutol	ethambutol hydrochloride

G. Drugs for Vaginal and Uretheral Conditions
Drugs for Vaginal and Uretheral Conditions are used to treat infections such as infections with Candida albicans, Bactarial vaginosis, Trichmoniasis, urinary bladder infection, urinary tract infction, urethritisetc. Examples of Drugs for Vaginal and Uretheral Conditions are as follows:

Brand Names	Generic Prescription (Rx) Drugs

H. Antimalarial drug
Antimalarial drugs are designed to prevent or cure malaria. Some antimalarial agents, particularly chloroquine and hydroxychloroquine, are also used in the treatment of rheumatoid arthritis and lupus associated arthritis.
