Ringworm is a fungal infection. It does not have anything to do with parasitic worms or worms in general. It was only named as such because doctors used to think that ringworms were caused by some parasitic worm. The fungi feed on the keratin found on the outermost layer of the skin, hair, and nails. The fungi thrive in hot, moist, and dark environment. When you get infected by with ringworm, a circular rash is visible. The round patch of rash may be somewhat itchy and later on, the center of the patch vanishes, leaving a ring-like rash. So, how long does this rash last ? How long does ringworm last?
How long ringworm lasts depends on whether or not you are applying some form of treatment. If you don’t apply any treatment and just leave your ringworm as it is, it may take several months before it finally goes away. It may even take years before the symptoms vanish.
However, if you treat your ringworm with the right medication, the ringworm symptoms will quickly disappear. In just a few days or weeks, the rash will no longer be visible. But you should keep on applying treatment for 2 to 4 weeks to kill the fungi and to avoid getting infected again. The symptoms may disappear but that does not mean that bacteria, fungi, or virus that is causing the infection is already gone. The same goes with ringworm.
There are many different treatments for ringworm. Some are topical treatments, while others are systemic treatments. Topical treatments include creams, ointments, and everything that you apply on your skin. There are a lot of antifungal creams that work really well and within two weeks, can clear the condition. These antifungal creams are best for most parts of the body, like your feet and your groin. But there are some parts of your body that cannot be treated with creams, like your scalp and your nails. So, to penetrate these areas, it is best to use systemic treatments. Systemic treatments are oral medications and usually, these oral medications are given for a three-month course.
How long ringworm lasts are a case to case basis. In some people, a ringworm may be gone within the usual two-week period. In some cases, the ringworm infection may last longer, especially cases that are left alone, untreated. But you shouldn’t leave your ringworm untreated because they can become chronic. If the ringworm takes longer than it should be, you have to visit your doctor. He/she may prescribe you something more potent than the over-the-counter creams.
