Overview
Anal Fissure
An anal fissure is a small tear in the lining of the anus. It commonly causes sharp or burning pain during and after bowel movements and may produce a small amount of bright red blood on toilet paper or the surface of the stool. Anal fissures often develop when hard or large stools stretch the anal canal, although frequent diarrhea, childbirth, inflammatory bowel disease, or other conditions can also contribute. Most acute fissures improve with measures that keep stools soft and reduce strain during bowel movements.
COVID-19
COVID-19 is an illness caused by the coronavirus SARS-CoV-2. It spreads mainly when an infected person breathes out respiratory droplets and very small particles containing the virus. Illness can range from mild to severe, and some people develop complications or longer-lasting symptoms after the initial infection. Testing, vaccination, and appropriate medical care are important parts of prevention and management.

Anal Fissure
Anal fissure is usually diagnosed through the history of pain and bleeding together with examination of the anal area. A typical fissure may be visible as a small linear tear, often near the front or back of the anal opening. Examination can be uncomfortable, particularly during an acute episode, so it may be limited when pain is severe. Additional testing is generally unnecessary for a straightforward fissure. Persistent, recurrent, atypical, or multiple fissures may require further evaluation to identify inflammatory bowel disease, infection, or another underlying condition.
COVID-19
COVID-19 is diagnosed using tests that detect SARS-CoV-2 infection. Testing may be recommended when symptoms develop or after an appropriate exposure, depending on the situation. Common symptoms can include fever, cough, tiredness, sore throat, congestion, and changes in taste or smell, although symptoms vary. Healthcare providers consider symptoms, exposure history, and test results when evaluating illness.
Prevention
Anal Fissure
Keeping stools soft and easy to pass is central to preventing anal fissures. Adequate dietary fiber and fluid intake can help maintain regular bowel movements, while avoiding unnecessary straining may reduce trauma to the anal canal. People prone to constipation may benefit from medical advice about appropriate stool-softening measures. Treating persistent diarrhea or underlying bowel disease can also reduce irritation. Good toilet habits and prompt attention to recurrent anal pain or bleeding may help prevent a short-term fissure from becoming persistent.
COVID-19
COVID-19 risk can be reduced by staying up to date with recommended vaccines, improving indoor ventilation, and avoiding close contact with people known to be infected. Staying home when sick and following current public-health guidance can reduce transmission. People at higher risk of severe disease should discuss prevention and early treatment options with their healthcare provider.
Risk Factors
Anal Fissure
Risk factors for anal fissure include chronic constipation, passing hard stools, repeated straining, and frequent diarrhea. Pregnancy and childbirth can increase risk because of pressure and changes affecting the pelvic and anal region. Inflammatory bowel disease and some infections or other anorectal conditions can also predispose to fissures. Previous anal procedures may occasionally contribute. A low-fiber diet can make stools harder and increase the likelihood of trauma, particularly when combined with inadequate fluid intake.
COVID-19
The risk of severe COVID-19 increases with older age and certain underlying medical conditions. Risk can also be affected by immune-system problems and other factors that make it harder for the body to fight infection. Previous vaccination or infection can provide protection against severe disease, although protection changes over time. Exposure to an infected person increases the chance of becoming infected.
