Adenovirus can also invade the lungs and infect the eyes, stomach and intestines. Rarely, these viruses sneak past the immune system and strike the liver, heart or brain. Adenovirus hijacks the inner-workings of cells, turning them into virus-producing factories.
This serves to multiply the virus and spread infection, but eventually leads to cell destruction and an intense inflammatory response. There are over 60 human serotypes of adenovirus, so while you may form immunity against one type, there are plenty more waiting to strike again. The symptoms of adenovirus depend on the site of infection. Since the upper respiratory tract is most common, kids usually present with fever, nasal congestion, cough and sore throat. Sometimes all these symptoms are present during the same illness!
Fever from adenovirus is usually short-lived, but other symptoms can last a week or more. This is because even after the virus has been defeated, the body must clean up destroyed cells and make new ones. Treatment usually involves measures to relieve the symptoms.
Doctors might recommend rest, drinking plenty of fluids, use of over-the-counter medicines to manage fever or discomfort, or use of a cool-mist humidifier. Ill persons should see a doctor if fever continues for more than a few days, symptoms worsen, breathing problems occur, or not enough fluids are being taken.
Those with serious illness or weak immune systems might need additional treatment or hospitalization. Antibiotics are not used to treat adenovirus infections. There is no vaccine generally available to prevent adenovirus infection. Good health habits can help prevent adenovirus infection. These include covering the mouth and nose when coughing or sneezing; washing hands often with soap and water; avoiding touching the eyes, nose or mouth; avoiding sharing cups and eating utensils; staying home from work, school, and errands if sick; and avoiding close contact with people who are sick.
Keeping adequate levels of chlorine in swimming pools is important to prevent outbreaks of conjunctivitis caused by adenovirus. Eye infections: Pinkeye conjunctivitis is a mild inflammation of the membranes that cover the eye and inner surfaces of the eyelids.
Symptoms include red eyes, discharge, tearing, and the feeling that there's something in the eye. Pharyngoconjunctival fever causes very red eyes, a sore throat, fever, runny nose, and swollen glands. Keratoconjunctivitis is a more severe eye infection that involves both the conjunctiva and cornea the transparent front part of the eye.
It causes red eyes, photophobia sensitivity to light , blurry vision, tearing, and pain. Nervous system infections: Meningitis and encephalitis can sometimes happen due to adenovirus infection. Symptoms include fever, headache, nausea and vomiting, stiff neck, and confusion. Is Adenovirus Contagious? Symptoms usually start 2 days to 2 weeks after contact with adenovirus. How Are Adenovirus Infections Diagnosed?
How Are Adenovirus Infections Treated? Can Adenovirus Infections Be Prevented? To help prevent the spread of adenovirus infections, parents and other caregivers should: make sure kids and caregivers wash their hands well and often keep shared surfaces such as countertops and toys clean keep kids with infections out of group settings until symptoms are gone teach kids to sneeze and cough into shirtsleeves or tissues — not their hands When Should I Call the Doctor?
