A newly emerging “untreatable” mystery virus that is being described as stronger than Covid is now spreading across several parts of the world, with experts warning that even common disinfectants may not be effective against it. Known as adenovirus, the infection causes symptoms similar to a severe bout of flu, such as shortness of breath, a runny nose, and a sore throat. What sets it apart, however, is the limited treatment available. In most cases, people who contract the virus have no option but to manage symptoms and allow the illness to pass on its own. The good news is that adenovirus infections are usually mild. That said, much like Covid or seasonal flu, the risk rises for people with weakened immune systems, who may experience more serious complications, according to a report by The Mirror.Also Read: British Man Compares Breathing In Delhi To Smoking 18 Cigarettes Jefferson Health’s medical director of infection prevention and control, Eric Sachinwalla, has cautioned that unlike more familiar viral infections, there is very little doctors can do to actively treat adenovirus.What Is Adenovirus?Adenoviruses belong to a broad family of common viruses that can affect multiple parts of the body, including the airways and lungs, eyes, digestive system, urinary tract, and even the nervous system. They are a frequent cause of fever, cough, sore throat, diarrhoea, and conjunctivitis. Most infections tend to be mild and clear up on their own within a few days. However, health experts are now noting a rapid rise in cases, with the virus spreading quickly and leaving large numbers of people unwell.The virus is particularly contagious because it is tougher than many others. Routine cleaning with soap and water or standard disinfectants may not be enough to eliminate it, allowing it to survive longer in the environment. This is why outbreaks are often seen in places such as day-care centres and military barracks, where close contact is common. Adenovirus spreads through respiratory droplets, can be passed through stool, and can linger on contaminated surfaces for extended periods, as per Mirror.Adenovirus SymptomsSymptoms of adenovirus infection can vary widely. Common signs include shortness of breath, a runny nose, and a sore throat. Some people may also develop diarrhoea or pink eye. The wide range of symptoms is partly due to the fact that there are more than 60 known strains of the virus.How Is Adenovirus Different From Covid And Flu?Adenoviruses, like coronaviruses, spread from person to person and can trigger similar respiratory symptoms. However, they belong to entirely different virus families and behave differently. One key difference is resistance. Coronaviruses are more easily destroyed by disinfectants, while adenoviruses are harder to kill, which allows them to spread more easily than Covid or flu.For otherwise healthy individuals who feel unwell but do not have severe symptoms such as high fever or breathing difficulty, recovery usually happens at home with basic supportive care. Medical attention is more important for people with weakened immunity, parents of very young infants, or those with existing conditions like heart or lung disease. If symptoms appear, experts advise against walking straight into a clinic. Calling ahead is safer, as doctors may recommend a telehealth consultation if the illness seems highly contagious.Is Adenovirus Untreatable?Most adenovirus infections are mild and resolve without medical treatment. However, if symptoms linger or worsen, there is often little doctors can do beyond monitoring and symptom relief, as the virus largely needs to run its course. Following basic hygiene measures, such as washing hands regularly and cleaning frequently touched surfaces, remains one of the most effective ways to reduce the risk of infection.
