Human enterovirus B is a type of enterovirus that primarily infects humans and belongs to the Picornaviridae family. It is a non-enveloped, small, positive-sense single-stranded RNA virus. Enterovirus B is capable of causing a wide range of illnesses, including mild respiratory infections, acute febrile illnesses, and more severe conditions such as meningitis, encephalitis, and myocarditis.
This virus is transmitted through contact with respiratory secretions, fecal-oral route, or contact with infected surfaces. It primarily affects children but can also be found in adults. Enterovirus B can spread rapidly in crowded areas, such as childcare centers and schools.
Symptoms of Human enterovirus B infection vary depending on the specific strain and affected organ system. Some individuals may experience mild symptoms similar to a common cold or flu, including fever, cough, sore throat, runny nose, and muscle aches. In more severe cases, the infection can lead to neurological symptoms such as headache, meningitis (inflammation of the membranes surrounding the brain and spinal cord), and encephalitis (inflammation of the brain), potentially causing seizures or paralysis. Cardiac complications, including myocarditis (inflammation of the heart muscle), may also occur, leading to chest pain, heart failure, or arrhythmias.
Treatment for Human enterovirus B mainly focuses on managing the symptoms. Bed rest, plenty of fluids, and over-the-counter pain relievers may be recommended to relieve discomfort. In severe cases, hospitalization might be required for close monitoring and supportive care.
Prevention is crucial in controlling the spread of Human enterovirus B. Regular handwashing, covering the mouth and nose when coughing or sneez
