Final answer:
Echoviruses can cause aseptic meningitis and gastroenteritis but are not responsible for infectious mononucleosis or Burkitt's lymphoma, which are associated with Epstein-Barr virus (EBV).
Step-by-step explanation:
The echoviruses, also known as enteric cytopathic human orphan viruses, are a group of viruses that can cause various diseases. These viruses are known to cause conditions such as aseptic meningitis and gastroenteritis. Aseptic meningitis, commonly caused by echoviruses, is an infection of the meninges (the protective membranes covering the brain and spinal cord) and is characterized by symptoms such as headache, fever, and stiff neck. Gastroenteritis, which is inflammation of the stomach and intestines, leads to symptoms such as diarrhea, vomiting, and abdominal pain.
It's important to note that other diseases you mentioned, like infectious mononucleosis and Burkitt's lymphoma, are associated with the Epstein-Barr virus (EBV), a different type of virus from the echoviruses. Epstein-Barr virus is also known as human herpesvirus 4 (HHV-4) and is the major cause of infectious mononucleosis, also known as 'mono'. Burkitt's lymphoma is a type of cancer that affects the lymphatic system and is also associated with EBV.
In summary, out of the listed conditions, echoviruses can cause aseptic meningitis and gastroenteritis, but not parotitis, mononucleosis, or Burkitt's lymphoma, as these are associated with different viruses.
