Transmission Electron Micrograph (TEM) image reveal some of the nucleocapsid morphologic features displayed by the human parainfluenza virus Type-4a (HPIV-4), which like the mumps virus, is also a Paramyxoviridae family member, and a member of the genus, Rubulavirus. The parainfluenza virus is the cause of a flu-like respiratory infection in humans, very similar to, but not as severe as the flu. Once seen by a physician, a diagnosis of parainfluenza requires treatment of the symptoms, without the requisite antibiotics, which will have no direct affect upon the virus. Symptoms can include mild flu-like symptoms such as a sore throat, cough, upper and/or lower respiratory tract illness, and bronchitis. |
