1. Whatever the route, maternal viremia seems a likely prerequisite for transplacental infection. 2. Upon infection of the CNS, secondary viremia results and symptoms usually begin. 3. Diseases associated with this genus include : upper respiratory tract disease with viremia and fecal shedding. 4. Circulating immune complexes, overwhelming viremia , or an uncontrolled immune response may be contributing factors. 5. The vaccine significantly boosted the antibody levels and reduced the duration of post-transplantation viremia . 6. Vaccination must be done before secondary viremia takes place for the individual to avoid brain damage or death. 7. This sustained replication causes a major viremia , and leads to the development of minor influenza-like symptoms. 8. Known as viremia , the presence of a virus in the bloodstream enables it to be widely distributed throughout the body. 9. Once a human is bitten by the infected mosquito, the virus can gain entry into the bloodstream, causing viremia . 10. Attempts at vaccination against maedi-visna virus have failed to induce immunity, occasionally causing increased viremia and more severe disease.
