Immunodeficiency-associated Burkitt lymphoma is usually associated with HIV infection, but can also occur in the setting of post-transplant patients.Burkitt lymphoma is commonly associated with the infection of B cell lymphocytes with the EBV and in these cases is considered to be one form of the Epstein–Barr virus-associated lymphoproliferative diseases. The endemic variant of Burkitt lymphoma is in almost all cases associated with EBV infection. The fact that some Burkitt lymphoma cases do not involve EBV allows that many cases of the disease are not caused and/or promoted by EBV, i.e. the virus may be an innocent passenger virus in these cases. However, the almost ubiquitous presence of the virus in the endemic variant of Burkitt lymphoma suggests that it contributes to the development and/or progression of this variant. The mutational landscape in Burkitt lymphoma has recently been found to differ between tumors with and without EBV infection, further strengthening the role of the virus in disease origin. Pathophysiology
Genetics
All types of Burkitt lymphoma are characterized by dysregulation of the c-myc gene by one of three chromosomal translocations. This gene is found at 8q24. The most common variant is t(8;14)(q24;q32), which accounts for about 85% of cases. This involves c-myc and IGH@. A variant of this, a three-way translocation, t(8;14;18), has also been identified. A rare variant is at t(2;8)(p12;q24). This involves IGK@ and c-myc. Another rare variant is t(8;22)(q24;q11).
Types of subclinical infections
The following pathogens (together with their symptomatic illnesses) are known to be carried asymptomatically, often in a large percentage of the potential host population:

Host tolerance
Fever and sickness behavior and other signs of infection are often taken to be due to them. However, they are evolved physiological and behavioral responses of the host to clear itself of the infection. Instead of incurring the costs of deploying these evolved responses to infections, the body opts to tolerate an infection  as an alternative to seeking to control or remove the infecting pathogen.Subclinical infections are important since they allow infections to spread from a reserve of carriers. They also can cause clinical problems unrelated to the direct issue of infection. For example, in the case of  urinary tract infections in women, this infection may cause preterm delivery if the person becomes pregnant without proper treatment. See also
