This may develop into systemic EBV-positive T cell lymphoma. Older adults
Infectious mononucleosis mainly affects younger adults. When older adults do catch the disease, they less often have characteristic signs and symptoms such as the sore throat and lymphadenopathy. Instead, they may primarily experience prolonged fever, fatigue, malaise and body pains. They are more likely to have liver enlargement and jaundice. People over 40 years of age are more likely to develop serious illness. (See Prognosis.) Incubation period
The exact length of time between infection and symptoms is unclear. A review of the literature made an estimate of 33–49 days. In adolescents and young adults, symptoms are thought to appear around 4–6 weeks after initial infection. Onset is often gradual, though it can be abrupt. The main symptoms may be preceded by 1–2 weeks of fatigue, feeling unwell and body aches. Cause
Epstein–Barr virus
About 90% of cases of infectious mononucleosis are caused by the Epstein–Barr virus, a member of the Herpesviridae family of DNA viruses. It is one of the most commonly found viruses throughout the world. Contrary to common belief, the Epstein–Barr virus is not highly contagious. It can only be contracted through direct contact with an infected persons saliva, such as through kissing or sharing toothbrushes. About 95% of the population has been exposed to this virus by the age of 40, but only 15–20% of teenagers and about 40% of exposed adults actually become infected. Cytomegalovirus
About 5% to 7% of cases of infectious mononucleosis is caused by human cytomegalovirus (CMV), another type of herpes virus.
It is also highly soluble in xylene, oleic acid, acetone, diacetone alcohol, methanol, isopropanol,
2-butanol, methyl acetate, ethyl acetate, furfurol, and vegetable oils.The ester groups are easily cleaved under basic conditions, but are stable against acids. Synthesis
Sodium dioctyl sulfosuccinate can be obtained by treating  dioctyl maleate with sodium bisulfite. The bisulfite anion adds to the double bond:

−CH=CH− + HSO−3 → −CH(−SO−3)−CH2−

Toxicity
Ingestion may cause the side effects described above, such as diarrhea, intestinal bloating, and occasionally cramping pains. Dioctyl sodium sulfosuccinate is not known to be carcinogenic, mutagenic, or teratogenic. Marine species
Dioctyl sodium sulfosuccinate is of low toxicity for crustaceans such as the hermit crab Clibanarius erythropus and the shrimp Crangon crangon. Toxicity for molluscs varies widely, with 48-hour LD50 found between 5 mg/L for the common limpet and 100 mg/L for the common periwinkle. Various species of phytoplankton have an LD50 around 8 mg/L. In a 2010 study, dioctyl sodium sulfosuccinate exhibited higher toxicity against bacteria (Vibrio fischeri, Anabaena sp.) and algae (Pseudokirchneriella subcapitata) than did a number of fluorinated surfactants (PFOS, PFOA, or PFBS). Measuring bioluminescence inhibition of the bacteria and growth inhibition of the algae, the LD50 were in the range of 43–75 mg/L. Combinations of the fluorinated compounds with dioctyl sodium sulfosuccinate showed mid to highly synergistic effects in most settings, meaning that such combinations are significantly more toxic than the individual substances. Freshwater species
The substance is highly toxic for rainbow trout with a median lethal concentration (LC50) of 0.56 mg/L after 48 hours for the pure substance.
