Dorothy H. Crawford, Anthony J. To determine the role of sexual contact in transmission of Epstein-Barr virus EBV and occurrence of infectious mononucleosis IM , a cross-sectional study was undertaken of EBV serologic testing and histories of IM and sexual behavior among new students at Edinburgh University. Prevalence of EBV seropositivity was significantly greater among women Having a greater number of sex partners was a highly significant risk factor for EBV seropositivity. Two thirds of IM cases, but only a tenth of asymptomatic primary EBV infections, were statistically attributable to sexual intercourse. The findings suggest that EBV transmission occurs during sexual intercourse or closely associated behaviors.
Mono is a viral infection that causes symptoms like fatigue, swollen glands, and a severe sore throat. That means you can infect other people who come in contact with your saliva, so you have to be careful about kissing or sharing personal items like cups or utensils.
Mar 06, Mono is a viral infection that causes symptoms like fatigue, swollen glands, and a severe sore throat. It's hard to say exactly how long someone with mono is vizyonbarkod.com: Stephanie Watson. Sep 15, To determine the role of sexual contact in transmission of Epstein-Barr virus (EBV) and occurrence of infectious mononucleosis (IM), a cross-sectional study was undertaken of EBV serologic testing and histories of IM and sexual behavior among new students at Edinburgh vizyonbarkod.com by:
This is called the incubation period. You can pass the virus to other people through your saliva for up to three months after your symptoms subside.
Some studies have reported that you may still be contagious for up to 18 months.
EBV spreads from person to person through saliva and other bodily fluids. If you kiss a person who has the virus - or you share personal items like utensils, glasses, food, or lip balm - you can become infected. You can also catch mono if someone who is sick coughs or sneezes close to you. Teens and young adults are most likely to get sick with mono symptoms. If your symptoms worsen or persist for more than a day or two, make an appointment to see your doctor.

May 18, Epstein-Barr virus is the most common cause of mono (infectious mononucleosis). It's a relatively benign disease that causes minor symptoms such as fever, sore throat, enlarged lymph nodes in the neck, as well as fatigue. Mono usually resolves on . dating with mono and i wanna know more about mono hi, i got diagnosed with mononucleosis around two weeks ago. i was hospitalised and treated. here was how my mononucleosis went: i had swelling around my jaw area and a bad sorethroat. i then found out i had tonsilitis and there were ulcers in my throat and my throat was dead red, almost like.

Ch1 persisted in the oral cavity of N24 at each time point, and, at day 15, the strain appeared in PBLs, where it persisted through the final collection.
In contrast, Ch1 was intermittently detected in patient MO Ch1 persisted in PBLs of patient MO25 through day 15, but then the strain was not detected until it reappeared in the plasma and throat-wash samples on day Ch2 persisted in PBLs of both patients through day 33, but the strain was not detected in other compartments or at other time points. The detection of the same EBV variants in this couple provides strong evidence for transmission and indicates that multiple strains can be transmitted from a single seropositive individual.
Specific EBV strains in particular compartments In the present study, 95 PBL samples, 78 plasma samples, and 99 throat-wash samples were obtained from 30 patients with infectious mononucleosis and were analyzed.
Although particular strain variants did not appear to be restricted from a particular compartment, certain strains were detected more frequently in 1 particular compartment table 3. These data may indicate that specific strains are more abundant in certain cell types because of a biological advantage determined by the LMP1 variant or another viral gene. EBV-associated diseases that arise during immunocompromised states have been studied extensively; however, few studies have characterized EBV infection in healthy individuals.
The process of establishment and maintenance of persistent infection is also unclear.
In the present study, primary EBV infection was characterized in immunocompetent individuals who were experiencing infectious mononucleosis; multiple strains were detected in most of the patients. Their EBV strain profiles were investigated over time to monitor the exchange of virus between the oral cavity and peripheral blood during the establishment of persistent infection.
The data reveal that primary EBV infection is quite complex and involves at least 3 compartments, including the oral cavity, PBLs, and the cell-free fraction of the blood plasma, which implies the existence of another distinct, undefined compartment. The transmission of multiple strains from a healthy carrier to an EBV-negative individual was clearly demonstrated in the present study by analysis of patients MO25 and N24 table 2.
The detection of the same strains in both patients confirms that patient N24 was the likely source of virus for patient MO Similar to the infection recently described for asymptomatic carriers [ 10 ], in the present study, the patients with infectious mononucleosis demonstrated a remarkable persistence of virus in the oral cavity for several months.
EBV infection of a lymphocyte may result in a nonpermissive proliferating phenotype that subsequently undergoes class switching and maturation into a resting memory cell. The memory cell can later undergo reactivation, which may lead to renewed proliferation or to lytic infection and subsequent lysis.
In contrast, EBV infection of epithelial cells is thought to result in permissive infection. The continual detection of specific strains in the oral cavity suggests that epithelial cells play an important role during chronic lytic infection.
To determine whether the immune response provides protection from de novo infection in these patients, the EBV strain profiles were determined over time.
Nine patients had a total of 14 incidents in which a new strain that was not detected at the day of diagnosis appeared at a later time point. In 11 of the 14 incidents in which a new strain was detected, the new strain appeared for the first time in either the plasma or the B lymphocytes and, therefore, may represent an increase in relative abundance of lymphocytes infected with the particular strain. It is possible, however, that the strain was newly acquired and was present in the oral cavity between sample collections and was subsequently transferred to the peripheral blood compartment, where it was first detected.
In the other 3 incidents, a new strain was detected in the oral cavity after the day of diagnosis and was subsequently detected in the peripheral blood. These new strains may indicate a secondary infection with EBV, suggesting that the virus was able to establish a persistent infection in the presence of a developing immune response to EBV.
Previous studies have described the detection of EBV in the plasma of patients with infectious mononucleosis [ ]. The origin of the EBV detected in the plasma is unclear. Viral gene expression studies were previously performed to assess the state of infected lymphocytes in the blood, and the majority of studies concluded that lymphocytes in the blood are strictly latent.
However, some studies detected the expression of the lytic transactivator, BZLF1, and concluded that lymphocytes in the blood may also undergo a permissive infection during infectious mononucleosis [ ].
Jul 08, Although you should start feeling better in two to four weeks, the fatigue can stick around much longer. You may still feel tired a couple of months later. From: Epstein-Barr Virus (EBV) WebMD. Quick background for those of you that don't know how mono works, it's a virus, you have it forever, it takes weeks for symptoms to show, symptoms last about a month and you can be contagious from 1 month before symptoms to up to 18 months after symptoms, though usually its only a month or two but no contagiousness tests exist. Feb 01, An asymptomatic EBV carrier, patient N24, was diagnosed with infectious mononucleosis 2 years before enrollment in the present study. Patient N24 and a patient with infectious mononucleosis, MO25, had been dating for 6 months before patient MO25 developed vizyonbarkod.com by:
These data clearly demonstrate that EBV infection is dynamic in the presence of a healthy immune system. Patients with infectious mononucleosis are infected with multiple EBV strain variants, similar to the situation in immunocompromised patients. The EBV strain profiles in the oral cavity are initially distinct from the strains detected in PBLs, which can be further divided into distinct strains in the lymphocytes and the cell-free plasma.
How Long Is Mononucleosis (Mono) Contagious?
Unique strains may persist in each compartment and may eventually pass between them. Importantly, the possible acquisition of secondary infections was detected in several cases. This dynamic nature of EBV infection may be particularly important in immunocompromised individuals and may be a contributing factor to pathogenesis.
