What is the incubation period for infectious mononucleosis?

What is the incubation period for infectious mononucleosis?

People who have mono can be contagious from the time they first become infected. But they may not know that they have the virus. It takes a while for mono symptoms (like tiredness, fever, muscle aches, headache, or sore throat) to show up — about 1–2 months, in fact. This is called the incubation period.

How long is the incubation period of Epstein Barr virus and what type of cells does it preferentially targets?

During the 6-week incubation period of primary EBV infection, viral replication is first detected in the oral cavity. There EBV infects both B cells and tonsillar epithelial cells.

Why does mono have such a long incubation period?

Risk factors The EBV virus, which causes mono, is most often spread through saliva. Many people contract the virus during childhood and never notice any symptoms. Once the virus enters the body, it stays there forever, and it can occasionally reactivate at a later time.

How long do the signs of active infectious mononucleosis usually persist?

The signs and symptoms of mono typically last for 1 to 2 months. The incubation period may be shorter in young children. Some symptoms, like sore throat and fever, typically lessen after 1 or 2 weeks. Other symptoms such as swollen lymph nodes, fatigue, and an enlarged spleen may last a few weeks longer.

How do I know if my mono is still contagious?

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….When to see your doctor

• fatigue.
• a sore throat.
• fever.
• swollen lymph nodes in your neck.
• headache.
• muscle aches.

Can you only get mono once?

Most people who have mono (infectious mononucleosis) will have it only once. But rarely, mononucleosis symptoms may recur months or even years later. Most cases of mononucleosis are caused by infection with the Epstein-Barr virus (EBV).

Can you test positive for mono during incubation period?

EBV antibody test This blood test looks for EBV-specific antibodies. This test can detect mono as early as the first week you have symptoms, but it takes longer to get the results.

Can you get mono from someone who had it years ago?

The virus can show up in a person’s saliva from time to time, even if it doesn’t make that person feel sick with mono again. In theory, there is a very small chance that you can transmit EBV to someone else at any given point in time, even if you feel OK.

Can you get mononucleosis more than once?

Can you get mono from giving a BJ?

It’s quite possible that infection could be passed on during oral sex. Mono, known to doctors as infectious mononucleosis, is usually caused by infection with the Epstein-Barr virus.

What is the incubation period of infectious mononucleosis?

The incubation period of infectious mononucleosis is approximately 6 weeks. Hoagland’s clinical records suggested an incubation period of 32–49 days based on the dates of kissing episodes until the onset of infectious mononucleosis (Hoagland 1955).

What are the symptoms of mononucleosis in older adults?

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.

What is a differential diagnosis of infectious mononucleosis?

Differential diagnosis. About 10% of people who present a clinical picture of infectious mononucleosis do not have an acute Epstein–Barr-virus infection. A differential diagnosis of acute infectious mononucleosis needs to take into consideration acute cytomegalovirus infection and Toxoplasma gondii infections.

What is secondary cold agglutinin disease in mononucleosis?

Mononucleosis is sometimes accompanied by secondary cold agglutinin disease, an autoimmune disease in which abnormal circulating antibodies directed against red blood cells can lead to a form of autoimmune hemolytic anemia. The cold agglutinin detected is of anti-i specificity.
