Why does shingles not cross the midline?

This is because each nerve runs from one side of the spine in the back to the middle of the front of the body and does not cross this midline. This is important when considering the rash of shingles. The rash will occur in a dermatome and will not cross the midline of the body either in the front or the back.

Can shingles pain cross the midline?

Shingles rashes tend to form along one or two dermatomes on one side of your body. Their location depends on which nerve the virus spreads from. The rash doesn’t cross the midline of your body because each spinal nerve supplies sensory information only for the left or right side of your body.

Does disseminated shingles cross the midline?

The rash does not usually cross the body’s midline. Less commonly, the rash can be more widespread and affect three or more dermatomes. This condition is called disseminated zoster. This generally occurs only in people with compromised or suppressed immune systems.

Can varicella zoster virus cross the placental barrier?

Yes. The varicella zoster virus can be transmitted from a mother to her unborn baby, since it can cross the placental barrier. The probability of an infected mother transmitting the virus to a fetus varies from 5–25 percent depending on the trimester of pregnancy.

How is disseminated shingles diagnosed?

The ideal samples are swabs of unroofed vesicular lesions and scabs from crusted lesions; you may also detect viral DNA in saliva during acute disease, but salvia samples are less reliable for herpes zoster than they are for varicella. Biopsy samples are also useful test samples in cases of disseminated disease.

How do you know if shingles is disseminated?

Whether disseminated or localized, the early symptoms of shingles include headache, flu-like symptoms minus a fever, and sensitivity to light. A red and blistering rash develops a few days after the onset of these symptoms and may be accompanied by itching, tingling, or extreme pain in the area surrounding it.

Is shingles unilateral or bilateral?

Attacks often recur with vesicle groups spread bilaterally, whereas shingles is usually unilateral, affecting one or adjacent dermatomes. It rarely recurs unless the patient is immunocompromised.

Can shingles affect both sides?

Occasionally, two or three nerves next to each other are affected. Very rarely, shingles can cause more widespread infection, or can affect both sides of the body, but this is usually only in people with a weakened immune system.

How serious is disseminated shingles?

Patients in whom zoster has disseminated must be observed carefully for the development of pneumonitis and encephalitis, which can be life-threatening.

What is considered disseminated shingles?

The condition is also known as disseminated cutaneous HZ (DCHZ). It is commonly defined as more than 20 skin lesions beyond the primary or adjacent dermatomes. DCHZ generally occurs only in individuals with compromised or suppressed immune systems.
