Viral Infections
Viral infections like herpes simplex, respiratory syncytial virus (RSV), chicken pox and rotavirus are infections caused by a virus instead of a bacterium. Viral infections do not respond to antibiotics, but some specific viruses like influenza A and B can be treated with certain antiviral medications. Most commonly, treatment for viral infections includes drinking lots of fluids, getting rest, eating well and letting the illness run its course.

    If you have warts and plantar warts you should call your doctor for the following reasons.
    • Your plantar warts do not improve with treatment. In some cases, your doctor may want to perform a biopsy to rule out other possible causes of the warts.
    • Your warts do not respond to self-care and you would like your doctor to remove them.
    • You have signs of infection, including redness, pus, discharge, red streaking, fever and bleeding, especially bleeding that doesn't stop when you apply pressure.
    • Your wart causes pain.
    • Your warts are spreading.
    • You have anal and/or genital warts.
    • You have diabetes or a weakened immune system and you develop warts.
    • The wart starts to look or feel different or changes color.

    If your child has roseola, clean her skin by running a towel or sponge soaked with lukewarm water over her body.

    Roseola is yet another childhood illness that affects children by the age of two. It produces a high fever and a pink, spotty rash that spreads throughout the child's body. Although roseola may make your child irritable and fussy, the viral infection is not serious and should go away within a week.

    When a doctor diagnoses lymphadenopathy, he or she will ask you about the symptoms you're having, like sort throat, fever, location of the swollen lymph nodes, and when the swelling began. Your doctor will also ask about your exposure to certain illnesses like colds or chicken pox. Doctors will use this information to figure out a possible cause of your condition. In some cases, a lymph node biopsy might be performed to rule out certain conditions.

    Epstein-Barr virus can become latent or dormant in your body after exposure. This situation can persist for years, much like the chicken-pox virus which can persist for years in the nerve cells and then produce shingles at a later date. In the case of Epstein-Barr virus, it can re-activate or be persistent (for example Nicolas et al, Biomed J, 2014 demonstrated reactivation in immunocompetent patients following an unrelated critical illness, but also see review by Murata et al., Microbiol Immunol. 2014 Jun;58(6):307-17). EBV has been strongly associated with Chronic Fatigue Syndrome in studies from Stanford and elsewhere (see: Kogelnik et al. J Clin Virol. December 2006;37(suppl 1):S33-S38; Lerner et al. Drugs Today (Barc). 2002;38(8):549-561; Broderick et al. J Transl Med. 2012 Sep 13;10:191; Lerner et al. In Vivo. 2007;21(5):707-713). Symptoms of Chronic Fatigue Syndrome can include fatigue, increased amount of sleep, disrupted sleep, waking unrested from sleep, joint pain, flu-like symptoms, loss of interest in formerly enjoyed activities (due to insufficient energy), painful lymph nodes, muscle pain, and malaise after exertion. It is not unusual for this set of symptoms to be confused with depression according to research I have published (see: Henderson, Adv Mind Body Med. 2014 Winter;28(1):4-14).

    Tests for EBV: The only way to know for sure if an active EBV infection is the cause of fatigue is to get tested. If you have been exposed to the virus your immune system will make antibodies that the test will measure; tests measure the concentration of 6 types of EBV antibodies and the level can indicate if the infection is current or a past infection. A rising or high antibody level after at least 4 weeks of illness suggests an active infection. A positive reaction to the Monospot test indicates active mononucleosis.

    There are also molecular tests that measure EBV DNA, which can help diagnose EBV-related cancers.

    The effects of encephalitis on the body may include paralysis, poor coordination, and fatigue. Hearing problems and vision trouble may also be experienced. Serious cases of encephalitis can cause a person to suffer respiratory arrest, or to stop breathing. In some cases, encephalitis leads to coma and death.

    A Pediatrics, answered on behalf of
    Roseola is contagious and spreads through tiny drops of fluid from the nose and throat of infected people. These drops are expelled when an infected person talks, laughs, sneezes, or coughs. Other people who breathe the drops in or touch them and then touch their own noses or mouths can then also become infected.

    The viruses that cause roseola do not appear to be spread by kids while they are exhibiting symptoms of the illness. Instead, someone who has not yet developed symptoms often spreads the infection.

    To make a diagnosis, your doctor first will take a history and do a thorough physical examination.  A diagnosis of roseola is often uncertain until the fever drops and the rash appears, so the doctor may order blood or urine tests to make sure that the fever is not caused by another type of infection such as a bacterial illness with similar symptoms.  

    Recovery is quick.  Roseola usually does not require professional treatment, and when it does, most treatment is aimed at reducing the high fever. Antibiotics cannot treat roseola because a virus, not a bacterium, causes it. Your child should feel completely better by the time the rash has disappeared.

    A Pediatrics, answered on behalf of
    Roseola (roseola Infantum) is one of the common childhood rashes with fever caused by a virus.  A child with roseola typically develops a mild upper respiratory illness, followed by a high fever (often over 103° F or 39.5° C) for up to a week. During this time, the child may appear fussy or irritable and may have a decreased appetite and swollen lymph nodes (glands) in the neck.

    The high fever often ends abruptly, and at about the same time a pinkish-red flat rash appears on the trunk and spreads over the body. The rash's spots blanch (turn white) when you touch them, and individual spots may have a lighter "halo" around them. The rash usually spreads to the neck, face, arms, and legs.  Not itchy, the rash goes away within hours to a few days.

    The fast-rising fever that comes with roseola may trigger febrile seizures (convulsions caused by high fevers) in about 10% to 15% of young children.  Some children also have mild diarrhea, a cough and earache.  Children with a suppressed immune system could develop hepatitis or pneumonia.

    If you have lymphadenopathy, you may experience swollen, tender, or painful lymph nodes, especially in the head and neck. Other symptoms may include a sore throat, fever, and reddening of the skin over the nodes. Enlarged lymph nodes in other parts of your body could indicate a more serious condition like HIV or lupus.

    Children are susceptible to Epstein-Barr virus infection as soon as the mother's protective immunity wanes. When very young children are exposed they may experience mild symptoms or none at all. The symptoms of EBV infection are not unique and mimic many run-of-the-mill childhood infections that also cause sore throat, fever and swollen glands.

    Infections that occur later can produce a wide range of symptoms if any at all. It may take between 30-50 days for symptoms to appear.
