Presentation
Approximately two-thirds of neonates with disseminated or CNS disease have skin lesions, but other symptoms may be present before these lesions can be seen. When skin lesions are not present, it can be challenging to diagnose neonatal HSV infection. [ncbi.nlm.nih.gov]
Neonatal CNS HSV disease often presents in the second to third week of life, although earlier presentations can occur. [med.cmu.ac.th]
CT may be negative in the early course of the disease in advanced stages may present with extensive areas of parenchymal hypoattenuation, predominantly in the white matter, as a result of edema or necrosis 3 enhancement usually presents in a gyriform [radiopaedia.org]
Symptoms mother presents with multiple, very painful, vesicular, genital ulcers infected infant presents with vesicles seizures respiratory distress meningitis encephalitis impaired neurologic development Physical exam primary herpes infection generally [medbullets.com]
Children with disease caused by HSV infection present in 1 of the 3 fashions. Disease can be localized to the skin, eye and mouth, occurring in approximately 45% of newborns. These babies present at 7–11 days of life on average. [journals.lww.com]
Entire Body System
- Fever
Factors not associated with neonatal HSV infection were fever, total peripheral white blood cell count, and red blood cells in the CSF. [journals.lww.com]
The affected person may feel well or suffer from fever, pain and have enlarged local lymph nodes. [dermnetnz.org]
Generalized symptoms such as fever and malaise may develop, and lymph nodes in the groin may enlarge. Lesions may persist in this stage for a week or more, and complete healing may take four to six weeks. [britannica.com]
Less Common Symptoms In general, herpes simplex infections cause sporadic recurrences of sores, often with a preceding trigger, such as a cold or a fever—and sometimes without any trigger at all. [verywell.com]
- Pain
Enlarged and painful lymph glands : Glands in the neck, under the arms, or in the groin can become enlarged or painful when you have an active herpes infection. [verywell.com]
Genital herpes (herpes genitalis) Pathogen : HSV-2, HSV-1 (less common) Incubation period : 2–7 days Clinical findings Most patients are asymptomatic Genitals: redness, swelling, tingling, pain, pruritus Possibly unusual vaginal discharge Painful lymphadenopathy [amboss.com]
If you experience symptoms of genital herpes, they may include: Pain or itching. You may experience pain and tenderness in your genital area until the infection clears. Small red bumps or tiny white blisters. [mayoclinic.org]
Anesthetic mouthwashes or pain medication may also be given to reduce pain. If your child is unable to eat or drink because of mouth sores, he or she is at risk of becoming dehydrated. [skinsight.com]
The first episode of herpes can cause considerable pain and distress. [betterhealth.vic.gov.au]
- Recurrent Infection
It is also frequent during the first year following primary infection, the week preceding and following recurrent infection, and in women having more than 12 recurrent infections per year. 5 Symptomatic, confusing diagnoses must be ruled out first, including [dermquest.com]
In most cases of recurrent infection, topical and/or symptomatic treatment is sufficient. [amboss.com]
[…] is higher with primary or non primary infections of the mother and less with recurrent infections. • Maternal antibody status:- risk of transmission is higher with primary infection and less with reactivation. • Type of HSV:- studies have shown an higher [slideshare.net]
The risk of vertical transmission is about 40% to 50% for primary infections and about 5% for recurrent infections. 5 The prevalence of HSV-2 antibodies increases with age. [nature.com]
Respiratoric
- Respiratory Distress
Inclusion of the newly appreciated features of maternal fever, respiratory distress, and thrombocytopenia might improve the detection of neonatal HSV infection. [journals.lww.com]
In addition to respiratory distress, physical examination revealed marked general erythroderma without vesicles, especially on the face and thorax (figure 1). [fn.bmj.com]
It is usually observed when the infant is 5–9 days old; signs include irritability, seizures, respiratory distress, jaundice, bleeding diatheses, shock, and often vesicular exanthema ( 3, 4 ). [wwwnc.cdc.gov]
The infant had mild respiratory distress at the time of birth but otherwise appeared normal. On day 3 of birth, the child presented with classical symptoms of HSV. [jcnonweb.com]

Gastrointestinal
- Nausea
The most common side effects are nausea, headache, and abdominal pain. [stlukes-stl.com]
- Vomiting
Like encephalitis, meningitis symptoms include headache, fever, stiff neck, vomiting, and sensitivity to light. Fortunately, herpes meningitis usually resolves after about a week without complications, although symptoms can recur. [stlukes-stl.com]
Skin
- Blister
When signs and symptoms are present, they consist of: Typically painful fluid-filled blisters (that may appear like " pimples ") around the vaginal area Blisters around the vagina, anus, or buttocks Ulcer formation after the blisters break open Blisters [medicinenet.com]
The baby may have clusters of fluid-filled blisters on their torso or around their eyes. The blisters, called vesicles, are the same type of blisters that appear on the genital regions of adults with herpes. [healthline.com]
Small, fluid-filled blisters ( vesicles ) may appear. These blisters break, crust over, and finally heal. A mild scar may remain. Herpes infection may also spread throughout the body. This is called disseminated herpes. [medlineplus.gov]
Most people with HSV-1 can shed it in their saliva with no symptoms, or they may have a cold sore: a small fluid filled skin blister which breaks open, crusts over, and disappears in about 21 days. [health.ny.gov]
- Skin Lesion
Day of life 11 skin lesions reappeared (see Figure 1 ), and acyclovir was readministered. [academic.oup.com]
The brain is involved (encephalitis) in 35 % of cases, with or without skin lesions. The poorest outcome is for the 25% of neonates who present with widespread (disseminated) disease, involving the lungs, liver, adrenal glands, skin, eye and mouth. [herpesguide.ca]
As in cases of CNS disease, skin lesions may not be present initially. [med.cmu.ac.th]
The most common abnormalities described after birth were skin lesions and keratitis, which are not considered amenable to prenatal ultrasound detection. [pubmed.ncbi.nlm.nih.gov]
There are three types of clinical manifestations related to this infection 2 : skin lesions without any visceral or central nervous system (CNS) involvement, also known as skin, eye and mouth disease CNS disease (with or without skin lesions, but without [radiopaedia.org]
- Pruritus
Genital herpes (herpes genitalis) Pathogen : HSV-2, HSV-1 (less common) Incubation period : 2–7 days Clinical findings Most patients are asymptomatic Genitals: redness, swelling, tingling, pain, pruritus Possibly unusual vaginal discharge Painful lymphadenopathy [amboss.com]
Associated symptoms may include pruritus, dysuria, vaginal discharge and tender regional lymphadenopathy. There is often a systemic prodrome of fever, malaise and myalgias one to two days before the appearance of lesions. [aafp.org]
Urogenital
- Genital Lesions
• Reactivation:-it is the isolation of same type of virus from genital lesions as that of pre-existing antibodies. 7. • Symptomatic shedding:- presence of genital lesions charecteristic of HSV and isolation of HSV 1 or 2 from the lesions. • Subclinical [slideshare.net]

Typically, localized small painful genital lesions (mean lesion area 10% of that in primary genital herpes). Footnote 1 Systemic symptoms in 5-12%. Prodromal symptoms in 43-53%, for an average of 1.2-1.5 days. Mean duration of lesion 9.3-10.6 days. [canada.ca]
Culture or antigen analysis of genital lesions will tell us the type of virus present (HSV-1 or HSV-2) but cannot distinguish a primary disease from a recurrent one. [herpesguide.ca]
- Cesarean Section
If the infection is acquired late in pregnancy, many providers would recommend a Cesarean section even without lesions present. [ashasexualhealth.org]
The current standard of care is that any woman with an active HSV lesion is delivered by cesarean section. [aafp.org]
Alternatively, if symptoms of first episode genital HSV infection begin within 4 to 6 weeks of delivery, the obstetrician may choose to deliver the infant by cesarean section. [med.cmu.ac.th]
If active genital herpes is diagnosed in a pregnant woman near term, cesarean section is usually recommended. HSV-2 infections have also been associated by circumstantial evidence with the later development of cervical cancer. [britannica.com]
If you're having an outbreak when you go into labor, your doctor will probably suggest a cesarean section to reduce the risk of passing the virus to your baby. Oct. 03, 2017 [mayoclinic.org]
Neurologic
- Irritability
For example, HSV type 1 can occur on the tongue near the teeth, which can cause extra irritation. [verywell.com]
Signs that your baby may have herpes are: irritability seizures trouble breathing, including grunting, blue appearance (cyanosis), rapid breathing and short periods of no breathing jaundice (yellow skin color) bleeding easily shock Herpes simplex infections [childrenshospital.org]
Symptoms of CNS herpes include irritability, seizures, tremors (uncontrollable shaking), and lethargy or tiredness. A swelling in the skull is also common. [diseaseinfosearch.org]
These include low grade fever (100.4 degrees F., or more, rectally), poor feeding, irritability, and skin rash in the form of pimples or blisters, seizures or other similar symptoms that may develop within six weeks following birth. [health.ny.gov]
Call a GP or your health visitor straight away if your baby: is lethargic or irritable isn't feeding has a high temperature (fever) – find out how to take your baby's temperature has a rash or sores on the skin, eye and inside the mouth These are early [nhs.uk]
- Lethargy
The examination was significant for mild lethargy, mild jaundice and a few scattered petechiae on the chest. [aafp.org]
Symptoms of CNS herpes include irritability, seizures, tremors (uncontrollable shaking), and lethargy or tiredness. A swelling in the skull is also common. [diseaseinfosearch.org]
The following factors were associated with neonatal HSV infection by univariate analysis: maternal primary HSV infection, maternal fever, vaginal delivery, prematurity, postnatal HSV contact, vesicular rash, hypothermia, lethargy, seizures, severe respiratory [journals.lww.com]
CNS) involvement, also known as skin, eye and mouth disease CNS disease (with or without skin lesions, but without involvement of visceral organs); usually this presentation has non-specific signs including decreased level of consciousness, seizures, lethargy [radiopaedia.org]
