This species appears to be particularly damaging to the nervous system, and some research has attributed Herpes simplex virus 1 infection to an increased risk of developing Alzheimer's disease. The virus interacts with the components and receptors of lipoproteins, which may lead to the development of Alzheimer's disease. [7]
It is estimated to affect at least 1 in 500,000 individuals per year, [1] and some studies suggest an incidence rate of 5.9 cases per 100,000 live births. [2] About 90% of cases of herpes encephalitis are caused by herpes simplex virus-1 (HSV-1), the same virus that causes cold sores.
Herpes simplex virus 1 and 2 (HSV-1 and HSV-2) are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans. [1] [2] Both HSV-1 and HSV-2 are very common and contagious. They can be spread when an infected person begins shedding the virus.
HSV-1 can in rare cases be transmitted to newborn babies by family members or hospital staff who have cold sores; this can cause a severe disease called neonatal herpes simplex. People can transfer the virus from their cold sores to other areas of the body, such as the eye, skin, or fingers; this is called autoinoculation .
The annual incidence in Canada of genital herpes due to HSV-1 and HSV-2 infection is not known (for a review of HSV-1/HSV-2 prevalence and incidence studies worldwide, see Smith and Robinson 2002). As many as one in seven Canadians aged 14 to 59 may be infected with herpes simplex type 2 virus [ 89 ] and more than 90 per cent of them may be ...
The disease people develop after eating food contaminated with this bacteria is called listeriosis. What the symptoms are: Mild symptoms of listeriosis include fever, muscle aches, nausea ...
How long do symptoms last? They peak at 24 to 48 hours but can last up to 72 hours, says Dr. Dibba. Norovirus tends to hit hard and then fade fairly quickly. Symptoms do ramp up in intensity, however.
The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2. HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions. Both HSV-1, and HSV-2 can be the cause of herpetic gingivostomatitis, [5] although HSV-1 is the source ...
