Herpes simplex encephalitis (HSE), or simply herpes encephalitis, is encephalitis due to herpes simplex virus. 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.
Death from neonatal HSV disease in the U.S. is currently decreasing; the current death rate is about 25%, down from as high as 85% in untreated cases just a few decades ago. Other complications from neonatal herpes include prematurity, with approximately 50% of cases having a gestation of 38 weeks or less, and concurrent sepsis in approximately ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
In 2015, encephalitis was estimated to have affected 4.3 million people and resulted in 150,000 deaths worldwide. [4] [3] Herpes simplex encephalitis has an incidence of 2–4 per million of the population per year. [36]
If treated, most individuals recover from viral encephalitis without long-term problems related to the illness. Mortality rates vary for those who do not receive treatment, for example being about 70% for herpes encephalitis [13] but low for the La Crosse virus. Individuals who remain symptomatic after initial infection may have difficulty ...
Acute necrotizing encephalopathy (ANE) or sometimes necrotizing encephalitis or infection-induced acute encephalopathy (IIAE) is a rare type of brain disease (encephalopathy) that occurs following a viral infection. [4] Most commonly, it develops secondary to infection with influenza A, influenza B, and the human herpes virus 6. ANE can be ...
Each year during that time span, around 400 to 500 people died, 48,000 were hospitalized and 4,000 suffered encephalitis (swelling of the brain) caused by measles, said the CDC.
A 2021 study using a high spatial resolution model and an updated concentration-response function finds that 10.2 million global excess deaths in 2012 and 8.7 million in 2018 – or a fifth [dubious – discuss] – were due to air pollution generated by fossil fuel combustion, significantly higher than earlier estimates and with spatially ...
