how is viral meningitis spread?
449112
Viral meningitis The enteroviruses that cause meningitis can spread through direct contact with saliva, nasal mucus, or feces. They easily spread through coughing and sneezing. Direct or indirect contact with an infected person increases your risk of getting the same virus.

Variola virus is most frequently transmitted from an infectious person via direct deposition of large, infective airborne droplets of saliva onto the nasal, oral or pharyngeal mucosal membranes, during close, face-to-face contact with a susceptible individual.

Anyone can get aseptic meningitis, but the highest rates occur among children under age 5. The vaccines that protect children from bacterial meningitis aren't always effective against aseptic meningitis, which is caused by viruses and other organisms.

Viral meningitis usually begins with symptoms of a viral infection, such as fever, a general feeling of illness (malaise), cough, muscle aches, vomiting, loss of appetite, and headache. However, occasionally, people have no symptoms at first.

For viral aseptic meningitis, risk factors include those for the specific agents. Enteroviruses can be transmitted by exposure to an infected individual's secretions entering the oral cavity through sneezing or oral fecal contact.

Meningitis is an infection of the tissues covering the brain and spinal cord (meninges). Viral meningitis is an infection caused by viruses and bacterial meningitis is an infection caused by bacteria.

Bacterial meningitis is usually less contagious than viral; depending on the bacterial genus causing the infection, it may be contagious during the incubation period and for about an additional seven to 14 days. And they can be contagious for much longer (many days to months) if the person becomes a carrier.

Symptoms come on quickly and include severe headache, stiff neck, fever, and sometimes vomiting. The neck stiffness makes it hard or impossible to touch the chin to the chest. The flu, which usually is not serious, can cause symptoms similar to meningitis.
337435
Viral meningitis presents with similar symptoms to bacterial meningitis such as fever, headache, dislike of lights and neck stiffness. It can present with a rash, but this is normally quite different to the rash seen in bacterial meningitis with meningococcal disease. Viral meningitis is almost never life-threatening.

Bacterial meningitis occurs when bacteria infect the lining of the brain (the meninges) and the spinal cord. Meningococcal septicaemia – or blood poisoning – occurs when the bacteria in the blood multiply uncontrollably.

The first symptoms of meningitis typically happen very quickly – much like the flu, the symptoms of meningitis can come on quite suddenly and progress in a short amount of time.

Meningitis is an infection of the tissues covering the brain and spinal cord (meninges). Viral meningitis is an infection caused by viruses and bacterial meningitis is an infection caused by bacteria. What is the difference between viral and bacterial meningitis?

Your baby can get meningitis when bacteria, viruses, or a fungus infecting another part of their body travels in the bloodstream to their brain and spinal cord. Out of 1,000 live births, about 0.1 to 0.4 neonates (a baby less than 28 days old) get meningitis, estimates a 2017 review.

The condition is called aseptic meningitis when not caused by bacteria. Viruses cause most aseptic meningitis cases, which is why the condition is also known as viral meningitis. Aseptic meningitis is more common than bacterial meningitis. But its symptoms are usually less severe.

Bacterial meningitis leads to a more permeable blood brain barrier (due to increased inflammation). Protein leaks into the subarachnoid space from the blood, resulting in markedly increased CSF protein levels.
156956
Acute syphilitic meningitis, also known as meningeal syphilis, presents much the same as viral meningitis and bacterial meningitis do, with symptoms such as a stiff neck, a headache, nausea and vomiting. In some cases, the affected person may lose vision or hearing.

The virus is transmitted through saliva, and can be passed from person to person through kissing. It can also be spread via sneezing, coughing or sharing eating utensils, drinking containers or by sucking on toys. Most adults have been exposed to EBV at some time in their lives and are immune to glandular fever.
