Meningitis is an infection of the fluid of a person's spinal cord and the fluid that surrounds the brain. People sometimes refer to it as spinal meningitis. Meningitis is usually caused by a viral or bacterial infection. Knowing whether meningitis is caused by a virus or bacterium is important because the severity of illness and the treatment differ. Viral meningitis is generally less severe and resolves without specific treatment, while bacterial meningitis can be quite severe and may result in brain damage, hearing loss, or learning disability. For bacterial meningitis, it is also important to know which type of bacteria is causing the meningitis because antibiotics can prevent some types from spreading and infecting other people. Before the 1990s, Haemophilus influenzae type b (Hib) was the leading cause of bacterial meningitis, but new vaccines being given to all children as part of their routine immunizations have reduced the occurrence of invasive disease due to H. influenzae. Today, Streptococcus pneumoniae and Neisseria meningitidis are the leading causes of bacterial meningitis.
What is Meningitis?
Meningitis is an infection of the meninges that are membranes that cover the brain and the spinal cord.
In 2015, hundreds of children were born with brain deformities resulting from a global outbreak of Zika virus infections.
A team from the Institut national de la recherche scientifique (INRS) has demonstrated the effectiveness of an inexpensive molecule to fight antibiotic-resistant strains of the bacteria responsible for gonorrhea and meningococcal meningitis.
Rice University biochemists Michael Stern and James McNew have studied how neurodegeneration kills cells.
UC San Francisco scientists have developed a single clinical laboratory test capable of zeroing in on the microbial miscreant afflicting patients hospitalized with serious infections in as little as six hour.
As health leaders prepare to gather for a virtual session of the resumed 73rd World Health Assembly (WHA), WHO has three messages to share.
Scientists at The Wistar Institute have designed and tested the first-of-its-kind synthetic DNA vaccine against Powassan virus (POWV), targeting portions of the virus envelope protein.
It has recently been described that infection by some enteroviruses - a genus of viruses that commonly cause diseases of varying severity - could potentially trigger diabetes, although its direct effect 'in vivo' as well as its mechanism of action at the molecular level were unknown.
Scientists at Scripps Research have uncovered an important disease-fighting role for cells called hepatocytes, which constitute most of the liver. The discovery could potentially be harnessed to develop new medicines for viral illnesses.
Without directly invading the brain or nerves, the virus responsible for COVID-19 causes potentially damaging neurological injuries in about one in seven infected, a new study shows.
As the return of college students to campuses has fueled as many as 3,000 COVID-19 cases a day, keeping track of them is a logistical nightmare for local health departments and colleges.
German researchers published a report on a series of cases on post mortem findings of COVID-19 patients who succumbed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection along with neurological complications. Their study titled “Neuropathology of patients with COVID-19 in Germany: a post-mortem case series” is published in the latest issue of The Lancet Neurology.
COVID-19 pandemic has shown the world that vaccines should be prioritised, writes Githinji Gitahi. Imagine a world in which everyone is at risk of contracting a contagious disease with no prevention or cure.
In the United States, the Michigan Department of Health and Human Services (MDHHS) urge people to stay indoors, especially after dusk. Health officials have confirmed 22 horse cases of Eastern Equine Encephalitis (EEE), and one suspected human case.
Pesky, yet dangerous ticks are no longer latching exclusively onto hunters and outdoor enthusiasts. Milder winters and disrupted habitats have driven them out of the woods, with Lyme disease cases in the United States tripling since the late 1990s.
As co-director of school-based health centers at Bassett Healthcare Network, the pediatrician oversees about 21 school-based health clinics across the region — a poor, rural area known for manufacturing and crippled by the opioid epidemic.
One New Year's Day, Rob Purdie woke up with a headache that wouldn't quit. Vision problems, body aches and a slight fever followed. At the emergency room, the Bakersfield, California, resident was given antibiotics, which didn't touch his symptoms.
Researchers in the United States have demonstrated that a drug originally developed as a treatment for cancer exhibits antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).
In a major public health success, the introduction of pneumococcal conjugate vaccine PCV13, or Prevnar 13, in 2010 in the United States is associated with reduction in socioeconomic disparities and the near elimination of Black-white-based racial disparities for invasive pneumococcal disease.
Artificial intelligence, or "supervised machine learning," could help identify which well-appearing infants with fever, who are 60 days old or younger, are at low risk for a serious bacterial infection, according to a study published in Pediatrics.
Antibiotics are among the most important discoveries of modern medicine and have saved millions of lives since the discovery of penicillin almost 100 years ago.
