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.
Researchers in the United States and Canada have mapped the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the brains of people who died from coronavirus disease 2019 (COVID-19).
A team of scientists from the United States has recently conducted a study using pericyte-like cell-containing brain cortical organoids as an experimental model to investigate the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the central nervous system.
A study recently published in the journal Cureus has described a case report of a coronavirus disease 2019 (COVID-19) patient who presented with pneumonia, posterior reversible encephalopathy syndrome (PRES), and persistent cortical blindness. A detailed clinical presentation of the patient is provided in the report.
Malaria is one of the most common causes of death in children in Africa and is triggered by a small parasite that lives in the blood. When the parasite builds up in the blood vessels of the brain, it develops into one of the most dangerous forms of the disease, cerebral malaria.
Synthetic cannabidiol, better known as CBD, has been shown for the first time to kill the bacteria responsible for gonorrhea, meningitis and legionnaires disease.
At the 73rd Session of the World Health Assembly, Member States overwhelmingly endorsed a resolution calling for urgent action on meningitis prevention and control through the implementation of a bold, comprehensive global roadmap to defeat meningitis by 2030.
The four leading international health and humanitarian organizations announced today the establishment of a global Ebola vaccine stockpile to ensure outbreak response.
Healthcare workers in tropical and sub-tropical settings where strongyloidiasis is prevalent or caring for patients who have travelled to such areas, need to maintain a high level of awareness about the use of corticosteroids, including when this class of anti-inflammatories is given to patients suspected of infection with SARS-CoV-2.
Researchers demonstrated that neuroinvasion and encephalitis caused by SARS-CoV-2 is associated with significant mortality in a special mouse model.
Researchers at the University of Maryland School of Medicine published one of the most comprehensive analyses of how genes get expressed during infection (known as a transcriptome). The analyses include three different strains of the bacteria Streptococcus pneumoniae, which causes pneumonia, meningitis, and middle-ear infections.
Researchers at Karolinska Institutet in Sweden have come one step closer toward understanding why some people become seriously ill or die from a common bacterium that leaves most people unharmed.
A team of researchers at the University of Toronto in Canada has found that melatonin can be an adjuvant to augment the efficacy of anti-SARS-CoV-2 vaccines. They believe that the drug is a potential “silver bullet” to combat the COVID-19 pandemic.
Antibiotics are used to prevent and treat bacterial infections. They have played a major role in combating infectious diseases such as tuberculosis, pneumonia, typhoid fever, and meningitis in 20th century.
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.
