EMERGENCY:Fever + severe headache + neck stiffness = possible bacterial meningitis —call040-46324365immediately — 24 hours, 7 days— 24/7
Expert immediate triage of suspected bacterial meningitis, same-hour CT and lumbar puncture pathway, IV ceftriaxone and dexamethasone within minutes of LP, and full treatment of all four meningitis types — bacterial, viral, fungal/cryptococcal, and tuberculous — at KIMS Neuroscience, Secunderabad, Hyderabad.
Meningitis is inflammation of the meninges — the three-layered membrane enveloping the brain and spinal cord. Four principal types in India: bacterial (Streptococcus pneumoniae, Neisseria meningitidis; life-threatening emergency requiring immediate empirical antibiotics), viral (usually self-limiting), fungal/cryptococcal (predominantly in HIV patients with CD4 below 100; fatal without prolonged antifungal therapy), and tuberculous (TBM; the most common chronic meningitis across India, driven by India's TB burden; subacute onset over 1–4 weeks; CN VI palsy + basilar exudate + hydrocephalus on MRI; treated with 9–12 months ATT + dexamethasone). India has approximately 60,000 meningitis deaths annually. The most important clinical principle: empirical antibiotics are NEVER delayed while waiting for imaging. The triad: fever + severe headache + neck stiffness = bacterial meningitis until LP proves otherwise.

Bacterial meningitis kills within 24 hours when untreated
Bacterial meningitis kills within 24 hours when untreated. It kills within 24 hours in some cases even with treatment, when treatment starts too late. The single most important determinant of outcome in bacterial meningitis is the time from first symptom to first antibiotic dose. Every hour of delay corresponds to measurably worse survival and neurological outcome. This is the message that every person in India must understand about meningitis: it is not a condition that can wait until morning.
The essential facts that shape how meningitis is recognised, triaged, and treated at KIMS — from the meningeal triad and India's specific epidemiological burden to the central role of the lumbar puncture in distinguishing bacterial, viral, fungal, and tuberculous causes.
Inflammation of the meninges — the three-layered membrane (dura mater, arachnoid mater, pia mater) that envelops the brain and spinal cord. Meningitis can be caused by bacteria, viruses, fungi, parasites, or non-infectious conditions. The cause determines the urgency, the treatment, and the prognosis. Bacterial meningitis is a life-threatening emergency requiring immediate treatment within hours. Viral meningitis is usually self-limiting but serious. Fungal meningitis occurs predominantly in immunocompromised patients and is fatal without prolonged antifungal therapy. Tuberculous meningitis — the form most relevant to India — presents subacutely and requires prolonged antitubercular treatment with steroids.
Fever · Severe headache · Neck stiffness (meningism). This triad is present in approximately 44–87% of bacterial meningitis cases. Other warning signs: photophobia (light sensitivity), phonophobia (sound sensitivity), nausea and vomiting, altered consciousness or confusion, seizures. In infants, the presentation is different: bulging fontanelle, poor feeding, high-pitched cry, irritability, rash. A non-blanching purpuric rash indicates meningococcal septicaemia — the most rapidly fatal form.
GBD 2016 estimated meningitis incidence in India at 60–80 per 100,000, with approximately 60,000 deaths annually. In India, Streptococcus pneumoniae and Neisseria meningitidis are the predominant bacterial pathogens. Tuberculous meningitis (TBM) is the most common cause of chronic meningitis across India, driven by India’s TB burden. Cryptococcal meningitis is increasingly important in the setting of HIV co-infection.
A lumbar puncture (LP, spinal tap) — sampling the cerebrospinal fluid (CSF) that bathes the brain and spinal cord — is the most important investigation for meningitis. CSF analysis identifies the pathogen, guides specific treatment, and distinguishes bacterial from viral from fungal from tuberculous meningitis. At KIMS, LP is performed promptly in any patient with suspected meningitis where CT brain has excluded raised ICP that makes LP unsafe.

A 22-year-old man in Hyderabad wakes at 3am with the most severe headache of his life. By 5am, his neck is so stiff he cannot bring his chin to his chest. His temperature is 39.8°C. His parents debate whether to wait until the clinic opens at 9am. By 8am, he is confused and difficult to rouse. His family calls 040-46324365. He arrives at KIMS at 8:30am. CT brain is clear. A lumbar puncture is performed immediately: turbid CSF with 4,200 white cells (predominantly neutrophils), protein 3.2 g/L, glucose 0.9 mmol/L (blood glucose 5.8 mmol/L). CSF Gram stain shows Gram-positive diplococci. Diagnosis: pneumococcal meningitis. IV ceftriaxone and dexamethasone are started within 20 minutes of LP.
He survives. He has mild residual hearing loss in his left ear. If treatment had been delayed by 6 hours — until the clinic opened — the outcome would most likely have been different.
Bacterial meningitis kills within 24 hours when untreated. It kills within 24 hours in some cases even with treatment, when treatment starts too late. The single most important determinant of outcome in bacterial meningitis is the time from first symptom to first antibiotic dose. Every hour of delay corresponds to measurably worse survival and neurological outcome. This is the message that every person in India must understand about meningitis: it is not a condition that can wait until morning.
Fever, severe headache, and neck stiffness require immediate hospital assessment — not an outpatient appointment. KIMS Neuroscience runs an immediate triage pathway with same-hour CT, LP, and empirical antibiotics for any suspected bacterial meningitis.
040-44885000Appointment line: 040-44885000Not all meningitis is the same. The cards below compare the four main infectious types — bacterial, viral, fungal/ cryptococcal, and tuberculous — across onset, fever, headache, CSF findings, treatment, and outcome without treatment, alongside the bacterial pathogens by age, the meningococcal-septicaemia rash emergency, India's TBM burden, and the cryptococcal pattern in immunocompromised hosts.
Onset hours to 1–2 days. High, sudden fever; severe, sudden headache.
CSF: >1,000 PMNs (neutrophils), very low glucose (<40% of blood), very high protein (>1 g/L).
Treatment: IV cephalosporin + dexamethasone. Outcome without treatment: death within 24–48 hours.
The single most important determinant of outcome is the time from first symptom to first antibiotic dose.
Onset days to 1–2 weeks. Moderate to high fever; moderate to severe headache.
CSF: 10–500 lymphocytes, normal glucose, normal or mildly raised protein.
Treatment: supportive; antivirals if HSV.
Outcome without treatment: usually self-limiting (except HSE — herpes simplex encephalitis, which is rapidly fatal without aciclovir).
Subacute onset over days to weeks. Variable fever, often low-grade; moderate, worsening headache.
CSF: 10–500 lymphocytes (initially PMNs), normal or slightly low glucose, normal or mildly raised protein.
Treatment: antifungals (amphotericin + flucytosine). Outcome without treatment: death within weeks.
Predominantly affects HIV patients with CD4 below 100 cells/μL or those on immunosuppressive therapy.
Subacute to chronic onset over weeks. Low-grade, persistent fever; severe, progressive headache.
CSF: 10–500 lymphocytes with low glucose, very low CSF glucose (<40% of blood), very high protein (>1 g/L).
Treatment: 4-drug ATT + dexamethasone. Outcome without treatment: death within weeks to months.
The most common cause of chronic meningitis across India, driven by India’s TB burden.
Neonates (≤3 months): Group B Streptococcus, Escherichia coli, Listeria monocytogenes.
Infants and children: Streptococcus pneumoniae (pneumococcus), Neisseria meningitidis (meningococcus), Haemophilus influenzae type b (Hib).
Adults: Streptococcus pneumoniae (most common overall in India), Neisseria meningitidis, Listeria (in older adults >50 and immunocompromised).
Post-neurosurgery: Staphylococcus aureus, Gram-negative organisms.
Neisseria meningitidis can cause pure meningitis, pure septicaemia, or both together.
Meningococcal septicaemia produces a characteristic non-blanching purpuric rash (small, flat red-purple spots that do not fade when pressed with a glass) from bacterial invasion of small blood vessels.
This rash indicates a life-threatening emergency — blood pressure can collapse within hours.
In India, any patient with fever, confusion, and a non-blanching rash should be given IM benzylpenicillin or ceftriaxone immediately, even before hospital arrival.
TBM is the meningitis form most commonly encountered in Indian neurology practice. It presents subacutely: 1–4 weeks of low-grade fever, progressive headache, vomiting, weight loss, then neck stiffness and cranial nerve palsies (CN VI palsy — lateral gaze palsy — is particularly characteristic), and eventually altered consciousness.
CSF shows lymphocytic pleocytosis, very low glucose, and very high protein. Adenosine deaminase (ADA) is elevated. CBNAAT (GeneXpert MTB/RIF) on CSF is the fastest molecular test. MRI brain shows basilar exudate (leptomeningeal enhancement at the base of the brain), hydrocephalus (common), and infarcts.
Treatment: isoniazid + rifampicin + pyrazinamide + ethambutol for 2 months (intensive phase), then isoniazid + rifampicin for 7–10 months (maintenance phase), with dexamethasone throughout the initial 6–8 weeks.
TBM carries a significant mortality (approximately 25–30%) and neurological morbidity even with treatment.
Cryptococcus neoformans is an encapsulated yeast that causes meningitis predominantly in patients with CD4 count below 100 cells/μL in HIV disease, or in those on immunosuppressive therapy.
Presents subacutely with fever, headache, and confusion. The India ink stain of CSF reveals encapsulated yeast cells; cryptococcal antigen (CrAg) is highly sensitive.
Treatment: liposomal amphotericin B 3–5 mg/kg/day + flucytosine 100 mg/kg/day for 2 weeks (induction), then fluconazole 400mg/day for 8 weeks (consolidation), then fluconazole 200mg/day long-term maintenance.
Raised intracranial pressure from cryptococcal meningitis — managed with serial therapeutic LPs or VP shunt — is a major cause of death and must be actively managed at KIMS.
Meningitis presents with the meningeal triad of fever, severe headache, and neck stiffness; other warning signs such as photophobia, phonophobia, nausea, and vomiting; altered consciousness and seizures as the brain is involved; a distinctly different infant presentation; the non-blanching rash that signals meningococcal septicaemia; and the substantial complications and sequelae that follow even successfully treated bacterial meningitis.
Fever · Severe headache · Neck stiffness (meningism). This triad is present in approximately 44–87% of bacterial meningitis cases. Kernig’s sign (inability to extend the knee when the hip is flexed at 90°) and Brudzinski’s sign (flexion of the knees and hips in response to passive neck flexion) confirm meningism on KIMS examination.
Photophobia (light sensitivity), phonophobia (sound sensitivity), and nausea and vomiting accompany the meningeal triad in many bacterial meningitis presentations. These features prompt urgent assessment when paired with fever and headache, even if neck stiffness is not yet pronounced.
Altered consciousness or confusion and seizures occur as bacterial meningitis progresses. Level of consciousness (GCS score) is documented at the KIMS bedside; deterioration in GCS is one of the markers triggering CT brain before LP. Seizures may be focal or generalised.
In infants, the presentation is different from adults: bulging fontanelle, poor feeding, high-pitched cry, irritability, rash. The classical meningeal signs may be absent in this age group. Any infant with fever and any of these features needs immediate paediatric assessment at KIMS.
A non-blanching purpuric rash indicates meningococcal septicaemia — the most rapidly fatal form. The rash is small, flat, red-purple, and does not fade when pressed with a glass (the glass test). Cardiovascular collapse can occur within hours; in India, IM benzylpenicillin or ceftriaxone should be given immediately, even before hospital arrival.
Bacterial meningitis causes significant permanent neurological damage even when treated and survived: sensorineural hearing loss in approximately 30% of survivors of pneumococcal meningitis (audiological assessment at KIMS at 6–8 weeks); cognitive impairment in children and adults; post-meningitic epilepsy in approximately 15–25%; hydrocephalus from inflammation/exudate (may need VP shunting); limb amputation from meningococcal septicaemia (DIC, small-vessel thrombosis); death — bacterial meningitis CFR ~15–25% in adults in India, TBM CFR ~25–30%.
Meningitis diagnosis at KIMS uses a strict immediate-triage protocol — clinical assessment first, CT brain only where raised ICP is suspected, lumbar puncture as the diagnostic gold standard with a full simultaneous CSF panel, and MRI brain for complications and pathogen-specific patterns — with empirical antibiotics never delayed for any of these investigations.
Any patient presenting with fever + headache + neck stiffness (the meningeal triad) is assessed immediately as a possible bacterial meningitis at KIMS. Kernig’s sign (inability to extend the knee when the hip is flexed at 90°) and Brudzinski’s sign (flexion of the knees and hips in response to passive neck flexion) confirm meningism. Petechial or purpuric rash is sought. Fundoscopy for papilloedema. Level of consciousness (GCS score). Vital signs for septic shock. Blood cultures (two sets) drawn immediately before antibiotics.
CT brain is performed before LP only when there are signs of raised intracranial pressure (papilloedema on fundoscopy, unequal pupils, GCS deterioration, or focal neurological signs) that make LP potentially dangerous. If CT is clear, LP is performed immediately. CRITICAL: Antibiotics are NEVER delayed to wait for CT. In suspected bacterial meningitis, if CT cannot be performed within 30 minutes, antibiotics are given first and LP performed after. At KIMS, this protocol is followed strictly.
CSF sent for: cell count and differential (PMN predominance = bacterial; lymphocyte predominance = viral, fungal, or TBM); glucose (with simultaneous blood glucose — CSF:blood ratio <0.5 suggests bacterial or TB meningitis); protein; Gram stain and bacterial culture; India ink stain (for Cryptococcus); cryptococcal antigen; AFB smear and Mycobacterium culture; CBNAAT (GeneXpert) for TB; viral PCR panel (HSV, Enterovirus, CMV, EBV, JEV); adenosine deaminase (ADA) for TBM. At KIMS, all CSF tests are arranged simultaneously from a single LP with appropriate CSF volumes collected.
MRI brain with gadolinium identifies: leptomeningeal enhancement (meningitis); brain abscess (if untreated bacterial meningitis has progressed to collection); basal exudate and cranial nerve enhancement (TBM); hydrocephalus; cerebral infarcts (complication of TBM or bacterial meningitis from vasculitis); and cerebral venous thrombosis (a complication of meningitis requiring anticoagulation).
The KIMS treatment protocol for suspected bacterial meningitis: start immediately — do not wait for LP results.
(1) IV ceftriaxone 2g every 12 hours (4g for adults). (2) IV dexamethasone 0.15 mg/kg every 6 hours for 4 days — reduces mortality and deafness in pneumococcal meningitis. (3) IV ampicillin 2g every 4 hours if age >50 or immunocompromised (for Listeria coverage). (4) Consider adding vancomycin if penicillin-resistant pneumococcus suspected.
Antibiotics are narrowed to the most appropriate agent when culture and sensitivity results are available at 48–72 hours.
Intensive phase (2 months): isoniazid + rifampicin + pyrazinamide + ethambutol daily. Continuation phase (7–10 months): isoniazid + rifampicin.
Dexamethasone 0.4 mg/kg/day for 4 weeks, then tapered over the next 4 weeks. Pyridoxine (vitamin B6) 25–50mg daily with isoniazid (to prevent peripheral neuropathy).
Hydrocephalus — a common TBM complication managed at KIMS with VP shunting when CSF protein is not obstructive.
Liposomal amphotericin B 3–5 mg/kg/day + flucytosine 100 mg/kg/day for 2 weeks (induction). Fluconazole 400–800mg/day for 8 weeks (consolidation). Fluconazole 200mg/day indefinitely (maintenance in HIV) or until immune reconstitution.
Therapeutic lumbar punctures (TLPs): if opening pressure >25 cmH₂O, daily TLPs removing 20–30ml CSF until pressure normalises. VP shunt if refractory raised ICP.
Most viral meningitis is self-limiting and managed with: adequate hydration, analgesia for headache, antiemetics for nausea, rest.
Antiviral acyclovir is given empirically if HSV meningitis or encephalitis cannot be excluded while awaiting PCR.
Enteroviral meningitis: supportive management. EBV, CMV, HIV meningitis: specific antiviral therapy for the underlying virus.
Sensorineural hearing loss: the most common sequel of bacterial (especially pneumococcal) meningitis — occurring in approximately 30% of survivors. Audiological assessment at KIMS at 6–8 weeks post-meningitis.
Cognitive impairment: learning difficulties and memory problems in children who survive bacterial meningitis; cognitive deficits in adults. Epilepsy: post-meningitic seizures occur in approximately 15–25% of survivors.
Hydrocephalus: obstruction of CSF drainage by meningeal inflammation or exudate. May require VP shunting at KIMS. Limb amputation: meningococcal septicaemia causes limb ischaemia and gangrene from DIC and small vessel thrombosis, requiring amputation in some survivors. Death: despite treatment, bacterial meningitis mortality remains approximately 15–25% in adults in India; TBM mortality approximately 25–30%.
