Inflammation (swelling) of the protective membranes covering the brain and spinal cord
Incubation Period
Between two and 10 days
Mode of transmission
1. Bacteria are transmitted from person-to-person through droplets of respiratory or throat secretions from carriers
2. Smoking, close and prolonged contact – such as kissing, sneezing or coughing on someone, or living in close quarters with a carrier – facilitates the spread of the disease
Meningococcal vaccines
Meningococcal polysaccharide vaccine (MPSV4)
Meningococcal conjugate vaccine (MCV4)
Serogroup B meningococcal vaccine
Signs and symptoms of meningitis
nausea and vomiting
fever
headache and a stiff neck
muscle pain
sensitivity to light
confusion
cold hands or feet and mottled skin
Diagnosis
Spinal tap to collect cerebrospinal fluid (CSF)
Meningitis treatments
Cephalosporins (Claforan, Rocephin)
Penicillin-type antibiotics
Aminoglycoside drugs (gentamicin)
Listeriosis
Serious infection caused by the germ Listeria monocytogenes
Incubation Period
1 to over 90 days, average 30 days
Mode of Transmission
1. Eating food contaminated with the bacteria, such as through raw (unpasteurized) milk or contaminated vegetables
2. Bacteria may be passed from mother to fetus during pregnancy or directly to the newborn at the time of birth
No vaccine for listeriosis
Signs and Symptoms of listeriosis
Headache
Stiff neck
Confusion or changes in alertness
Loss of balance
Convulsions
Diagnosis
Bacterial culture to grow Listeria monocytogenes from a body tissue or fluid
Treatment
Mild cases require no treatment, more serious infections treated with antibiotics
Tetanus
Serious infection caused by Clostridium tetani, affects the brain and nervous system
Incubation Period
Average 7 to 10 days
Tetanus is not transmitted from person to person
Tetanus vaccines
DTaP (diphtheria, tetanus, whooping cough)
DT (diphtheria, tetanus)
Tdap (tetanus, diphtheria, whooping cough)
Signs and Symptoms of tetanus
Stiffness of the neck, jaw, and other muscles
Difficulty swallowing
Fever
Sweating
Uncontrollable spasms of the jaw (lockjaw) and neck muscles
Painful, involuntary contraction of other muscles
Diagnosis
Based on physical exam, medical/immunization history, and signs/symptoms
Tetanus treatments
Antitoxin
Antibiotics
Tetanus vaccine
Sedatives
Other drugs (magnesium sulfate, beta blockers, morphine)
Supportive therapies for severe tetanus include ventilator support
Poliomyelitis (Polio)
Disabling and life-threatening disease caused by the poliovirus, spreads from person to person and can infect the spinal cord causing paralysis
Incubation Period
6 days for nonparalytic polio, 7-21 days for onset of paralysis in paralytic polio
Mode of Transmission
Spread through faeces and saliva, primarily faecal-oral spread, 'live' oral polio vaccine virus can also lead to infection in unvaccinated contacts
Polio vaccines
Inactivated polio vaccine (IPV)
Oral polio vaccine (OPV)
Signs and Symptoms of polio
Fever
Sore throat
Headache
Vomiting
Fatigue
Back pain or stiffness
Neck pain or stiffness
Pain or stiffness in the arms or legs
Diagnosis
Recognized by symptoms, confirmed by testing throat secretions, stool, or cerebrospinal fluid for poliovirus
Treatment
No cure, supportive treatments like bed rest, pain control, good nutrition, and physical therapy
Rabies
Viral disease that causes inflammation of the brain in humans and other mammals
Incubation Period
Generally 20–60 days, can be as short as 5–6 days or as long as 7 years
Mode of transmission
Spread through the saliva of infected animals, usually by biting, can also spread through infected saliva in open wounds or mucous membranes
Rabies vaccines
Rabies vaccine
Rabies immune globulin (RIG)
Signs and symptoms of rabies
irritability or aggressiveness
excessive movements or agitation
confusion, bizarre or strange thoughts, or hallucinations
muscle spasms and unusual postures
seizures (convulsions)
weakness or paralysis
Diagnosis
In animals - direct fluorescent antibody (DFA) test, in humans - multiple tests required
Rabies treatment
Rabies immune globulin shot
Series of rabies vaccinations
Encephalitis
Inflammation of the brain, most often due to viral infection
Incubation Period
4 to 10 days for Eastern equine encephalitis virus (EEEV)
Mode of Transmission
Coughs/sneezes releasing airborne viruses, reactivation of dormant viral infections
Japanese encephalitis vaccine
Inactivated Vero cell culture-derived Japanese encephalitis (JE) vaccine (IXIARO)
