(Verse 1: Measles) In the world of viruses, where danger's close, Measles strikes with a contagious dose. RNA virus, single-stranded, no host but man, Spreading by droplets, it’s a global span. Incubation begins, eight to twelve days, Virus on the move, in so many ways. Prodromal phase with fever and spots, Cough, conjunctivitis, all tied in knots. Exanthemic rash, from head to feet, Antibodies fight, but immunity’s beat. Complications are many, pneumonia's near, Blindness, encephalitis, all to fear. (Chorus) Preventable infections, but they still creep, Vaccinate your children, don’t let them weep. From measles to polio, tetanus too, Keep them safe, it’s the right thing to do. (Verse 2: Mumps) Mumps sneaks in with a swollen face, Droplets spread it, leaves no trace. Parotid glands, they ache and swell, But in some, no symptoms tell. Neurotropic virus, CNS it invades, Meningoencephalitis, the body degrades. Orchitis, oophoritis, post-puberty’s plight, But sterility is rare, still, it’s a fright. (Bridge: Rubella) Rubella’s mild, but don’t be fooled, In pregnancy’s early weeks, it’s cruel. Foetal damage, up to twenty weeks, Screen the mothers, the danger peaks. A rash so faint, it’s hard to see, But brain damage and deafness can be. Vaccinate to protect, it’s the way, And keep congenital rubella at bay. (Chorus) Preventable infections, but they still creep, Vaccinate your children, don’t let them weep. From measles to polio, tetanus too, Keep them safe, it’s the right thing to do. (Verse 3: Pertussis) Pertussis strikes with a cough so fierce, Adheres to cilia, causing mucus tears. Catarrhal stage, then the paroxysms come, Coughing bouts, they leave you numb. Lymphocytosis rises, pneumonia’s near, Apnoea in infants, that’s the fear. Macrolides can help, but it’s not always sure, Vaccinate early, that’s the cure. (Verse 4: Diphtheria) Diphtheria’s toxin is the worst of all, A leathery membrane, it can enthrall. Spreads by droplets, by skin contact too, Pharynx, tonsils, it’ll glue. Bull neck, stridor, cardiomyopathy’s here, Neuropathy follows, it’s all so severe. Antitoxin’s needed, but beware the horse, Penicillin fights the bacterial force. (Bridge: Tetanus) Tetanus lurks in soil and dust, Clostridium tetani, in wounds it must. Neurotoxin travels, spasms begin, Opisthotonic rigidity, no way to win. Vaccinate well, don’t let it thrive, Even after infection, stay alive. Muscle relaxants, ventilation too, Tetanus toxoid, keep it in view. (Verse 5: Polio) Polio’s virus, in water and food, Infects the gut, then CNS it’s pursued. In most, it’s silent, immunity’s earned, But in some, paralysis is learned. Asymmetrical weakness, motor neurons fade, Iron lungs for those, who needed aid. Vaccination saved millions, that’s clear, But the fight’s not over, don’t disappear. (Chorus) Preventable infections, but they still creep, Vaccinate your children, don’t let them weep. From measles to polio, tetanus too, Keep them safe, it’s the right thin
