Las paredes externas de una casa o un automóvil brindan una barrera fuerte e inflexible que protege a sus habitantes humanos de un mundo externo rudo e impredecible. Podría esperarse que el límite externo de una célula viva estuviera construido de una barrera igual de fuerte e impenetrable porque también debe proteger su delicado contenido interno ante un ambiente no vivo y a menudo inhospitalario. Sin embargo, las células están separadas del mundo externo por una estructura delgada y frágil llamada membrana plasmática que sólo mide 5 a 10 nm de espesor.

Before the vaccine, whooping cough was thought to be a childhood disease. Whooping cough now primarily affects children who have not received the full course of vaccinations, as well as teenagers and adults whose immunity has waned.
Deaths from whooping cough are uncommon, but most commonly occur in infants. That is why it is critical for pregnant women and others who will have close contact with an infant to be immunized against whooping cough. The best way to avoid pertussis is to get vaccinated. Check that you and your loved ones have received their pertussis vaccines.
