the "kissing disease"‚ because the most frequent mode of transmission is intimate salivary contact. It can also be transmitted from shared drinking and eating utensils‚ toothbrushes‚ etc. Mono is not likely to spread by aerosol (ex. sneezing) or fomites (ex. doorknobs). About half the population is not exposed to this virus until late adolescence. The peak incidence for girls is 14-16 and boys 16-18. After initial contact with the virus‚ there is an incubation period of 4-6 weeks and then the symptoms

P1: you must explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. P2: you must explain how pathogenic microorganisms grow and spread. In this assignment I am going to explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. I will then explain how pathogenic microorganisms grow and spread. Infection is the process where germs enter a susceptible area in the body‚ where they multiply‚ resulting in disease. Colonisation is where microbes are present

(Include a description of the envelope‚ capsid‚ and core The nucleic acid of a virus is protected by a protein coat called the capsid. The structure of the capsid is ultimately determined by the viral nucleic acid and accounts for most of the mass of a virus‚ especially of small ones. Each capsid

Newly emerged impregnated females will crawl onto the uninfected person. The mite will hold onto the skin using suckers attached to the two most anterior pairs of legs. They will then burrow into the skin. Transmission may also occur via fomites (e.g.‚ bedding or clothing). Sarcoptes scabei undergoes four stages in its life cycle; egg‚ larva‚ nymph and adult. Sarcoptic mites form definite burrows under the skin in which females deposit eggs. Females deposit eggs at 2 to 3 day intervals as
