Answer: You can get mono from making out with people, which is why it is sometimes called the "kissing disease." An uninfected but susceptible individual receives the virus from the saliva of someone who already has it (a carrier), and it can trigger the outbreak of the associated disease. Most people exposed to the virus have few or no symptoms.
Answer: A cold is a virus and you catch it from someone else or by touching something someone else has touched. This is why you should wash your hands a lot during cold season. You do not catch a cold from being cold.
Answer: Scarlet fever is usually contracted by other people who have it, through direct contact. Such as through the bacteria that lands on dust, or water droplets. Another way of getting it is from streptococcal toxins that seem in through the skin causing the rash.
Answer: Salmonellosis is an infection with Salmonella bacteria. Most people infected with Salmonella develop diarrhea, fever, vomiting, and abdominal cramps 12 to 72 hours after infection. In most cases, the illness lasts four to seven days, and most people recover without treatment. However, in some cases the diarrhea may be so severe that the patient becomes dangerously dehydrated and must be taken to a hospital. At the hospital, the patient may receive intravenous fluids to treat the dehydration, and may be given medications to provide symptomatic relief, such as fever reduction. In severe cases, the Salmonella infection may spread from the intestines to the blood stream, and then to other body sites, and can cause death unless the person is treated promptly with antibiotics. The elderly, infants, and those with impaired immune systems are more likely to develop severe illness. Some people afflicted with salmonellosis later experience reactive arthritis, which can have long-lasting, disabling effects. There are different kinds of Salmonella, including S. bongori and S. enterica. The type of Salmonella usually associated with infections in humans, nontyphoidal Salmonella, is usually contracted from sources such as:
Poultry, pork, and beef, if the meat is prepared incorrectly or is infected with the bacteria after preparation.
Infected eggs, egg products, and milk when not prepared, handled, or refrigerated properly.
Reptiles, such as turtles, lizards, and snakes, which may carry the bacteria on their skin.
Answer: Through infection by Yersinia Pestis (a bacterium). The method of infection can vary, but traditionally the bacterium is carried by host fleas that will bite an animal to feed, thus penetrating the skin and introducing the pathogen into the lymphatic system.
Answer: Rickets is a bone disease caused by severe calcium deficiency in children. The classic symptom of rickets is bowing of legs because there is not enough calcium to build the long bones.
Contracted is not the best word to use, as it almost assumes that rickets is a contagious disease which it is not. Causes of Rickets -severe calcium deficiency -severe vitamin D deficiency (vitamin D is needed for the absorption of calcium)
Like other nutrient deficiencies, the cause can either be from a lack of that nutrient in the diet, or perhaps a gastrointestinal disorder which prevents the body from absorbing the nutrient from the digestive tract.
Answer: Pneumonia is mostly contracted by breathing in small air particles that have microorganisms harmful to the respiratory system. When someone sneezes or coughs, germs contained in these particles enter the surrounding atmosphere and is made readily available for someone else to breath in.
Answer: Its actually MRSA (Methycillin Resistant Staphlococcus aureus) also know as ORSA (Oxacillin Resistant Staphlococcus aureus). MRSA is the most common nosocomial infection (infection acquired in the hospital). MRSA enters through cuts and wounds om the skin.
