What are the properties of a single-exposure, common-vehicle foodborne outbreak?

Answer and explanation;

-Common-vehicle exposure  is an outbreak occurs in the group of people who have eaten the food. single exposure  is when food may be served only once, for example, at a catered luncheon.

-Properties of a single-exposure, common-vehicle food borne outbreak includes;

-Such outbreaks are explosive; there is a sudden and rapid increase in the number of cases of a disease in a population.

-The cases are limited to people who share the common exposure. This is self-evident, because in the first wave of cases we would not expect the disease to develop in people who were not exposed unless there were another source of the disease in the community.

-In a food-borne outbreak, cases rarely occur in persons who acquire the disease from a primary case. The reason for the relative rarity of such secondary cases in this type of outbreak is not well understood.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
