When a person has a disease, his or her normal body functionsare disrupted. Some diseases, such as diabetes and mostcancers, are not spread from one person to another. But otherdiseases, such as the flu and strep throat, can be spread. Thesediseases are known as infectious diseases. Infectious diseasesare caused by viruses, bacteria, and other agents known aspathogens.

Introduction: Many types of food, especially meat or fresh produce, can be infected with pathogens. Afoodborne disease is spread when people eat or drink infected food or water. One way to avoid these diseasesis to boil drinking water and thoroughly cook meats.

As the latest wave of Covid surges around the globe, we wanted to update our most relevant Gizmo, Disease Spread. The Gizmo has been reformatted to be more user-friendly, the setting has been changed to students in a school, and there is now a mask option to see how masks can slow the spread. Users can now directly control the exact probability of transmission (without masks) and see how the factors of crowding, disease contagiousness, and masking can affect how quickly the disease spreads through the population.

We have also modified the Student Exploration Sheet and Assessment Questions to reflect the changes to the Gizmo, so please be aware that some of the questions and answers may have changed. Even though the subject of disease spread is never a cheerful topic, we hope you enjoy the updated Gizmo.

The epidemic never actually spread significantly beyond East Asia. One of reasons could be differences in genetic composition of East Asians in comparison to other populations. Such explanation was proposed: -and-associated-important-diseases/association-between-hla-gene-polymorphism-and-the-genetic-susceptibility-of-sars-infection. That paper suggested also artificial origin of the virus. Yet later, in 2017, this paper: =10.1371/journal.ppat.1006698, being an effect of titanic work, found natural strains very similar to human SARS-Cov in bats. No identical strain was ever found though, given however high mutation rates it was expected.

Dehydration will not and should not be a problem on board thePrincess Ishtar . There is ten times as much water on boardas is needed for all passengers for a month. However, all watermust be recycled. Water cannot just be emptied out intospace--well, the water can be disposed of but, in order for thePrincess Ishtar to be successful, she must be able tosuccessfully and continuously recycle the used water as her bigsister, the Earth, does. If it can be proven that space coloniescannot effectively do this, then they would constantly need a freshsupply from a source; but a source will not always be available forfuture space colonies. Where MGM (c)1995 hopefully plans to sendtheir future space colonies is a place far from Earth and even intothe far reaches of the solar system. At this distance, gettingwater from Earth or Mars would not be wise. Instead, recyclingwould provide a way out of this crisis. Water will be recycled asit is done on Earth. It will go through an even longer process ofcleaning to avoid any spread of diseases. Water from the toilets,bath, showers, etc. will go to a separate processing region whereit will go through stricter cleaning processes while water from thesinks will go to another sector of the ship where they may gothrough a faster cleansing process. Naturally, the water will losesome of its flavor so natural minerals will also be added to thewater to enhance the flavor. Special tap faucets can be obtainedfor water with no minerals in them. All water will be tested byhighly sensitive equipment and any contaminated water will be sentback through the whole process. There will be no restrictions onwater but there will be a certain point when the water level goesso far down that water may be restricted or even stopped untilunpolluted water levels rise again. The process of recycling stillmust be perfected so that less than a cup of water will be lostevery decade or so. ff782bc1db
