Which of the following diseases is correctly matched with the way in which it is transmitted? Legionnaires' disease: Waterborne Dengue virus: Water-based Cholera disease: Water-washed Malaria: Water-related Question 2 (0.5 points) How do changes in climate impact the incidence of Cholera? Copepods thrive in high-salinity waters, allowing for increased reservoirs for Vibrio bacteria Cooler temperatures increase fecal-oral transmission of V. cholerae Vibro bacteria growth increases in warm marine and estuarine waters with low salinity Drought allows V. cholerae to thrive and develop new, deadlier, serotypes Question 3 ( 0.5 points) Which of the following areas are projected to have the highest water stress in 2030 ? Libya Southern China Pakistan Southeastern US Luestion 4 (0.5 points) Which of the following is the best definition of safely managed sanitation? Improved sanitation facilities that are not shared with other households and where excreta are safely disposed of and/or treated offsite A series of practices performed to preserve health, including access to facilities for handwashing with improved water and soap Drinking water from an improved source such as piped water, wells, springs, and packaged/delivered water, provided collection time is not more than 30 minutes for a round trip Improved sources of freshwater for human use that is sufficiently free from biological, chemical, radiological or physical impurities such that individuals will not be exposed to disease or harmful physiological effects Which of the following is NOT one of the impacts of climate change on the growth of harmful algal blooms (HABs)? Greater ocean acidification can increase algal growth Warmer ocean temperatures can increase growth of blooms Less CO2 dissolved in the ocean can increase algal growth Increased precipitation can cause runoff that increases growth of HABs.

1. Which of the following diseases is correctly matched with the way in which it is transmitted?
Legionnaires' disease: Waterborne Dengue virus: Water-based Cholera disease: Water-washed
Malaria: Water-related
Question 2 (0.5 points) How do changes in climate impact the incidence of Cholera? Copepods
thrive in high-salinity waters, allowing for increased reservoirs for Vibrio bacteria Cooler
temperatures increase fecal-oral transmission of V. cholerae Vibro bacteria growth increases in
warm marine and estuarine waters with low salinity Drought allows V. cholerae to thrive and
develop new, deadlier, serotypes Question 3 ( 0.5 points) Which of the following areas are
projected to have the highest water stress in 2030 ? Libya Southern China Pakistan Southeastern
US
Luestion 4 (0.5 points) Which of the following is the best definition of safely managed
sanitation? Improved sanitation facilities that are not shared with other households and where
excreta are safely disposed of and/or treated offsite A series of practices performed to preserve
health, including access to facilities for handwashing with improved water and soap Drinking
water from an improved source such as piped water, wells, springs, and packaged/delivered
water, provided collection time is not more than 30 minutes for a round trip Improved sources of
freshwater for human use that is sufficiently free from biological, chemical, radiological or
physical impurities such that individuals will not be exposed to disease or harmful physiological
effects
Which of the following is NOT one of the impacts of climate change on the growth of harmful
algal blooms (HABs)? Greater ocean acidification can increase algal growth Warmer ocean
temperatures can increase growth of blooms Less CO2 dissolved in the ocean can increase algal
growth Increased precipitation can cause runoff that increases growth of HABs
