One of the ways to prevent or slow down the transmission of infectious diseases is to recognize the different characteristics of various diseases. Some critical disease characteristics that should be evaluated include virulence, distance traveled by victims, and level of contagiousness. The human strains of Ebola virus, for example, incapacitate their victims extremely quickly and kill them soon after. As a result, the victims of this disease do not have the opportunity to travel very far from the initial infection zone. Also, this virus must spread through skin lesions or permeable membranes such as the eye. Thus, the initial stage of Ebola is not very contagious since its victims experience only internal hemorrhaging. As a result of the above features, the spread of Ebola is very rapid and usually stays within a relatively confined geographical area. In contrast, the Human Immunodeficiency Virus (HIV) kills its victims very slowly by attacking their immune system. As a result, many of its victims transmit the virus to other individuals before even realizing that they are carrying the disease. Also, the relatively low virulence allows its victims to travel long distances, increasing the likelihood of an epidemic.
Why is the initial stage of Ebola not very contagious?
****
The answer: victims experience only internal hemorrhaging

Nuclear strike is the ability of nuclear forces to rapidly and accurately strike targets which the enemy holds dear in a devastating manner. If a crisis occurs, rapid generation and, if necessary, deployment of nuclear strike capabilities will demonstrate US resolve and may prompt an adversary to alter the course of action deemed threatening to our national interest. Should deterrence fail, the President may authorize a precise, tailored response to terminate the conflict at the lowest possible level and lead to a rapid cessation of hostilities. Post-conflict, regeneration of a credible nuclear deterrent capability will deter further aggression. The Air Force may present a credible force posture in either the Continental United States, within a theater of operations, or both to effectively deter the range of potential adversaries envisioned in the 21st century. This requires the ability to engage targets globally using a variety of methods; therefore, the Air Force should possess the ability to induct, train, assign, educate and exercise individuals and units to rapidly and effectively execute missions that support US NDO objectives. Finally, the Air Force regularly exercises and evaluates all aspects of nuclear operations to ensure high levels of performance.
What is one of the areas where the US Air Force might operate its missions?
****
The answer: Continental United States

The Germans launched a surprise counter offensive, in the Battle of the Bulge in December 1944, which the Allies turned back in early 1945 after Eisenhower repositioned his armies and improved weather allowed the Air Force to engage. German defenses continued to deteriorate on both the eastern front with the Soviets and the western front with the Allies. The British wanted Berlin, but Eisenhower decided it would be a military mistake for him to attack Berlin, and said orders to that effect would have to be explicit. The British backed down, but then wanted Eisenhower to move into Czechoslovakia for political reasons. Washington refused to support Churchill's plan to use Eisenhower's army for political maneuvers against Moscow. The actual division of Germany followed the lines that Roosevelt, Churchill and Stalin had previously agreed upon. The Soviet Red Army captured Berlin in a very large-scale bloody battle, and the Germans finally surrendered on May 7, 1945.
What German city did the British wish to conquer?
****
The answer: Berlin
