epidemic, pandemic, epidemic

Explanation:

When a disease exists only within the boundaries of a given region or local population we talk of an endemic disease.

Malaria has been until the present a constant threat to communities in Africa. Given the conditions there it is highly likely that sometimes the disease arises even when efforts have in the past tried to eliminate it.

An epidemic situation usually is the outbreak of a disease that turns into an uncontrolled situation and extends in severity usually resulting in many deaths. Since it affects a large number of people governments try to take measures to control the situation and limit its impact but if the outbreak crosses boundaries then a pandemic occurs where most of the world is vulnerable.

The VIH or Aids is the popular pandemic that once was only reported in Africa continent first , then spread to Europe , Asia and elsewhere to be a global risk. Pandemics occur when they are already present worldwide.

Think of the ongoing situation in China with the coronnavirus , and how the situation is worsening to the point that cases in Europe are already being reported. All organized efforts are being done to limit the scope of the epidemic outbreak.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !

the historians cited in the article all agree with one another about the cause of the civil war. despite coming from different backgrounds and cultures, the historians agree that slavery was the root cause of the civil war. the fact that all these historiansgenerally agree with one another makes their shared viewpoints more reliable and valid, especially because the historians have different backgrounds and all work for the well-respected institutions of howard university, clemson university, and the university of colorado.
