Quiz: Covid 19

The author wrote the first two

paragraphs to

• point out that most COVID-19

  patients make a full recovery

• describe what the COVID-19

  pandemic is and how it

  started

• show how much scientists

  have learned from the

  COVID-19 pandemic

• explain what the World

  Health Organization is

  and how it has dealt with

  COVID-19

How were pandemics long

ago different from today’s

pandemics?

• Pandemics long ago infected

  animals and people, but

  today’s pandemics affect only

  people.

• Pandemics long ago spread

  very easily, but today’s

  pandemics do not spread that

  much.

• Pandemics long ago affected

  millions of people, but today’s

  pandemics affect only a few

  thousand.

• Pandemics long ago were

  caused by bacterial infections,

  but today’s pandemics are

  more often caused by viruses.

Why doesn’t the common cold

cause pandemics?

• It is fairly rare.

• It usually isn’t deadly.

• It occurs only in Australia.

• It usually isn’t contagious.

The map, “COVID-19’s Rapid

Spread Around the World,”

shows

• which countries had the

  largest number of COVID-19

  cases

• how quickly COVID-19 spread

• areas where humans come

  in close contact with animals

  that have COVID-19

• cities with large populations

  that spread COVID-19

What important role has the

World Health Organization

played during the COVID-19

pandemic?

• The organization has tested a

  large number of people with

  the virus.

• The organization has helped

  scientists share information

  about the virus.

• The organization has raised

  the alarm in Wuhan, China,

  about a new disease.

• The organization has trained

  doctors and nurses to watch

  for new diseases.

According to the sidebar,

“COVID-19 and the United

States,” what factors helped

cause the rapid spread of

COVID-19 in the United States?

• untrained doctors, an

  overabundance of infected

  animals, and too much travel

• too many issues with tests,

  lack of mask-wearing, and no

  national strategy

• too many open businesses, a

  lack of essential workers, and

  no lockdown procedures

• unknowledgeable scientists,

  too many sick medical

  professionals, and a lack of

  quarantining

Containment can be described

as

• the actions taken to keep a

  disease from spreading

• the jobs that essential

  workers must continue to do

• the care that doctors and

  nurses give to their patients

• the communication between

  governments and hospitals

Why do scientists work so hard

to discover vaccines during

pandemics?

• Vaccines teach doctors and

  nurses how to care for sick

  patients.

• Vaccines stop the spread of

  a virus by making people

  immune to it.

• Vaccines make it easier for

  scientists to identify new

  diseases quickly.

• Vaccines develop over years in

  order to assure that they are

  effective.

How might testing large

numbers of people right away

help governments control a

pandemic?

• It can help establish who is an

  essential worker needed to

  keep society functioning.

• It can help scientists test their

  vaccines on large groups of

  people to see if they work.

• It can quickly identify who

  is sick so patients can be

  quarantined to prevent the

  spread of disease.

• It can help countries

  communicate with each

  other so scientists can share

  information about the

  disease.

The author wrote the “Working

Together” section to

• describe how pandemics can

  affect all types of people

• illustrate how unpredictable

  a pandemic can be and how

  fast it can spread

• stress how everyone has

  a duty to help during a

  pandemic

• show the importance of

  developing vaccines during

  pandemics
