INSTRUCTIONS:  Read the passage and examine the graph.  Answer questions 1-6 on notebook paper and have them ready to turn in on the first day classes at Alpena School District resume.

PANDEMICS

A pandemic is an epidemic occurring on a scale that crosses international boundaries, usually affecting a large number of people.  Pandemics can also occur in important agricultural organisms (livestock, crop plants, fish, tree species) or in other organisms.  A disease or condition is not a pandemic merely because it is widespread or kills many people; it must also be infectious. For instance, cancer is responsible for many deaths but is not considered a pandemic because the disease is not infectious or contagious.

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (SARS-CoV-2) is a new strain that has not been previously identified in humans.

A new coronavirus was first identified in Wuhan, Hubei, China, in late December of 2019, as causing a cluster of cases of an acute respiratory disease, now referred to as coronavirus disease 2019 (COVID-19), which had been identified in December 2019. According to the media report more than 116 countries and territories have been affected, with major outbreaks in central China, Italy, South Korea and Iran. On March 11, 2020, the World Health Organization characterized the spread of COVID-19 as a pandemic.
