To understand pandemics, one must not only understand the organism, mode of transmission, the infectious disease curve, and the course of the illnesd; one must also understand transmissibilty and severity of illness. using SARS-CoV-2/COVID-19 address the concepts of influenza and explain how the resulting pandemic unfolded.

Answer 1

Covid 19 and Influenza virus are almost similar. The influenza is a rapid spreading and very fast transmission among public, Corona virus are a large family of zoonotic virus that causes illness ranging from the common cold to severe respiratory disease. Zoonotic means the virus is transmitted from animal to human beings. 2 other recent coronavirus outbreak have been reported that is MERS-CoV of 2012 was found to transmit from dromedary camels to humans. In 2002 SARS-COV was found to transmit from cover cat to humans. The covid 19 is the world wide pandemic with rapid spreading and features.

Covid 19 pandemic is unfolded by 27 viral pneumonia cases in china wuhan on December 2019 It results in wide range of health problems and economic problems. Especially expert team states that covid 19 is occure from bats but in wuhan there is chance to get infection from pangolins. This the outbreak of covid 19.

Influenza Virus is causing respiratory disease , and a wide range of illeness present like asymptomatic or mild to severe disease or death, This transmitted by droplets, contacts and fomites and preventing by maintain hand hygiene and good respiratory etiquette. Speed of transmission is very fast it has a short intervel period of 3 days, Most affected person is children .Mortality rate is less than covid 19.

if the influenza result in a pandemic it will mainly affect the children , then pregnant , older people with other forms of disease. Mortality rate is higher in covid 19 , But in contrast , antiviral vaccine is available for influenza,but this vaccine not effective against Covid 19. To prevent influenza outbreak to take influenza vaccine each year.

so, in influenza mortality and morbidity rate is reducing because it can prevent with vaccine, the main problem comparing to Covid 19 is prevention, still there is no vaccine prevention can present. it increases the rate of affected persons and increased severioty.
