Here is a “remarkable” difference between COVID-19 and the Spanish flu of 1918



The Corona virus 2020 and the Spanish influenza pandemic of 1918 have many similarities, but differ in one important point.

“A major difference between the Spanish flu and COVID-19 is the age distribution of deaths,” said Deutsche Bank DB.
-0.45%.
“For COVID-19, older people were mostly the worst affected. Young people of working age were also badly affected by the Spanish flu of 1918. In fact, the pneumonia and influenza mortality rate for 25- to 34-year-olds in the United States was more than 50% higher this year than for 65- to 74-year-olds. A remarkable difference from Covid-1

9. “

Francis Yared, global director of interest rate research at Deutsche Bank, said the overall mortality rate, measured by weekly new deaths and new cases, is around a third of the level observed in the second half of April.

“So we have an interesting situation at the moment where rapidly increasing cases in the US slow down reopening (negative), but the mortality rate drops (positive). This could ultimately give us more confidence that we can now live better with the virus, ”said the bank.


During the Spanish flu of 1918, there was not such a big trade-off between business and public health because you had to suppress the virus so that consumers were safer and businesses could work normally.

During the 1918 flu, cities that had taken non-pharmaceutical measures such as social distancing and school closings tended to have better economic outcomes in the medium term, added Deutsche Bank. “This provided historical support for the argument that there was not that much of a trade-off between business and public health because the virus had to be suppressed so consumers were safer and businesses could work normally.”

Around 500 million people, or a third of the world’s population, were infected with the Spanish flu in 1918. It is estimated that 50 million people died worldwide, with around 675,000 people killed in the United States, according to the Centers for Disease Control and Prevention. “It was caused by an H1N1 virus with genes of avian origin,” added the agency.

During the 1918 flu pandemic, mortality was high among people under 5, 20-40, and 65 and older. The high mortality rate among healthy people, including those aged 20 to 40, was a unique feature of this pandemic, ”said the CDC. “Without a vaccine to protect against influenza infections and without antibiotics to treat secondary bacterial infections that can be associated with influenza infections, global control efforts have been limited to non-pharmaceutical interventions.”

COVID-19, the disease caused by the SARS-CoV-2 virus, infected nearly 11.6 million people worldwide on Monday evening and 2.9 million in the United States, adding more than 156,000 confirmed cases from Thursday evening to Sunday evening July 4th Vacation, according to official information compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The disease had claimed at least 538,933 deaths worldwide and 130,312 deaths in the United States

While COVID-19’s progress has slowed in New York, where most cases are still in the US, confirmed cases of coronaviruses have recently risen in nearly 40 states.

Letter from New York:“When I hear an ambulance, I wonder if there is a coronavirus patient there. Are there more emergency calls or do I notice any siren removed? ‘

There are also some similarities between influenza and COVID-19, including their almost identical symptoms: fever, cough, night sweats, body aches, fatigue, and nausea and diarrhea in the most severe cases. Like all viruses, none can be treated with antibiotics. They can both be spread by coughing and sneezing through respiratory droplets, but they come from two different families of viruses – and ongoing research to develop a universal vaccine against influenza shows how difficult influenza viruses and coronaviruses can be.


“The second wave of the Spanish flu of 1918 was even more devastating than the first wave.”

Historians believe that a more virulent strain of influenza appeared during a difficult three months in 1918 and was spread by troops that traveled through Europe during the First World War. “The second wave of Spanish flu in 1918 was even more devastating than the first,” Ravina Kullar, an infectious disease expert at the Infectious Diseases Society of America and an additional faculty member at the University of California at Los Angeles, told MarketWatch. A mutated strain would be a worst-case scenario for a second wave of SARS-CoV-2 this fall or winter.

Although the 1918 pandemic has been associated with Spain forever, this H1N1 strain was previously discovered in Germany, France, the UK and the United States. Similar to the Communist Party’s reaction to the first cases of COVID-19 in Wuhan, China, World War I buried or undermined these reports. “It is important not to consider the deep links between the First World War and the influenza pandemic simply as simultaneous or successive crises, but rather to be more closely intertwined,” wrote historian James Harris in an article about the pandemic.

Doctors and members of the public were immediately shocked at how otherwise strong, healthy people fell victim to the 1918 influenza. Doctors today attribute this to the “cytokine storm”, a process in which the immune system in healthy people reacts so strongly that it hurts the body. A characteristic of some viruses: An increase in the immune cells and their activating compounds (cytokines) effectively turned the body against itself, led to inflammation of the lungs, severe shortness of breath and made the body susceptible to secondary bacterial pneumonia.
