What was the causative agent for influenza 1918?

The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.

What type of protein did the 1918 Spanish influenza bind?

The HA of the 1918 virus has only the four conserved avian sites (Reid et al. 1999). Influenza virus infection requires binding of the HA protein to sialic acid receptors on the host cell surface.

What cure was used for the Spanish flu?

The treatment was largely symptomatic, aiming to reduce fever or pain. Aspirin, or acetylsalicylic acid was a common remedy. For secondary pneumonia doses of epinephrin were given. To combat the cyanosis physicians gave oxygen by mask or some injected it under the skin (JAMA, 10/3/1918).

Where did the 1918 Spanish flu originated?

The first confirmed cases originated in the United States. Historian Alfred W. Crosby stated in 2003 that the flu originated in Kansas, and author John M. Barry described a January 1918 outbreak in Haskell County, Kansas, as the point of origin in his 2004 article.

Is Spanish flu the same as bird flu?

Now there’s talk that the 1918 Spanish Flu pandemic, which killed 20 million people worldwide, may have also been a form of bird flu — but one that involved a genetic change in the virus. Two studies may help explain what made the virus so lethal.

Is COVID-19 the worst pandemic of all time?

While the number of fatalities is increasing rapidly, and the true toll of COVID-19 is unlikely to be known for many years, if ever, it is likely to remain lower than in many historical pandemics.

What was the death rate for the 1918 pandemic?

The analysis showed that, at the peak of the 1918 outbreak (October and November of that year), 31,589 people died in New York City, among a population of 5.5 million people, a figure that translates to an incidence rate of 287.17 per 100,000 person-months.

How do epidemics end?

Epidemics end once the diseases become accepted into people’s daily lives and routines, becoming endemic—domesticated—and accepted. Endemic diseases typically lack an overarching narrative because they do not seem to require explanation. More often, they appear as integrated parts of the natural order of things.
