Could the Spanish flu ever return someday?

Answer 1

yes because it could come more than one time and it's a kind of disease which sometimes return.

The real question is not can the spanish flu return, but when.

What is above is not pessimistic, scientists consider this phenomenon as a normal evolution.

Answer 2

In general, no, because the virus is no longer circulating.

Because people have found relatively well-preserved bodies of victims of this strain of influenza, and the genome of the virus has been fully sequenced and published, it is possible that strains re-created in laboratories could be accidentally (or deliberately!) spread into the general population.

Answer 3

The particular strain from 1918-1919 is not considered extant, and researchers have had to resort to exhuming victims to study the strain. Because many humans alive today are descended from survivors of that virus, it is suspected that some natural immunity is present. It is far more likely that one would contract any of the newer strains that appeared in the late 20th century or early 21st century.

The lethality of the Spanish Flu was due to its ability to trigger pneumonia, combined with comparatively limited knowledge about viruses at the time.

Answer 4

Yes, if the same virus strain that caused it surfaces some place in the world, but it is less likely to cause a pandemic like the one in 1918, since we now have effective vaccinations to prevent infection and because we know more now about viruses and flu to help treat and prevent the spread.
