Two people have been hospitalized in Ireland over a suspected case of swine flu.

The patients were taken to Wexford General Hospital after showing symptoms of being infected with a strain of H1N1. One of the patients is a pregnant woman, according to an Independent.ie report.

Authorities don’t believe the condition of the patients is life threatening, and they are responding well to treatment.

Pregnant women are more likely to be admitted with a strain of swine flu as there is a greater risk of complications. Generally, swine flu tends to be most dangerous for at-risk groups like the very young, very old, and those with compromised immune systems.

People are advised to get flu vaccinations to prevent coming down with the illness.

Swine flu is a common illness in pig populations. It is very uncommon for it to spread from pigs to humans. People who work with pigs are at most risk of contracting the illness.

A swine flu pandemic struck a few years ago, causing a worldwide panic over the illness before the World Health Organization in August 2010 finally declared it over. Swine flu is particularly troublesome in India, where more than 30,000 cases have been reported and close to 2,000 deaths.

“Most swine influenza viruses (SIVs) do not cause disease in humans,” the WHO says about the disease on their website. “However, some countries have reported cases of human infection with SIVs. Most of these human infections have been mild and the viruses have not spread further to other people. The H1N1 virus that caused the influenza pandemic in 2009-2010, thought to have originated in swine, is an example of an SIV that was able to spread easily among people and also cause disease.”
