What we know about acute respiratory infections
Respiratory infections such as colds, influenza and pneumonia affect millions of people around the world each year. ARIs are one of the most common infectious diseases across Europe. Most cases are mild, but some people become very unwell.
What we are not sure about
There is a great deal that we still do not understand about why some people become more unwell than others, including the role of pre-existing health conditions and the effect of in-born abilities to fight infections.
What this study is exploring
This study is looking at acute (recent onset) respiratory (nose, throat and chest) infections, one of the most common infectious diseases across Europe. The primary aim of this study is to identify host and pathogen related determinants of disease severity of ARI. The study recruits adults who visit their GP due to respiratory infections and adults who need hospitalisation for similar infections.
Study design and recruitment
MERMAIDS is a large-scale, international, publically-funded pragmatic, multicentre, prospective observational study being conducted across various European countries concurrently, including in Ireland. Recruitment is taking place in general practices in each participating country from October to April over three years, with a target recruitment of 2,000 patients.
What does participation involve?
Patients presenting with acute respiratory infections at general practices and hospitals involved in the trial who agree to participate in this study will have blood samples and nasopharyngeal swabs taken by a doctor/nurse on the day they are recruited and follow up samples taken on days 2 and 28.
