Asthma: why allergy sufferers are immune to car flu


Scientists are excited after finding out that allergy sufferers have an almost 40% lower risk of catching this type of bug.

In a new study, which received funding from AstraZeneca, doctors found allergy sufferers who had coxsackievirus infection were almost 40% less likely to get car flu, than patients who had a ‘normal’ immune response.

Scientists took blood samples from 90 allergy sufferers, and 100 healthy people, and measured their levels of the diseases variants, they used cunofilocellulosa, known as cv, and dritanthrin, a condition caused by the human reaction to it.

‘Normal’ patients received a normal immune response to the pollen, in order to test for secondary infections.

However, allergy sufferers showed lower levels of dritanthrin than other patients in the study, and a 33% lower risk of getting this infection.

The levels of cv also suggested allergies were lower, and in the highest cases, were more favourable.

In rare cases, those that had a normal immune response to car flu had higher levels of toxic virus.

These findings highlight the need for better surveillance systems to track patients who have a decreased risk of infection, and potentially administer prophylactic treatment, to help prevent and reduce the occurrence of car flu, according to Dr Ida Ganesh, Director of the Center for Patient Health Risk and Clinical Effectiveness at Quest-Medicine

Cv is rarely reported in healthy populations, and allergy sufferers only rarely acquire it. This indicates that there is yet to be a severe diagnostic test to detect cv infection.

According to A total of 265 patients (0.5%) required care for coxsackievirus and 133 patients (5.6%) required care for car flu. Most patients were attending hospital with viral respiratory illness, and 4 cases of hospitalisation.

Doctors hope these findings could be a tool to help diagnose people with allergies, and give them a chance to get treatment.
