A patient with a severe asthmatic attack may have to go to a gastroenterology ward, for example.

However, some people with asthma may develop a potentially lethal asthmatic attack from inhaling the dust.

Lung infections, after all, are normally blamed for about 80 per cent of serious asthmatic attacks, according to numerous studies.

Once triggered, such reactions may repeat endlessly, causing hundreds or even thousands of asthmatic attacks through a person's life, said the researchers.

The local irritation of these areas can lead to conjunctivitis, itching, tearing, rhinitis, sneezing, asthmatic attacks, bronchitis, and coughing.
