1. Why do some children have allergic rhinitis all year round?

It is very common for a person to be allergic to many allergens. For example, in people who are allergic to pollen from trees, grasses, and weeds, the disease can last from spring to late fall in temperate climates. And in tropical countries, pollen allergies can cause illness year-round. Because of that, children can suffer from allergic rhinitis all year round.
However, this terminology has changed in recent times, new guidelines on VM control all classify VMs as intermittent or persistent rather than year round and VMs according to season. There are many reasons for this change. One of them is that a year-round allergen does not necessarily cause year-round HFMD, as it depends on the individual exposure and susceptibility, the symptoms of rhinitis may vary. continuously or concentrated at a particular time of the year.
