Hello and welcome to Healthcare Magic. Thanks for your query.
The recurrent throat and nose problems which you and your family members have been experiencing could be due to an infective cause or an allergic cause. During certain season, especially winters and rainy season, there can be a higher rate of infections. Sometimes, recurrent respiratory symptoms can also be caused due to an allergen like pollen, dust mites, etc.
I would suggest the following measures to prevent further episodes:
1) All family members must follow hygienic precautions when coughing, sneezing
, etc. in order to prevent cross-infection from one person to another.
2) Keep your house free of any possible allergens or irritants. Changing bed sheets regularly to prevent housemites and keeping the house dust-free is important. Avoid exposure to outside dust, smoke and pollution.
3) Eat a nutritious diet with more of vegetables and fruits.
4) You can also take Vitamin C
tablets, which can often be heplful in preventing recurrent respiratory tract
Wish you all the best.
