Bangladesh is a country of six seasons and the sessions are very much co-related with natural and environmental changes make the country exceptionally beautiful in the world. But some common seasonal diseases like coldness, flue, cough, chicken pox etc are frequent in monsoon, winter and summer. Those diseases depend on the immune system. Hence an experiment was designed from the end of Patuakhali Science and Technology University, regarding supplementation of Riboflavin and Vitamin-C along with deworming on seasonal sickness of school going children at Madaripur sadar upazila of Bangladesh. The study observed significant variations regarding frequencies of coldness, flue, coughs, chicken pox, skin diseases, dysentery and diarrhoea of School going children due to effect of vitamin supplementation and deworming. After application of Riboflavin, the number affected students was minimum than that of without supplementation. Before deworming process the number of students for coldness, flue, coughs, chicken pox, skin diseases, dysentery and diarrhea was 95, 60, 35, 0, 25, 5 and 15 %, respectively, but after deworming the values were 15, 5, 25, 0, 5, 10 and 5%, respectively.

Key words: Seasonal sickness, deworming, supplementation, Riboflavin, Vitamin-C, children.

Introduction
Rates of malnutrition in Bangladesh are among the highest in the world, with six million children estimated to be chronically undernourished (DHS,2011).The decline in chronic malnutrition seen previously-from 60% in 1997 to 41% in 2011-now appears to be slowing down. Policies and practice in Bangladesh need to have a greater focus on nutrition, at large scale and across different sectors, in order to accelerate progress on tackling the country’s substantial malnutrition burden of 41% stunting and 16% wasting across a population of 156.5 million (UN, 2013). Social protection is a means for states to protect their most vulnerable citizens. Bangladesh’s current social protection system is fragmented and ineffective– in 2010 reaching just 35% of those living below the poverty line (Kidd et al., 2013). As the Government of Bangladesh leads a significant reform of its National Social Security Strategy and develops its 7th Five Year Plan, harnessing the potential of social protection for nutrition is vital. Vitamin-C (ascorbic acid) plays a major role in human metabolism ranging from the synthesis of collagen, carnitine and norepinephrine to a large number of antioxidant activities (Padayatty et al., 2003). Humans are unable to synthesize Vitamin-C and are dependent on dietary sources, mainly fruit and vegetables. Even in high income countries population-based studies have reported blood levels of Vitamin-C in the range indicating deficiency in around 1 in 5 men and 1 in 9 women in low income groups (Cahill et al., 2009). Riboflavin deficiency also most common in developing countries of Asia and Africa. Older adults, alcoholics, and women who take birth control pills are most likely to suffer from riboflavin deficiency mostly. Its deficiency can be related to many developmental abnormalities such as cleft lip and palate, growth retardation, and cardiac disease. Worm infestation is another problem in children from developing countries due to bad hygienic conditions. It is one of the major causes of childhood malnutrition, anaemia, stunted physical and mental growth, psycho-social problems and this along with repeated gastrointestinal and upper respiratory tract infection contributes to high morbidity in children and remains a major cause of high infant and child mortality in our country (Naghashpour et al., 2017). The objective of this experiment is to observe the normal health status of the school children and to compare the effect of supplementation of deworming medicine, Vitamin-C and Riboflavin (vitamin B2) to overcome the seasonal sickness.
