        Due to the imminent danger presented by the rapidly spreading COVID-19, viable prophylactic and therapeutic measures which can be deveioped and applied at the level of the general public are being sought after. This urgent requirement for a solution are reflected on the individual level by an unprecedcnted rise in consumer sales of supplementary nutrients, nutraceutical products and functional foods which were considered to be effective against intluenza and SARS virus, have been on the front burner during this pandemic. 

       Such findings are consistent with Google and Tastewise research which demonstrated there is rising trend for vitamin C, D, zinc, elderberry, rosemary. echinacea, melatonin, phospbatidylserine, collagen, and mushrooms. Although, consumers are seeking to use any functional food that is used self-nedicating theit moods. As data from in vitro studies accumulates, several viable mechanistic targets for combatting COVID-19 are evident. These include those targeting specific elements of the SARS-CoV-2 genome, including the spike protein (S), the RNA-dependent RNA polymerase, the membrane protein (M), the envelope protein
(E), the NTPase/helicase. required for virus budding and SARS-CoV main protease (3CL protease) are gaining popularity to prevent the entrance of CoV into the cells of the hurnan body. 

       Whilst it was initially thought that children were not as susceptible to infection with virulent strains COVID-19, SARS-CoV-2 infection in neonates, infants and children have been reported. The first report of COVID-19 infection in children came from the USA and comprised of a sample of infants and children aged between 2 months and 15 years. Following this, this first incidence of child mortality resulting from COVID-19 came from Iran's North Khorasan province, on March 24, 2020. This received significant attention from global media and heightened interest in the relatively cost-effective and realistic solutions being suggested in the field of pediatric nutrition. In this connection, breastfeeding represents an important prophylactic agent against a host of communicable and non-communicable diseases, and also has well-cstablished therapeutic effects. This message has been clearly communicated by the media and breastfeeding has subsequently been reported to be significantly more popular amongst mothers than in previous years. It is well-known that breastmilk transmits antibodies from the mother and that this confers enhanced immunity against likely microbial exposures to the newly bomn infant. It has recently been shown that secretory immunoglobulin A which constitutes 90% of the immunoglobulins content in breastmilk, plays an important role in the immune response against COVID-19. The importance ce so secretory immunoglobulin A has also been demonstrated in other viral infections, such as infection with the rotavirus； the human immuno-deficiency virus (HIV), the norovirus, the herpes simplex viruses, echoviruses 6 and 9, and polioviruses 1,2 and 3. Finally, there is data to suggest that the risk of viral infection with COVID 19 in infants changes according to the duration of breastfeeding episodes. Short episodes appear to represent a negative independent risk factor for infection and it is in this connection that WHO have issued guidelines for breastfeeding at home and in a hospital setting.

       國中七年級的導師發現彥君寫字細小、扭曲，雖可完成選擇題，但所書寫的造句與作文內容令人難以理解，因此國文考試常常只有十多分；但他的自然知識豐富，為班上的自然小老師，不僅喜歡動手做實驗，也時常觀看與生物有關的知識影片；下課常獨自在學校的生態池進行觀察，畫的動植物素描栩栩如生，參與政府舉辦的全國學生美展得到 第三名。

      由於他成績落差很大，經提報身心障礙鑑定後，鑑輔會研判為學習障礙。但比起學業表現，彥君的家長更希望加強他的人際關係。
