In Turkey, improvements in sanitation and the implementation of a vaccination program resulted in reduced rates of childhood exposure to hepatitis A virus. The incidence of symptoms and the complications of the disease are known to be increased in later ages. We aimed to describe changes in the seroprevalence of hepatitis A virus from the pre-vaccine era (2012) to the post-vaccine era (2018) in different age groups. Levels of anti-hepatitis A virus immunoglobulin (Ig)-G of patients with no chronic disease and who were admitted to our hospital between 2013–2018 were obtained retrospectively from a single children’s hospital database system. A total of 3238 subjects were enrolled in the study (2820 children, 418 adults). The overall percentage of seropositivity was 60.5% in group 1 (age ≤2 years), 57.9% in group 2 (age 2–6 years), 31.2% in group 3 (age 7–11 years), 32.7% in group 4 (age 12–18 years), 44.6% in group 5 (age 19–24 years), and 73.9% in group 6 (age >25 years). Between 2013–2018, the increase in the number of seropositive individuals in group 2 (p<0.01), and the decrease in groups 3 and 4 were statistically significant from 2013 to 2018 (p=0.028, p<0.01). According to the data of this single-center children’s hospital in Turkey, hepatitis A virus seropositivity increases significantly in the preschool age group, but decreases in school-age children and adolescents after vaccination.

Çocuklarla ilgili özel bilgi veya görüntülerin, aileleri tarafından veya başka herhangi bir nedenle sosyal medyada paylaşılması ve ifşa edilmesi olguları hızla artmaktadır. Hızlı bir şekilde artan ebeveyn paylaşımları, ‘parenting’ ve ‘share’ kelimelerinden türetilmiş ‘sharenting’ kavramının literatüre girmesine neden olmuştur. İnternette paylaşılan bilgiler çok uzun süre var olma, başkaları tarafından kaydedilip saklanma ve yine başkaları tarafından kullanıma açılma potansiyeline sahiptir. Çocukların rızasının olmadığı ve henüz bilinçli yaşlara gelmedikleri döneme ait görüntülerinin sık kullanılan sosyal medya ağlarında paylaşımı, mahremiyet ihlaline sebep olarak, çocukların istismar tehlikesiyle karşı karşıya kalmalarına yol açabilir.
