Globally, the number children with blindness is approximately 1.4 million, representing 4% of the global blind population, and an additional 17.5 million are at risk of developing poor vision. [31] Although this number is significantly lower than the number of blind adults, the estimated economic and social burden of blindness for children is ...
Of all the children in the world, about 19 million of them are estimated to be visually impaired or blind. [28] There is evidence that the prevalence of visual impairment or blindness in children is much higher as many studies use data that are at risk bias and miss many children who fall under multiple categories of disadvantage (i.e. female ...
Blood is normally sterile. [1] The presence of bacteria in the blood is termed bacteremia, and the presence of fungi is called fungemia. [2] Minor damage to the skin [3] or mucous membranes, which can occur in situations like toothbrushing or defecation, [4] [5] can introduce bacteria into the bloodstream, but this bacteremia is normally transient and is rarely detected in cultures because the ...

These can be due to prolonged lack of oxygen or obstruction of the respiratory tract, damage to the brain during birth (due to the accidental misuse of forceps, for example) or the baby being born prematurely. These may also be caused due to genetic disorders [4] or accidents. Post-natal disabilities are gained after birth.
Cortical blindness is the total or partial loss of vision in a normal-appearing eye caused by damage to the brain's occipital cortex. [1] Cortical blindness can be acquired or congenital, and may also be transient in certain instances. [2]
Depending upon a person's ABO blood type, the H antigen is converted into either the A antigen, B antigen, or both. If a person has group O blood, the H antigen remains unmodified. Therefore, the H antigen is present more in blood type O and less in blood type AB. Hh antigen system - diagram showing the molecular structure of the ABO(H) antigen ...
