In people with SCD, red blood cells become crescent or \u201csickle\u201d shaped, making it harder for blood to flow properly.<\/p>\n\n\n\n<p>This can lead to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Severe pain episodes (crises)<\/li>\n\n\n\n<li>Frequent infections<\/li>\n\n\n\n<li>Anemia (low blood levels)<\/li>\n\n\n\n<li>Delayed growth in children<\/li>\n\n\n\n<li>Organ damage over time<\/li>\n<\/ul>\n\n\n\n<p>SCD is not contagious.
