Other causes are infections with Rota virus, nora virus, bacterial infections like salmonella, staphylococal and streptococcal, Besides parasites

Mesenteric lymphnodes greater than 1 cm r significant . Pain is quite severe in these type of cases disturbing child usual activities . Most common cause is yersinia enterocolitica . Followed by others . Laparoscopic guided lymph node biopsy is most diagnostic . Though not feasible at times .

Nodes with preserved fat hilum indicate benign disease. They're very common in children. Most likely gut infections. Treat with antibiotics. Antispasmodic Good discussion by Raghavendra sir.

Investigate CBC ESR CRP mt xray chest if inconclusive then biopsy HP under usg or CT guided biopsy HP may be nonspecific or Tb lyumphadenitis

R/o abd tb... Since greater than 1cms needs evaluation... Trial of antibiotic can be given for suspician of enterocolitis

Colitis, infection in the bowel,are the probably cause,
