A pinworm infection is a type of human intestinal worm infection. Pinworms are tiny, narrow worms that are white and less than half an inch long. A pinworm infection, also known as enterobiasis or oxyuriasis, is the most common type of worm infection in humans in the United States. (CDC)
Pinworm infections are easily spread. They are most common in children between the ages of 5 and 10, people who live in institutions, and those who have regular, close contact with individuals in these groups. Pinworm infections can be effectively treated with medication, though reinfection is possible. Serious complications and long-term health effects are rare.Complications from Pinworm Infections
Most people don’t experience serious complications as a result of pinworm infections. Rarely, if the infestation is left untreated:
  • In females, pinworm infections can sometimes cause a urinary tract infection.
  • In females, pinworms can travel from the anus into the vagina, affecting the uterus,fallopian tubes, and other pelvic organs. Vaginitis, endometritis (an inflammation of the uterine lining), or other infections may result.
  • The presence of a significant number of pinworms can cause abdominal pain.
  • Substantial pinworm populations can rob your body of essential nutrients, which can cause weight loss.
Chandarkala nadi.
 
Ascendent  gemini—- 
 
Lagnaat saptamgaye ketu tadishey rahu sayunktey .
Kalatrey sayodhar vayadhi garbh koshey krami mastthaa.
 
meaning if ketu is in 7th in sagitarius since the ascendent is gemini and lord of 7th jupiter is in lagna with rahu ,then the wife of such native may have stomach disorder and she may have worms in her uterus or womb.
Ketu  is considered as krami- Keera ( worm)
Ketu in 5th causes intestinal worm, upsets digestion and ulcers due to mental worry.
Taking this combination ( Rahu +Jupiter and ketu in 7th from them)  in 5 th/11 or 6th/12 th axis you can somewhat find out susceptibility  of worm infested natives.
