Yes. Even European countries check for viral diseases including filariasis. Hepatitis A cause hepa A; hepatitis B causes hepa B; hepatitis C causes hepa C. Hepatitis is a disease of the liver. Hepatitis leads to cirrhosis (scar in liver) that sometimes leads to liver cancer. The body can eliminated virus of hepatitis A after getting well from an infection. But the body cannot clear virus of hepatitis B and C. So the goal of medication is to reduce the population of hepa B and C virus. Now, there is hepatitis D.
Fortunately, Dr. Arturo V. Estuita, a Filipino cardiologist and chelationist, in his clinical practice in Pasay City, Philippines found that infusion chelation therapy can reduce the population of hepatitis B virus, from millions to a few thousands. This he discovered when he administered chelation therapy on a patient suffering from hepa B. The result obtained from chelation was far better than those obtained from conventional medication. This is good news. Dr. Estuita did not have the opportunity to prolong the treatment of this patient to see if hepatitis B virus could be eliminated. Of course, it was unethical to do the experiment on his patient. Dr. Estuita says it is probable that chelation therapy can also kill hepa C and hepa D virus. He says he will have the opportunity to see that when a patient will come to him for treatment. I have a Hub "A Medical Breakthrough in The Control of Hepatitis B By Chelation Therapy."
