With a change in season, ailments like viral fevers, chicken pox and vomiting and loose motions have spread in Ghaziabad area. There are at least 100 cases of chicken pox in the area, according to private doctors though officials confirm only about 20 cases. CMO Dr Subodh Kumar has advised people to keep chicken pox patients segregated from the rest of the family in the houses, preferably in a separate room as contact with the patient can spread the illness in the family. Kids between nine-months and one year of age should be given a shot of preventive medicine to protect them from the scourge, CMO said. Cases of chicken pox have been found in localities like Pratap Vihar, Nand Gram, Din Dayal Puri, Kela Bhatta, etc. Awareness about the disease is being increased while medicines are being distributed free among the patients in these localities, he said. All the health centres in the district have the facility for a preventive shot to be given to the people. However, no injection can be given to the patients and the disease is controlled by other methods of medication, CMO advised.
