Duplication in Checkbox selection in RecyclerView

Below is the my code.

holder.followDiseaseCheckBox.setOnClickListener(new View.OnClickListener() {
        @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
        @Override
        public void onClick(View view) {

            if (holder.followDiseaseCheckBox.isChecked()) {

                holder.followDiseaseCheckBox.setChecked(true);

                checkBoxClicked++;
                holder.followDiseaseCheckBox.setChecked(true);
                // for Follow.
                if (isFollowOrUnFollow.equals("FOLLOW")) {

                    ((FollowActivity) context).diseaseListFromAdapter.add(String.valueOf(diseaseMap.get("id")));
                    ((FollowActivity) context).setFollowButton(true);

                }
                // for Unfollow.
                else if (isFollowOrUnFollow.equals("UN_FOLLOW")) {

                    ((FollowTwoActivity) context).unFollowedDiseaseListFromAdapter.add(String.valueOf(diseaseMap.get("id")));
                    ((FollowTwoActivity) context).setUnFollowDiseaseButton(true);
                }


            } else {

                holder.followDiseaseCheckBox.setChecked(false);

                checkBoxClicked--;
                holder.followDiseaseCheckBox.setChecked(false);
                // for Follow.
                if (isFollowOrUnFollow.equals("FOLLOW")) {
                    ((FollowActivity) context).diseaseListFromAdapter.remove(String.valueOf(diseaseMap.get("id")));
                }
                // for Unfollow.
                else if (isFollowOrUnFollow.equals("UN_FOLLOW")) {
                    ((FollowTwoActivity) context).unFollowedDiseaseListFromAdapter.remove(String.valueOf(diseaseMap.get("id")));
                }

                if (checkBoxClicked == 0) {

                    // for Follow.
                    if (isFollowOrUnFollow.equals("FOLLOW")) {
                        ((FollowActivity) context).setFollowButton(false);
                        ((FollowActivity) context).diseaseListFromAdapter.clear();
                    }
                    // for Unfollow.
                    else if (isFollowOrUnFollow.equals("UN_FOLLOW")) {

                        ((FollowTwoActivity) context).setUnFollowDiseaseButton(false);
                        ((FollowTwoActivity) context).unFollowedDiseaseListFromAdapter.clear();
                    }
                }
            }

        }
    });

Problem is When i select a checkbox including that checkbox some other checkbox in the RecyclerView gets checked. But when i check in diseaseListFromAdapter ArrayList item got added properly but checkbox selection are getting duplicated. Ex: If i checked first item checkbox and scroll down 16th items checkbox will also be checked. Unchecking that checkbox will uncheck the first item as well.
