The results of a ballot of the full ICTV membership organized by the Officers, which may include run-off elections, shall be published on the ICTV web site no later than 1 week before the same Plenary Meeting.
- President and Vice-President shall be elected by a vote of the full ICTV membership. They shall be elected for a term of 3 years and may not serve for more than 2 consecutive terms.
- Three Secretaries shall be elected by a vote of the full ICTV membership. They shall be elected for a term of 6 years and may be re-elected.
- Elected Members shall be elected by a vote of the full ICTV membership. They shall be elected for a term of 3 years and may not serve for more than 2 consecutive terms.
- Virus Subcommittee Chairs shall be elected by a vote of the Executive Committee, normally at a meeting preceding the Plenary Meeting. Nominations shall be made to the President and shall be accompanied by an indication that the person is willing to stand for election. Virus Subcommittee Chairs shall be elected for 3 years and may not serve for more than 2 consecutive terms.
- The total number of Elected Members and Virus Subcommittee Chairs shall be 18, with the number in each category determined by the Executive Committee.

- The Executive Committee shall fill positions that are vacant because of resignation, inability to serve or a failure in the normal channels of appointment. Such an interim appointment shall end at the following Plenary Meeting, and time served shall not count towards term limits.
- National Members shall be nominated by Member Societies of the Virology Division of the IUMS. Societies belonging to the IUMS are considered to be Member Societies of the Division if they have Members actively interested in virology. Whenever practicable, each country shall be represented by at least one National Member, and no country shall be represented by more than five National Members. Nominations of virologists as National Members shall not require approval by the ICTV. However, it is the responsibility of a Member Society to inform one of the Secretaries in writing of the selection of their National Member before the Plenary Meeting. National Members shall be appointed for a term of 3 years following the Plenary Meeting. There is no limit to the number of terms that a National Member may serve, but their appointment should be formally reviewed by the appointing National Society every 3 years.
- Life Members shall be nominated by the Executive Committee, normally in recognition of outstanding services to virus taxonomy. Currently serving Executive Committee Members and virologists within 6 months of their retirement from the Executive Committee shall not be eligible for election. Life Members shall be elected by a vote of the full ICTV membership.
- Virologists shall be appointed to Virus Subcommittees by the Virus Subcommittee Chairs and shall not require further approval. These shall include ex officio all Study Group Chairs (see Article 4.5).
4.4 The Finance Subcommittee of the Executive Committee shall consist of the Officers and the Treasurer and shall be chaired by the President. The President shall replace any Officer who cannot serve for good reason by another Executive Committee Member. The Treasurer shall be an Executive Committee Member appointed by the Finance Subcommittee to administer any funds that may be allocated to the ICTV by the Virology Division of the IUMS or other sources.
4.5 Virus Subcommittee Chairs shall form Study Groups to examine the classification of particular groups of viruses and the nomenclature of taxa by appointing Study Group Chairs, who shall be Virus Subcommittee Members. Each Study Group Chair shall appoint Study Group Members. Study Group Members, other than those who are Study Group Chairs or ICTV Members in other capacities, shall not be ICTV Members, but their names shall be published on the ICTV web site to recognize their valuable contribution to virus taxonomy. Study Group Chairs and other Study Group Members shall usually be appointed immediately after the Plenary Meeting and shall serve until the following Plenary Meeting, which is normally a period of 3 years. Except for unusual circumstances, the term of office of Study Group Chairs shall be limited to 2 consecutive periods of 3 years.
5.1 Plenary Meetings of the full ICTV membership shall be held in conjunction with the International Congresses of Virology organized by the IUMS. Executive Committee Meetings shall be held in conjunction with the Congresses as well as at least once between Congresses.
6.1 Taxonomic proposals may be initiated by an individual ICTV Member, a Virus Study Group, or a Virus Subcommittee. In addition, any scientist may submit a taxonomic proposal or suggestion to the appropriate Virus Subcommittee Chair(s) following the procedures described below.
Proposals shall be sent to the appropriate Virus Subcommittee Chair for consideration by that Virus Subcommittee and the appropriate Study Group(s). Proposals shall also be sent for consideration to all Study Groups and Virus Subcommittees whose interests might be affected by the taxonomic or nomenclatural changes proposed. Taxonomic proposals approved by any Virus Subcommittee, usually in consultation with a Study Group, shall be submitted to the Executive Committee by the Virus Subcommittee Chair for approval.

A quorum shall consist of the President or Vice-President and 18 other Members. No Member may vote more than once on any particular proposal. In the event of a tied vote, the proposal shall not be approved.
7.2 Proposals for changes to taxonomy, nomenclature, the ICTV Code (see Article 8) or the ICTV Statutes shall be voted on in two stages: (1) the Executive Committee shall vote either at a meeting or by a ballot organized by the Officers on whether a proposal shall be presented to the ICTV for ratification as specified by Article 6.1, and (2) the full membership of the ICTV shall decide whether to ratify a proposal either at a Plenary Meeting or by a ballot organized by the Officers. Executive Committee decisions shall be made by a simple majority of Members voting. A quorum shall consist of the President or Vice-President, 1 Secretary and 9 other Executive Committee Members. Changes to the ICTV Statutes shall require the additional approval of the Virology Division of the IUMS (see Statute 11).
7.3 Matters of Executive Committee business not directly concerned with changes to taxonomy, nomenclature, the ICTV Code or the ICTV Statutes may be decided by consensus under the President's chairmanship. Any Executive Committee Member may call for a vote on such matters.
