The WHO Advisory Committee on Variola Virus research has continued to oversee and report on the research plan.(世衛組織天花病毒研究咨詢委員會一直在監督和報告研究計劃的情況。)

The detection methods for vaccinia virus were developed and provide a base for laboratory diagnosis of variola-related viruses.(所建立的痘苗病毒系列檢測方法，為天花相關病毒的實驗室診斷奠定了基礎。)

In May 1999, the World Health Assembly reaffirmed the decision to destroy all stocks of variola virus, but authorized temporary retention of stocks for research purposes.(1999年5月，世界衛生大會重申了銷毀所有天花病毒儲存的決定，但授權為研究目的暫時保留儲存。)

Variola virus belongs to the genus of orthopoxvirus, and there are some other infectious members, such as Vaccinia virus, cowpox virus, and monkeypox virus.(在正痘病毒屬還有另外幾種病毒對人具有一定的感染性，如痘苗病毒、牛痘病毒和猴痘病毒。)

This research was recommended by the WHO Advisory Committee on Variola Virus research in November 2004, and is intended to develop better medicines, vaccines and diagnostics for smallpox.(這項研究是由世衛組織天花病毒研究咨詢委員會2004年11月建議的，旨在針對天花開發更好的藥物、疫苗和診斷辦法。)

Destroying the remaining stocks of variola is seen by some countries as the final chapter in eradicating the disease to prevent the risk of accidental release.(一些國家認為，銷毀剩余的天花病毒庫存是消除這種疾病以防止意外釋放危險的終章。)

The vaccinia virus is a non-dangerous virus used in the smallpox vaccine because it is related to the variola virus, which is the agent of smallpox.(痘苗病毒使用在牛痘苗時是無害的，因為它與作為傳播天花媒介物的天花病毒相關。)

These include giant cells associated with variola, herpes simplex and parainfluenza.(這些包括有關天花、皰疹以及副流感的巨細胞。)

In 1996, the World Health Assembly recommended that all remaining stocks of smallpox (variola) virus be destroyed.(1996年，世界衛生大會建議銷毀所有剩余的天花病毒儲存。)
