RESUMO
The Food and Drug Administration (FDA) is classifying John Cunningham Virus (JCV) serological reagents into class II (special controls). The Agency is classifying the device into class II (special controls) in order to provide a reasonable assurance of safety and effectiveness of the device.

The Food and Drug Administration (FDA) is implementing a direct final rule correcting the regulation classifying herpes simplex virus (HSV) serological assays by removing the reference to HSV serological assays other than type 1 and type 2. When reclassifying this device, FDA mistakenly distinguished between HSV serological assays type 1 and type 2 and all other HSV serological assays. At that time, and today, the only preamendments HSV serological assays which FDA was aware of were type 1 and type 2 and, therefore, the classification of HSV assays other than type 1 and type 2 was incorrect. FDA is correcting the classification of this device to eliminate possible confusion resulting from this error. Elsewhere in this issue of the Federal Register, we are publishing a companion proposed rule under FDA's usual procedure for notice and comment to provide a procedural framework to finalize the rule in the event we receive significant adverse comment and withdraw this direct final rule.

John Brooksby was an outstanding veterinary virologist, who worked at the Animal Virus Disease Research Institute, Pirbright, for 40 years, for 16 of which he was Director of the Institute. He will be remembered for his contributions to the diagnosis of foot-and-mouth disease, for his discovery of four new types, for the classification of subtypes and for fundamental studies of the virus. As Deputy Director and Director he was responsible for programmes on fundamental investigations of foot-and-mouth disease virus and other viruses exotic to the UK and for the application of the results both in the UK and worldwide. His advice on the distribution and the control of foot-and-mouth disease was sought by international organizations and by individual countries and was responsible for reducing the risk of spread of disease.

Fred Brown was a major figure in British and international virology during most of the latter half of the twentieth century. He brought to the subject a rigorous and critical attitude acquired during his early training in chemistry. In addition, he was passionately interested in the practical application of his work and that of others to the prevention and alleviation of disease. He always believed that his research would make a significant contribution to the welfare of agricultural livestock. He is best known for his pioneering work on foot-and-mouth disease virus, the causative agent for the most important disease of domestic livestock globally. However, he also made seminal contributions to the study of many other viruses of veterinary importance.

The Food and Drug Administration (FDA) is classifying Reagents for detection of specific novel influenza A viruses into class II (special controls). Special controls that will apply to the device are the guidance document entitled, "Class II Special Controls Guidance Document: Reagents for Detection of Specific Novel Influenza A Viruses" and limitations of distribution of these reagents. The agency is taking this action in response to a petition submitted under the Federal Food, Drug, and Cosmetic Act (the act) as amended by the Medical Device Amendments of 1976, the Safe Medical Devices Act of 1990, the Food and Drug Administration Modernization Act of 1997, and the Medical Device User Fee and Modernization Act of 2002. The agency is classifying the device into class II (special controls) in order to provide a reasonable assurance of safety and effectiveness of the device. Elsewhere in this issue of the Federal Register, FDA is publishing a notice of availability of a guidance document that is a special control for this device.
