2021 SIRACA Meeting
ACAV Webinar: Emerging SARS-CoV-2 Variants


Check out the work of several ACAV members in this piece produced by Nova by PBS:

A delegation of ACAV members participated in a historic NIH-sponsored meeting in Havana, Cuba on November 28-30, 2016. This scientific conference titled 'Exploring Opportunities for Arbovirus Research Collaboration' was convened to share information about current arbovirus research, recent findings and future research priorities. It responded to a call for such a meeting at Cuba-U.S. leadership meetings where collaboration on arbovirus research was identified as a priority for scientific interaction. As a result of this meeting, the expectation is that Cuban and U.S. Scientists will identify opportunities for the initiation or expansion of arbovirus research collaboration and cooperation. ACAV is always at the forefront of developments and welcomes this initiative.

ACAV Awards

The ACAV presents three awards. The chair of the executive council appoints a nominating committee for each award. Recipients of awards are selected by the executive council. This procedure provides the nominating committee with nominations and documentation from ACAV members.

Please note: To share equally among everyone in our tropmed community, only one ASTMH (including the Subgroups) award, travel award, fellowships and/or medal will be awarded to a single recipient in a given year.

Those who receive a Subgroup research/travel award are not eligible to receive an ASTMH-sponsored fellowship or ASTMH Travel Award.


1. The Dalrymple/Young Award is given every three years to a mid-career investigator who has made outstanding contributions to arbovirology. Those awarded the Dalrymple-Young Award for mid-career scientists in zoonotic virology truly follow two of the outstanding leaders in their field during the second half of the 20th century. Nominator and Nominee must be members of ASTMH and ACAV.

Image Born in Salt Lake City, Utah and raised in Montpelier, Idaho, Joel Dalrymple received his PhD from the University of Utah and spent his career working on arboviruses and arbovirus diseases, first at the Walter Reed Army Institute of Research in Washington, DC, then at the U.S. Army Medical Research Institute for Infectious Diseases at Ft. Detrick, Frederick, Maryland. Joel's research resulted in more than 100 publications, and he was the recipient of more than 30 national and international honors. In 1983, Joel was the recipient of the Bailey K. Ashford Award of the American Society of Tropical Medicine and Hygiene for outstanding contributions to tropical medicine. Read more... 

Born in Sheffield, England, Nat Young came to the U.S. at an early age, but retained a keen interest throughout his life in the land of his birth.

Nat studied medicine at Yale where he received the Parker Prize, given to the student with the "best qualifications for the practice of medicine." he interned at New York Univesity, followed by a year in clinical pathology at Yale-New Haven Medical Center. He pursued both interests intensively throughout his tragically shortened life. Read more...

2. The Richard M. Taylor Award is given every three years to a person who has made outstanding contributions to arbovirology throughout his or her career.

Image Born in Owensboro, Kentucky, Richard Moreland Taylor, MD, PhD, received a medical degree from the University of Michigan and a doctorate degree in public health from Johns Hopkins University. From 1923 to 1945, he served in Europe and South America for the International Health Division of the Rockefeller Foundation. His first assignment was Montpellier, France, where an epidemic of undulant fever (brucellosis) was creating havoc. In 1936 he was sent to Hungary to establish what would become, in his words, "the first influenza listening post". It triggered the groundwork for influenza virology in RF-initiated institutes of hygiene and epidemiology in Eastern Europe. Read more...

3. The Scherer/Hardy Award is given to an outstanding doctoral graduate either before graduation or up to three years post-graduation.


William F. Scherer, 1981 President of ASTMH, was known for his research productivity. He was a pioneer in the field of tissue culture and growth of polio and many other viruses in vitro. He made now classic studies of the epidemiology of Japanese encephalitis in Japan and was a leader in research on Venezuelan encephalitis virus.

Dr. Scherer received his MD from the University of Rochester and had internships in Internal Medicine at Barnes Hospital, Washington University and in Pathology at the Strong Memorial Hospital, University of Rochester. Read more... 


James L. Hardy was a highly respected scientist and teacher at UC Berkeley for 35 years. He was a leader in research on vector-borne viral diseases (arbovirology) and a distinguished professor in the School of Public Health from 1966-1996.

He was born on July 30, 1932 in Fort Benton, Montana. He graduated from the University of Montana in 1954 and stayed there to complete his MA degree in 1956. His thesis was done at the Rocky Mountain Spotted Fever Laboratory, National Institutes of Health in Hamilton, Montana, under the tutelage of Carl Eklund, an early pioneer in research on encephalitis viruses, poliomyelitis and prions. Read more...

Robert E. Shope International Fellowship in Infectious Diseases

Robert E. Shope, MD (1929 – 2004) devoted his career to the study of viruses carried by mosquitoes, ticks and other biting insects. One of the world’s foremost authorities on insect-borne viruses, he discovered and characterized more previously unknown viruses than any other person in history. He was often called a “walking encyclopedia” of viruses, who made major contributions to the understanding of infectious diseases and the promotion of global health. His lifelong contributions to our understanding of arthropod-borne viruses, hemorrhagic fever viruses and the diseases these viruses cause are without equal. Read his full biography here.

The Robert E. Shope International Fellowship in Infectious Diseases provides support for international training opportunities in arbovirology and emerging diseases for those with an MD, DVM, PhD or related doctoral degree. View the fellowship application guidelines.

Annual Meeting Activities

In addition to award presentations, the agenda for each annual meeting includes old and new business, epidemic reports and a symposium on a relevant topic. Prospective symposium topics are discussed by the executive council and solicited from the committee membership, but the final decision on what will be presented is determined by the chairperson.

ACAV Subcommittees

Subcommittees are an important part of the ACAV and are formed when sufficient interest is presented to the executive council by ACAV members. The council reviews proposed subcommittees and decides whether a particular subcommittee is needed. When council approves the formation of a subcommittee, it appoints a chairperson. The subcommittee chairperson, in consultation with the ACAV chairperson, appoints subcommittee members. New subcommittees formalize their objectives and structure. All subcommittees report progress on objectives at the annual meeting to the ACAV.
