ST. PETERSBURG, FL 鈥� From January to April 2020, as the coronavirus gripped the Sunshine State, nearly 11,500 ships from 75 countries or territories made a stop at one of the 15 ports dotting Florida鈥檚 coast. Their role in spreading the virus 鈥� and the role the maritime industry plays in COVID-19 worldwide 鈥� has been yet another mystery associated with this novel virus. Until now.
A team of scientists will shine a light on the black box thanks to a new grant from 爱爱直播鈥檚 COVID-19 Rapid Response program. The project, called 鈥淐ontact Tracing of Ships and Seaports in Florida,鈥� is projected to last six months and is one of 14 projects funded in .
While the role of air traffic and cruise ships in the transmission of COVID-19 was documented as the pandemic unfolded, the role of maritime transportation was left out.
鈥淲e are excited to be able to gain insight on the relative importance of shipping traffic in the transmission if the SARS-CoV-2 virus,鈥� said Mark Luther, PhD, professor at the 爱爱直播 College of Marine Science.
Luther is leading the program with collaborators Steven Meyers, PhD, also from the College of Marine Science, and Drew Kramer, PhD, from the 爱爱直播 Department of Integrative Biology. 爱爱直播 will also partner with Gatehouse Maritime and , which recently established a vessel tracking center in St. Petersburg. They will provide additional data for the project.
鈥淥ur project will produce one of the first interfaces between maritime traffic data and epidemiological models,鈥� Luther said.
The team will use Florida as a testbed to develop initial methods and models that can be used in a more extensive study covering ports around the United States 鈥� a project that will require additional, more significant funding. The grant from 爱爱直播 provides $20,000 to launch the pilot.
One month of vessel tracks near Florida. Colors indicate vessel type: cargo (red), passenger (green), tanker (blue), and Other (yellow).
The project will involve a more extensive port-call history of the ships that entered
Florida seaports in the first half of 2020. The team will use the ship tracking data
鈥� including number and type of ship, time in port, and estimated number of crew and
passengers 鈥� to build computer models that help to quantify how connected Florida鈥檚
ports are with the global network of ports. They will combine that information with
existing SARS-CoV-2 disease transmission models to help calculate the probability
of a single infected individual from any one given port infecting others at subsequent
port stops.
鈥淢any shipping legs will be long enough that the development of COVID-19 symptoms will lead to notification and control measures,鈥� Luther said, 鈥渂ut no existing analyses have assessed this source of risk in the U.S., particularly in the Caribbean and Atlantic where transit time between ports is relatively short.鈥�
