Viral transmission barrier for group settings

A method of using a viral transmission barrier to prevent the transmission of airborne viral particles from an infected person to others of a group of at least two people that may include strangers and are sitting in chairs at a table with a perimeter and each having a section of table perimeter before them at a function where masks are not worn, the method comprising the steps of,

• providing a table and chairs for seating a group of at least two people;
• providing a virial barrier for tables with a height and a top surface with a length, a width, and a perimeter configured to accommodate a group of at least two people that may be strangers sitting in chairs at the perimeter and each having at least 24 inches of perimeter before them, the viral transmission barrier comprising,
• multiple vertical side panels having a thickness sufficient to permit the vertical side panel to remain in a vertical position for a time exceeding 24 hours, a top edge, a height configured to extend at least a width of a hand of a sitting person above the head of any person sitting in a chair in front of the table perimeter, a length comprising a first edge that is configured to extend outwardly beyond the perimeter of the table and a second edge, a separation between adjacent vertical side panels of vertical side panels at points where they cross the table perimeter having a length between the points of at least 18 inches (47 centimeters), and each of the vertical side panels is made of a material that is sufficiently non-porous enough to prevent the transmission through the panel thickness of a virion of an airborne virus with a diameter of at least 50 nanometers and is resistant to degradation from exposure to disinfectant fluids,
• a neighboring vertical side panel having a thickness sufficient to permit the neighboring vertical side panel to remain in a vertical position for a time exceeding 24 hours, a top edge, and a height configured to extend at least a width of a hand of a sitting person above the head of any person sitting in a chair in front of the perimeter of the table, and a length, and is made of a material that is sufficiently non-porous enough to prevent the transmission through the panel thickness of a virion of an airborne virus with a diameter of at least 50 nanometers and is resistant to degradation from exposure to disinfectant fluids,
• a releasably attaching element attached to one of the second edges and the neighboring vertical side panel with a seal that is sufficiently tight enough to prevent the passage through the seal of a virion of an airborne virus with a diameter of at least 50 nanometers and that is resistant to degradation from disinfectant fluids, and
• a horizontal ceiling panel completely covering each of the vertical side panels and spaces between them with a single horizontal ceiling panel such that the horizontal ceiling panel has a perimeter that is greater than the table perimeter and the horizontal ceiling panel is releasably attached to the top edge of each of the vertical side panels;
• releasably affixing the viral transmission barrier on top of the table;
• seating people at the table to perform activities that require removal of masks;
• and
• replacing people with other people as tasks are finished.
