My manager has fallen ill as well as 2 coworkers, I feel I am next...
I'll update you if I do fall ill and test positive.

Are you isolating now The Food Scientist? Fingers crossed for your good health.
To add to the discussion on general (not necessarily Covid-19) viral transmission methods, I've found the following:
Inhalation
Virus transmission to humans occurs via inhalation of aerosolized virus-contaminated rodent urine, saliva, and feces, rarely by rodent bites.

Mosquito
JE virus transmission season differs among endemic regions. It is mainly due to numbers and activities of vector mosquitoes. The climate, especially temperature and rainfall, affects the number and activity of vector mosquitoes.

Hanky-panky
Zika virus transmission by sexual intercourse was suggested by Foy et al.16 He described a patient who was infected with Zika virus infection in southeastern Senegal in 2008.

Plants as a vector
Horizontal virus transmission via passive plant “vectors” provides a novel and intriguing way for some viruses of herbivorous insects to enhance their survival and dispersal. Although these insect viruses cannot multiply within plants, they can circulate within the plants on which their insect hosts feed ... The aphid-infecting Cripaviruses Aphid lethal paralysis virus (ALPV) and Rhopalosiphum padi virus (RhPV) both employ this transmission strategy (Bonning and Miller, 2010; D’Arcy et al., 1981; Gildow and D'Arcy, 1990; Liu et al., 2014b; Maina et al., 2017)

Cat saliva (feline leukemia virus)
The virus is transmitted by direct contact between cats, usually via saliva, as shedding in saliva is consistent in persistently infected cats. Therefore, mutual grooming is an important means of transmission.

Contact/Droplet/Aerosol
For respiratory infectious diseases, influenza probably being the most prominent example, three different, mutually non-exclusive, main modes of respiratory pathogen transmission have been identified (Tellier 2006; Brankston et al. 2007). The classification used in the medical literature considers ‘contact’, ‘droplet’ and ‘airborne’ transmission. Contact transmission (be it direct or indirect) arises from contact with pathogen-containing droplets: direct contact transmission refers to physical contact and transfer of pathogens from an infected person to a susceptible, whereas indirect contact transmission refers to contact with fomites and subsequent transport of the pathogen via, for example, hands to the upper region of the respiratory tract (mouth, nose). Droplet transmission occurs via large droplets that are generated by a close expiratory event (coughing, sneezing): they deposit immediately onto a susceptible's mucous membranes. As large droplets gravitationally settle quickly droplet transmission constitutes a transmission mode only for close contact. Airborne transmission (also referred to aerosol transmission) occurs via inhalation of small respiratory droplets (also referred to as ‘droplet nuclei’) that are small enough to remain airborne.
