The study notes the virus is primarily transmitted through aerosols and droplets caused by infected people sneezing or coughing near another person. The role of contaminated surfaces in the virus' spread is yet to be fully determined, according to the study, but has "been suggested as a potential mode of transmission also reflected by the strong focus on hand-washing by [the World Health Organisation] and national control schemes".

Donald Trump undertakes medical evaluation in post-COVID-19 interview | Sky News AustraliaUS President Donald Trump has undertaken a medical evaluation in his first televised interview since testing positive to COVID-19 last week – proclaiming he’s now “medication-free”.\n\n“I’m not taking any medications as of probably eight hours ago or so, I’m medication free which, frankly, makes me feel good,” President Trump told Fox News contributor Dr Marc Siegel.\n\n“I don’t like medication.”\n\nPresident Trump said he had doctors “all over the White House” who were “watching every corner”. \n\nHe also said he was now feeling “strong” after finishing his treatment.\n\n“I feel really good, I feel very strong, I know a lot of people that have had the COVID, or the China virus as I call it because it came from China, but I feel really, really strong, and a lot of people don’t feel that way sometimes for a while afterwards,” he said.\n\nPresident Trump said last week when he went to Walter Reed National Military Medical Centre, he had a sore throat and “didn’t feel very strong”.\n\n“I didn’t feel very vital, I didn’t feel like the president of the US should feel,” he said.\n\n“The big secret for me was I got there very early, and I think it would’ve gotten a lot worse, one of the doctors said he thought it would’ve gotten a lot worse.\n\n“Even these medications, they’re a lot better if you get them early than if you get them late.\n\n“Going in early is a big factor in my case.”\n\nPresident Trump said he would donate his own plasma “if they want me to do it”.\n\n“I’d love to do it,” he said.
