  • Can a truly asymptomatic person transmit this infection to others? How

  • often does that occur and to what extent is that driving the current epidemic? My

  • name is Isaac Bogoch and I'm an infectious diseases specialist.

  • Based on a very high-profile study that was recently conducted the report

  • suggested that the virus was transmitted from someone with no symptoms to other

  • people. A person that traveled from China to Germany for a meeting. This person

  • reportedly felt well and then on her return trip back to China, it was

  • reported that she subsequently developed some signs and symptoms suggestive of an

  • infection and indeed this person did test positive for the novel coronavirus.

  • After that people that were close contacts of the traveler from China, who

  • were still in Germany developed some signs and symptoms of infection in it it

  • was found that they too were infected with this coronavirus. After the report

  • came out it seemed to be discovered that people that were involved with the

  • creation of this report actually never spoke with the individual who came down

  • with the infection directly. After some deeper digging it turns out that the

  • individual who flew in from China to Germany indeed had symptoms and it was

  • reported that she had some muscle aches and pains and wasn't feeling that well

  • and was even taking some medications to suppress her fevers. With social media in

  • everybody's palms you know there there always as the potential for the

  • circulation and of course the amplification of misinformation and

  • pseudoscience, so I think it's a good idea to pick a few reputable sources and

  • stick with a few reputable sources. There is certainly is a tremendous need for data

  • and of course high quality data, and this data can certainly help medical and

  • scientific teams prepare to treat patients and it also is helpful for

  • guiding policy and screening programs, treatment programs, prevention programs

  • vaccinations, and treatment programs. So the data is extremely important. I think

  • we just need to be mindful that not all data is created the same and of course

  • there can be some uncertainty with data if mistakes happen that's completely

  • okay we just have to be able to correct them quickly.

  • In general and we're dealing with respiratory infections it's usually the

  • case that people who have symptoms people who are coughing for example are

  • just more likely to transmit the infection from one person to another. I

  • also think we have to remember that symptoms can be very broad, some people

  • can have symptoms and be very very sick. But we're also hearing about people at

  • the much more mild end of the spectrum with symptoms that they don't even need

  • to seek medical care because their symptoms are more of a nuisance rather

  • than requiring hospitalization. One of the concerns is it might be challenging

  • to control an epidemic if people are walking around with mild symptoms

  • transmitting the infection because it's hard to find those individuals. It's hard

  • to identify them and isolate them or prevent them from spreading the

  • infection to others. With emerging data, we'll see what proportion of individuals

  • fall into that category
