A new study of COVID-19, based on data from a symptom tracker app, determined that there are six distinct "types" of the disease involving different clusters of symptoms. The discovery could potentially open new possibilities for how doctors can better treat individual patients and predict what level of hospital care they would need.
Researchers from King's College London studied data from approximately 1,600 U.K. and U.S. patients who regularly logged their symptoms in the COVID Symptom Tracker App in March and April.
Typically, doctors will look for key symptoms such as cough, fever and loss of the sense of smell to detect COVID-19. The study, which has not been peer-reviewed, says the six different "types" of COVID-19 can vary by severity and come with their own set of symptoms.

Researchers from the Penn Institute of Immunology discovered three distinct immune responses to the SARS-CoV2 infection that could help predict the trajectory of disease in severe COVID-19 patients and may ultimately inform how to best treat them.
The findings were published in Science.
"For patients who are hospitalized with COVID-19, there isn't just one way for the immune system to respond. There's a lot of heterogeneity, which we've distilled down into what we're calling three 'immunotypes,' said senior author E. John Wherry, Ph.D., chair of the department of Systems Pharmacology and Translational Therapeutics and director of the Penn Institute of Immunology in the Perelman School of Medicine at the University of Pennsylvania. "We're hopeful we may actually be able to predict, or at least infer, the different immune patterns a patient has based on clinical data. This would allow us to start thinking about enrolling patients to different types of clinical trials investigating treatments."
The coronavirus triggers different immune responses and symptoms in critically ill patients, but how those two correspond has remained poorly understood, making treatment decisions more difficult.
While recent studies reveal details on the immune's response to the virus, most have been single-case reports or focused on a small group of individuals. This is the first study, to the author's knowledge, to offer up a comprehensive immune profile of a large number of hospitalized patients.

The point of the sub-types is to predict who will require hospitalization and possibly ventilation, and get better a treatment for overall better outcomes. As I understand it, this typology research is completely focused on treatment, so it's separate from vaccine-related research.
