Answer:

Two independent research studies have shown the benefit of receiving infusions of blood from COVID-19 survivors.

The teams – both based in China – extracted blood plasma from patients who had recovered from COVID-19, which contained antibodies against the disease. The first study from the National Engineering Technology Research Center for Combined Vaccines in Wuhan (uploaded to medRxiv and yet to be peer-reviewed) gave plasma to 10 patients who were severely ill with COVID-19. Six days after receiving the infusion, the COVID-19 virus was undetectable in seven of the 10 patients.

A similar study from Shenzhen Third People’s Hospital treated five ill patients with plasma from survivors. After 10 days three of the patients no longer needed ventilation.

The preliminary findings of this century-old technique come as patients in New York City and Houston have started receiving antibody-loaded plasma. No one really knows whether it will work or not but experts hope this approach will serve as a stop-gap and potentially help them to avoid having to turn away patients from crowded intensive care units. Provided that the blood is properly screened, the advantage of coronavirus-survivor plasma is that it’s readily unavailable, unlike drugs or vaccines which could take months or years to develop.

2. Loss of taste and smell is an important symptom for COVID-19

The latest analysis of data from the COVID Symptom Tracker app suggests a loss of sense of taste and smell may be the best way to tell whether someone has COVID-19.

The app, which was developed by a King’s College London team in association with the Guy’s and St Thomas’ NHS Foundation Trust, NIHR Biomedical Research Centre and a healthcare start-up ZOE Global LTD, asks users to log their symptoms (or lack thereof) daily. By the end of March, 1.8 million users in the UK had signed up to log their symptoms daily.

Between 24-29 March, 26% of the 1.5 million app users reported one or more symptoms; 1,702 of this 26% reported having been tested for COVID-19, with 579 positive results and 1,123 negative results.

In addition, 59% of those patients who tested positive for COVID-19 reported a loss of taste and smell, compared with just 18% of those who tested negative for the disease.

Despite not yet being added to the World Health Organization’s COVID-19 symptom list, lead researcher Tim Spector said: “When combined with other symptoms, people with loss of smell and taste appear to be three times more likely to have contracted COVID-19 according to our data, and should, therefore, self-isolate for seven days to reduce the spread of the disease.”
