Estimating 1-year Mortality

Taking into consideration all causes of death, estimated COVID-19 would cause 18,000 to 588,000 excess deaths in the UK depending how much of the population became infected.

Estimating Maternal & Child Mortality Indirect Impacts

Estimated even the best case scenario for the effects of COVID-19 could indirectly cause over 250,000 child deaths and 12,000 maternal deaths in low and middle income countries. Worst case this could be as high as 1.1 million child deaths and 56,000 maternal deaths.

European Fatality + Demographics

Analysis of 21,522 fatalities in Europe showed 0.1% were below the age of 40. 12.8% were aged 40-69, and 84.8% were 70 years or older.

Italy Patient Details + Outcomes

A sample of 2,653 cases from Italy showed a mean age of 63.2 and a median time from symptom onset to diagnosis of 4 days. 40.5% were hospitalised and of those 37.4% had a comorbidity. 8.1% of cases died and for case that had up to 4 weeks of follow up this was higher. Comorbidities had a stronger association with mortality than with hospitalisation.

Analysing transmission in China outside Hubei

Time to hospitalisation after symptom onset decreased from 4.4 days to 2.6 days as people became more familiar with the outbreak. The average time someone showed symptoms was 5.2 days. It took and estimated 3 weeks for China to get the disease below R1

WHO notes on Asymptomatic vs Pre-Symptomatic cases

There are few reports of laboratory confirmed cases who are truly asymptomatic. To date there has been no documented asymptomatic transmission. This doesn't mean that it isn't occurring.

Average time till death after showing symptoms was 17.8 days and till hospital discharge 24.7 days. Crude fatality rate for China is estimated at 3.67% however after further adjustments and analysis the best estimate is 1.38%. Older age groups showed much higher fatality rates. Infection fatality ratio was estimated at 0.66%. Estimates of infected individuals likely to be hospitalised increased with age up 18.4%.

Early estimates on COVID-19 transmission and control

Estimate that the R0 for COVID-19 in China was 2.35 before travel restrictions and then moved down to 1.05 one week after. Estimated that once there was at least four independently introduced cases there was more than a 50% chance the infection will establish within that population.

Analysing mortality risk factors

Old people more vulnerable. People with comorbidities more likely to be hospitalised and result in fatalities. Average shedding of the virus for survivors was 20 days and COVID-19 was detectable until death in non-survivors. The longest observed viral shedding was 37 days. Viral shedding is associated with being infectious to others.

WHO Report from Feb 16-24 Mission

WHO Report comes out with their initial epidemiological findings. Median age 51 years. R0 estimated at 2-2.5. Only 2.4% of cases below 18 years of age. Symptoms are said to be Fever and  Cough 87.9% and 67.7% of cases. Cases becomes symptomatic 5-6 days from infection. Approximately 80% have a mild disease, 13.8% severe and 6.1% critical. Whilst asymptomatic cases were reported the majority then went on to develop disease. True asymptomatic cases appears rare. Those above 60 years old and with comorbidities at risk. Fatality rate was 3.8% but varies by location. 5.8% in Wuhan and 0.7% in other parts of China. Mortality varied with age. 80 years 21.9%. Median time nationally from symptom onset to case confirmation came down from 12 days to 3 days by early Feb.  

Analysing feasibility of controlling COVID-19

The more infectious a disease the more important it is to contact trace and isolate. The delay between when a person notices symptoms and then how quickly they isolate made one of the biggest differences.
