WHO has studied the Chinese outbreak in detail and reported yesterday the results ā here are some points:
COVID-19 is transmitted via droplets and fomites during close unprotected contact between an infector and infectee. Airborne spread has not been reported for COVID-19 and it is not believed to be a major driver of transmission based on available evidence; however, it canbe envisaged if certain aerosol-generating procedures are conducted in health care facilities.
Fecal shedding has been demonstrated from some patients.
Asymptomatic infection has been reported, but the majority of the relatively rare cases who are asymptomatic on the date of identification/report went on to develop disease. The proportion of truly asymptomatic infections is unclear but appears to be relatively rare and does not appear to be a major driver of transmission.
People with COVID-19 generally develop signs and symptoms, including mild respiratory symptoms and fever, on an average of 5-6 days after infection (mean incubation period 5-6 days, range 1-14 days). Data on individuals aged 18 years old and under suggest that there is a relatively low attack rate in this age group (2.4% of all reported cases).
CONCLUSION
Wash your hands after public exposure, do not exchange handshakes or kisses
Walking around with a mask does not make much sense unless you are going to be in close contact with an active virus shedding patient (nurses, doctors, etc.)
Avoid people that might be contaminated for 2 weeks, make certain to stay away from people that might have the disease.
China has a policy of meticulous case and contact identification for COVID-19. For example, in Wuhan more than 1800 teams of epidemiologists, with a minimum of 5 people/team, are tracing tens of thousands of contacts a day.
Contact follow up is painstaking, with a high percentage of identified close contacts completing medical observation.
Between 1% and 5% of contacts were subsequently laboratory confirmed cases of COVID-19, depending on location.
CONCLUSION
Even when indirect contact with infected people your risk is only 1-5% to get it
Symptoms of COVID-19 are fever (87.9%), dry cough (67.7%), fatigue (38.1%), sputum production (33.4%), shortness of breath (18.6%), sore throat (13.9%), headache (13.6%), myalgia or arthralgia (14.8%), chills (11.4%), nausea or vomiting (5.0%), nasal congestion (4.8%), diarrhea (3.7%), and hemoptysis (0.9%), and conjunctival congestion (0.8%).
Approximately 80% of laboratory confirmed patients have had mild to moderate disease, which includes non-pneumonia and pneumonia cases, 13.8% have severe disease (dyspnea, respiratory frequency ā„30/minute, blood oxygen saturation ā¤93%, PaO2/FiO2 ratio <300, and/or lung infiltrates >50% of the lung field within 24-48 hours) and 6.1% are critical (respiratory failure, septic shock, and/or multiple organ dysfunction/failure). Individuals at highest risk for severe disease and death include people aged over 60 years and those with underlying conditions such as hypertension, diabetes, cardiovascular disease, chronic respiratory disease and cancer. A very small proportion of those aged under 19 years have developed severe (2.5%) or critical disease (0.2%)
CONCLUSION
It looks in more cases like a severe cold with fever.
Differential diagnosis with influenza is not easy (influenza symptoms: fever; aching muscles; chills and sweats; headache; dry, persistent cough; fatigue and weakness; nasal congestion; sore throat)
Young people have low disease rate and mild-moderate symptoms.
Of the 55,924 laboratory confirmed cases have died (3.8%) The overall fatality rate varies by location and intensity of transmission (i.e. 5.8% in Wuhan vs. 0.7% in other areas in China). In China, the overall CFR was higher in the early stages of the outbreak (17.3% for cases with symptom onset from 1-10 January) and has reduced over time to 0.7% for patients with symptom onset after 1 February
Mortality increases with age, with the highest mortality among people over 80 years of age (21.9%). The CFR is higher among males compared to females (4.7% vs. 2.8%).
By occupation, patients who reported being retirees had the highest CFR at 8.9%. While patients who reported no comorbid conditions had a CFR of 1.4%, patients with comorbid conditions had much higher rates: 13.2% for those with cardiovascular disease, 9.2% for diabetes, 8.4% for hypertension, 8.0% for chronic respiratory disease, and 7.6% for cancer .
CONCLUSION
The higher mortality rates at start seem to be explained by lack of good medical treatment.
WHO recommendations for the public as result of the report:
1. Recognize that COVID-19 is a new and concerning disease, but that outbreaks can managed with the right response and that the vast majority of infected people will recover;
2. Begin now to adopt and rigorously practice the most important preventive measures for COVID-19 by frequent hand washing and always covering your mouth and nose when sneezing or coughing;
3. Continually update yourself on COVID-19 and its signs and symptoms (i.e. fever and dry cough), because the strategies and response activities will constantly improve as new information on this disease is accumulating every day; and
4. Be prepared to actively support a response to COVID-19 in a variety of ways including the adoption of more stringent āsocial distancingā practices
