Symptoms of covid

Has anybody really had a look at the symptoms of Covid 19
The WHO list the following:
fever
dry cough
tiredness

Fever is common to many diseases, dry cough as well ( how dry is dry) and tiredness has to be one of the most common entirely subjective symptoms in the world)

Less common symptoms:
aches and pains (extremely common and subjective, how much, where, measured how?)
sore throat (extremely common and subjective, how much? measured how
diarrhoea(a bit more rare and slightly objective)
conjunctivitis (a bit more rare and slightly objective)
headache (one of the most common and subjective symptoms in the world) 

loss of taste or smell ( a bit more special, but common feature of a cold and very subjective, unmeasurable, food for hypochondria, actually a symptom of zinc deficiency also)
a rash on skin (slightly measurable, but extremely vague and common) , or 
discolouration of fingers or toes (vague, but a bit better than the others)

Serious symptoms:
difficulty breathing or shortness of breath (anxiety symptom)
chest pain or pressure(anxiety symptom)
loss of speech or movement (could be anxiety symptom)

The only thing that makes covid19  different from a flu or a cold is the rt pcr test.

Covid general thoughts

The number that we normal people can use to guide us concerning risk is not the number of deaths pr positive test. We don’t know the percentage tested, we don’t know how reliable the tests are, and we don’t know how many have had Covid 19 and are immune.  But luckily, like you indicate with your graphs, we can know risk of death by nationality. China is a bit over 2 pr million. Right now, Italy has 6820 deaths in 60 million, 113 pr million.  Annual flu deaths in Italy are around 340 pr million. It the numbers doble for Covid 19, we will still be way below normal flu deaths. And most of the people dying from Covid 19 would be the ones most likely to die from the flu, so if we hadn’t started testing for Corona, we might not have noticed anything at all, especially in China, but even in Italy.  A lot of people die every day from all causes, 1700 pr day in Italy, so many die with Corona, not from Corona. Maybe all the Corona deaths would have died anyway. We really don’t know.

Covid positive but sick with almost anything

You test positive for Covid 19. 80% have no symptoms, but the ones who have symptoms may have them because of hundreds of different viruses or other diseases.  Dry cough could be from smoking, allergy, all other corona viruses, all other corona viruses, all airway infections copd etc.  Most communicable diseases have fever and fatigue as symptoms. So we have no idea if the symptoms stem from covid 19 or any other virus respiratory disease since we did not test for the others.  Pneumonia is not a covid symptom, but still people who die with pneumonia are counted as covid 19 victims. Formally it is not correct to say that they died from covid,?just with covid

Only one in 1000 positive tests should be counted as positive.

Covid tests may be 1000 times too sensitive From an article in NYT: "The PCR test amplifies genetic matter from the virus in cycles; the fewer cycles required, the greater the amount of virus, or viral load, in the sample. The greater the viral load, the more likely the patient is to be contagious. This number of amplification cycles needed to find the virus, called the cycle threshold, is never included in the results sent to doctors and coronavirus patients, although it could tell them how infectious the patients are. In three sets of testing data that include cycle thresholds, compiled by officials in Massachusetts, New York and Nevada, up to 90 percent of people testing positive carried barely any virus, a review by The Times found. On Thursday, the United States recorded 45,604 new coronavirus cases, according to a database maintained by The Times. If the rates of contagiousness in Massachusetts and New York were to apply nationwide, then perhaps only 4,500 of
