If we read ongoing research, news, news articles, etc different people are writing different opinions on COVID-19 as follows:
1. It has a relation with temperature ( As it grows very fast below 12-16 degree temp)
2. It has a relation with Gender
3. It has a relation with blood group
4. It has a relation with age
5. It has a relation with Social isolation
6. It has a relation with habits like smoking and drinking
7. It has a relation with chronic disease Diabetes, Cancer, BP etc.
These are the above questions which have to be clear from the mind of people.
I will answer your question point-wisre regarding relationship of different factors with transmission or morbidity/mortality od COVID-19 pandemic (caused by Coronavirus named SARS-CoV-2) for which there is wealth of observational and research data available:
1. Temperature: No proven association - Temperatures in certain areas of Middle-East and Central Africa touching 35-40 C, without any significant decrease in the prevalence of the COVID-19.
2. Gender: Males are more commonly and more severely affected with COVID-19 due to sex hormone (Estrogens, progesterone, and Testosterone), ACE2 receptor expression, and other gender related factors (e.g. smoking, and associated diseases)
3. Blood group: In a small study, blood group A was more likely to be associated with severe disease and higher death rate due to COVID-19 compared with B, AB, and O blood groups.
4. Age: Younger adults and children are often asymptomatic or develop minder symptoms, while older adults have severe COVID-19 disease with higher death rates.
5. Social isolation (or social distancing): When applied with hand hygiene, and testing when having symptoms has been the only factor successful in mitigation of the disease severity, spready, and death rate in the COVID-19 pandemic.
6. Smoking and drinking: Any organ involvement by these addictions(Lungs and liver respectively) increases the risk to COVID-19 and death rate.
7. Chronic diseases: Diabetes, hypertension, cancer, and any type of failure (Heart, renal, and respiratory failure) have worse COVID-19 disease and death rate.

Age of course, immunity sure, we don't know certainly about blood, race or ethnically line.
See my questions
Is the Roma population more affected by Covid-19?
Are some racial groups more vulnerable to COVID-19?
