Let's try not to make more of it than it is. It is a flu like virus. No mega killer like the plague or ebola.
The plague, is caused by a bacterium, Yersinia pestis, that can be treated by several commonly available antibiotics. According to the CDC, the US averages 7 cases a year, with most years having no associated deaths. Transmission is usually confined to the western US and involves infected rodents and fleas. Infection confers immunity.
Ebola is only spread through direct contact with an infected person’s bodily fluids or from infected bats and non-human primates. It tends to burn itself out due to its high mortality. Infection confers immunity.
The flu is a well-studied virus, so much is known about its transmission, mortality and morbidity rates, severity, prevention, and control. There are testing, treatment, and public health processes and structures in place, along with a vaccine.
Covid-19
- Transmission: beyond close contact, unknown; maybe aerosol or fecal/oral
- Role of fomites such as countertops in transmission: unknown
- Limits of virus’ viability in different conditions such as temperature and humidity: unknown
- Mortality rate: 1-2%, maybe?
- Non-human reservoir: “The most likely ecological reservoirs for SARS-CoV-2 are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified.” - WHO
- Ability of clinicians to distinguish mild infection from the common cold or flu without testing: none
- Ability of clinicians to test samples locally: none as the CDC must test all samples
- Most effective and readily available standard(s) of care: unknown
- Efficacy of adjunctive treatment, given with supportive care: unknown
- Efficacy of 14-day quarantine: unknown, but appears to not be 100%
- Understanding of the range of severity in similar individuals: beyond males’ immunity appearing to be less, none aside from guesses about unknown genetic differences
- Long-term outlook for survivors of severe infection: unknown
- Factors that lead to China’s morbidity and mortality rate among healthcare workers: unknown as China refuses to release complete data
- Infection confers immunity: unknown
- Vaccine: none
- Ability of the US healthcare system, businesses, schools, and other major institutions to deal with an epidemic: from what I’ve read, zero
I‘m not stockpiling, panicking, or changing my habits/routine. But if It becomes a community-acquired disease in my region, I will change what I’m doing, especially given all the unknowns and lack of an effective public health response and infrastructure.
