By 10 January, the WHO was already recommending precautions against droplet and contact transmission. In their 14 January press briefing, the WHO warned that human-to-human transmission was a possibility, given that both SARS and MERS are transmissible.

People pointing to the 14 January tweet that discusses "preliminary investigations" not finding "clear evidence" of human-to-human transmission, but not mentioning the WHO's other statements and recommendations from the same time, are just trying to shift blame.
