The reality TV star has been sharing updates with fans.
Kim Kardashian West says she is missing her sisters as the family isolates separately during the coronavirus outbreak.
The reality TV star urged fans stay inside and not to ignore warnings about Covid-19.
A state of emergency has been declared in California while according to the most recent figures for Los Angeles County, where Kardashian West lives, 190 people have tested positive for the virus.
While isolating, Kardashian West, 39, said she found a new picture of her with younger sister Kendall Jenner and told fans she was finding the enforced break from her family difficult.
She wrote on Instagram: “I was organising my photos in my phone and found this and miss my sisters but we are all social distancing and staying away from each other all separately self quarantined.
“It’s hard but we have to do this for our safety and for everyone else’s. PLEASE do not ignore the severity of the warnings to stay inside to stop the spread of this virus. We will all get through this! #TogetherApart.”
Earlier, sister Kylie Jenner, 22, told fans her pregnancy had prepared her for staying inside for prolonged periods.
