WASHINGTON, Feb 17 (Reuters) - U.S. retail sales reboundedsharply in January after households received additional pandemicrelief money from the government, suggesting a pick-up ineconomic activity after being restrained by a fresh wave ofCOVID-19 infections late last year.

The largest gain in retail sales in seven months reported bythe Commerce Department on Wednesday was across the board, andended three straight monthly decreases. The acceleration inactivity at the start of 2021 was evident in other data showingstrong growth in production and prices at factories last month.

Still, the solid economic data did not argue againstPresident Joe Biden's $1.9 trillion recovery plan. Millions ofAmericans remain unemployed. Though COVID-19 infection andhospitalization rates have declined, new strains of the viruspose a risk to the economy fully reopening.

"The economy picked up steam in January and inflation camealong for the ride," said Joel Naroff, chief economist at NaroffEconomics in Holland, Pennsylvania. "Since President Biden isintent on getting a major bill through, look for that to happenand for government money to continue to get into the hands ofhouseholds and businesses."

Retail sales surged by a seasonally adjusted 5.3% last monthafter decreasing 1.0% in December. Economists polled by Reutershad forecast sales increasing 1.1% in January.

Retail sales increased 7.4% from a year ago. Sales lastmonth were led by motor vehicles, with receipts at autodealerships accelerating 3.1%. Sales at clothing stores soared5.0%. Consumers also stepped up spending at restaurants andbars, boosting receipts 6.9%. Still, sales at restaurants andbars were down 16.6% compared to January 2020.

Receipts at electronics and appliance stores powered ahead14.7% and sales at furniture stores surged 12.0%. There werealso hefty increases in sales at sporting goods, hobby, musicalinstrument and book stores.

Receipts at food and beverage stores rose solidly, as didthose at building material stores. Online retail sales jumped11.0% after dropping 7.3% in December.

The government approved another coronavirus rescue packageworth nearly $900 billion at the end of December, which included$600 checks to mostly low-income and some middle-incomeAmericans. The bulk of the money was disbursed in early January,which supported discretionary spending last month.
