Coronavirus fears continued to punish the stock market on Friday, even though the latest data on the employment situation in the U.S. painted a rosier picture of the national economy than many had expected. Despite strong job creation in February, however, there are reasons to expect that the Covid-19 outbreak could have devastating impacts on future jobs reports.

The headline numbers seemed to indicate a strong, robust economy, with nonfarm payrolls rising by 273,000 jobs and the unemployment rate moving down to 3.5%. However, when you look more closely at some of the numbers, you can see where a likely reversal could cause problems going forward.

1. Leisure and hospitality jobs were up in February but could reverse quickly

One of the strongest job creators during the month of February was the leisure and hospitality industry. The sector created 51,000 jobs in February, with particularly strong performance in the category of food services and drinking establishments like bars, taverns, and saloons. The arts, entertainment, and recreation category also saw more muted gains, with most of the new jobs coming from the amusements, gambling, and recreation industry.

Much of the early impact that we've seen from the coronavirus thus far, however, has centered on the leisure and entertainment industry. Officials have delayed or are contemplating postponements of everything from sporting events and concert performances to trade shows and conventions. Overseas, closures of theme parks, theaters, and other entertainment venues have been widespread and hurt companies like Disney (NYSE:DIS), and it's quite possible that such moves will start happening in the U.S. in the near future. Ensuing layoffs could have a dramatic impact on the employment situation for the industry, and that would take away one of the areas that has been a source of strength, creating 400,000 new jobs in the past year alone.

2. A big hit to air travel is coming

Another area of the economy that's in line to see massive disruptions is the air travel industry. Already, airlines like United Airlines Holdings (NASDAQ:UAL) have cut back on their service, and plans to travel less both domestically and abroad are resulting in reduced flight schedules and calls for airline employees to take voluntary unpaid leave to help their employers cut costs.

Air transportation hasn't been a huge driver of employment gains, creating just 1,700 jobs in February. However, those numbers could go sharply negative in the months to come, and that could produce downward pressure that would hurt the entire jobs picture nationwide. Moreover, similar declines in related areas like scenic and sightseeing transportation, rail transport, and transit and ground passenger transportation could have a domino impact across the transportation sector.

3. Falling energy prices are going to hit the oil patch hard

One of the biggest casualties of the coronavirus economically has been the energy sector. Oil prices have plunged in response to expected reductions in demand stemming from less industrial activity. Oil and gas exploration and production companies are feeling the pinch, as falling oil pushes their balance sheets to the brink and risks massive shutdowns.

Oil and gas workers aren't a huge portion of the economy, but the jobs tend to pay well, and oil and gas extraction produced 1,100 new jobs last month and more than 13,000 over the past year. Many of those jobs could disappear in a prolonged downturn for energy. If that happens, it'll hit certain areas of the country hard, adding even more fuel to a disrupted overall economy.

Keep your eyes on the future

Impacts from the coronavirus haven't yet shown up in the U.S. jobs report, but it's just a matter of time. If the outbreak worsens from here, then investors can expect to start seeing second-order effects ripple out across the U.S. economy, eventually affecting millions of employees in many different professions.
