Hillary Clinton has put physical distance between herself and her supporters as she continues to recover from pneumonia, nursing herself from inside her Chappaqua, New York, home.

But large, concrete barriers outside the property and Secret Service officers occupying large black SUVs also block gawkers from getting too close.

Onlookers and media can wander down Clinton's road until they reach the concrete structures. They must not, however, park on the street or set foot on the grass. Otherwise, police officers will come to shoo them away.

Today someone sent Clinton flowers, it would seem. A flower delivery truck is pictured pulling up to concrete barriers blocking off Clinton's property from the rest of the street.

Yesterday Clinton's street was also blocked off by orange barriers - they are no longer there, and the Secret Service has not explained why

Plastic orange barriers also blocked off much of the rest of her road during Clinton's first full day inside her home. They had inexplicably disappeared by Tuesday morning.

The Secret Service did not immediately respond to DailyMail.com's request for comment on the matter Tuesday.

It was similarly unable to say how long the concrete structures had been in place and why they were put there. Those semi-permanent barriers have been there for weeks, however.

The former first lady has received Secret Service protection since husband Bill Clinton held the Oval Office. She was also watched by the Diplomatic Security Service when she was secretary of state and performing official duties.

She would have Secret Service protection now even if she were not married to a former president because she is a major party's nominee for the position. Donald Trump also has Secret Service protection, as does his running mate, Mike Pence, and Clinton's vice presidential pick, Tim Kaine.

Press were camped out on the right side of Clinton's street yesterday in the shade. They had to move to the left side of the street Tuesday after the property owner called the police

Where are they going? Two SUVS left Clinton's home Tuesday around 12:00. It was unclear who was inside or where they were going

Trump gained a protective detail at the end of last year after he requested one. So did Republican presidential candidate Ben Carson. Bernie Sanders had a taxpayer-funded security detail, as well, at the height of his campaign this year.

Secret Service officers assigned to the Clintons now sit watch in shifts from vehicles parked behind the concrete barriers in front of her home.

Clinton's street - and the press camped out at the end of it - have drawn extra attention this week from passersby who occasionally slow their cars to take stock of the scene, as well as photos.

At least one neighbor of the Clintons repeatedly called the police on journalists who inadvertently stepped onto their property as they camped out at the end of the former secretary of state's road.

Today, at least four times the ill presidential candidate has received flowers, the arrival of flower delivery trucks indicates.

'Get Better Soon,' the sign says. 'Stronger Together! Hillary!'

Clinton's campaign admitted on Sunday that she contracted pneumonia and was diagnosed two days before by her doctor after the Democratic White House hopeful was filmed stumbling into a vehicle outside a 9/11 memorial ceremony.

She ignored her doctor's advice and kept appointments with her national security advisers and donors on Friday and Saturday.

The 'dizzy' spell, as Clinton is calling it, was brought on by dehydration, her doctor said.

During a call into Anderson Cooper's CNN's program Monday evening Clinton said she kept her illness a secret because she didn't 'think it was going to be that big a deal.'

Clinton could return to the campaign trail - and the media along with her - as early as Thursday, when she's schedule to give a speech in Washington, D.C.

It was, and Clinton was forced to disclose the sickness hours after ditching her press corps and taking her motorcade to daughter Chelsea's home in the middle of what Fox News was reporting as a 'medical episode.'

Later that evening Clinton's campaign came clean about what had happened. A spokesman said Monday that she had no other 'undisclosed' illnesses and promised a release of her medical records soon.

Clinton sat out a West Coast campaign swing this week and sent Bill in her place. He's in California attending fundraisers on her behalf today and will deliver a speech for her in Las Vegas tomorrow.
