Q: (CNN) -- Two health care workers went to the emergency room with flu-like symptoms after coming into contact with a patient confirmed to have Middle East Respiratory Syndrome, or MERS, officials said Tuesday. The Florida patient represents the second confirmed case of MERS brought into the United States, the Centers for Disease Control and Prevention said Monday. MERS is a mysterious virus that can be fatal, and was first found in the Arabian Peninsula in 2012. One health care worker in Orlando began showing symptoms 72 hours after exposure to the MERS patient but did not meet criteria for admission and was sent home, said Dr. Antonio Crespo, an infectious disease specialist at Dr. P. Phillips Hospital, where the MERS patient is being treated. The health care worker will be monitored and seems to be improving, Crespo said. The other one, whose symptoms began 24 hours after exposure, was admitted to the same hospital, officials said Tuesday at a press conference. "We're just waiting for the results from the testing that was done yesterday to decide about discharge," Crespo said. At-risk workers at home . The two health care workers are among 20 in the Orlando area who may have been exposed to the MERS patient, and they are being tested for the virus, officials said. They were all notified and told to stay home and not work for 14 days, Crespo said. They also should monitor their temperatures and check for possible symptoms such as a cough, sore throat and fever. Five health team members who may be at risk have been identified at Orlando Regional Medical Center and 15 at Dr. P. Phillips Hospital, Crespo said. They were all evaluated for signs and symptoms that would be consistent for MERS. Samples were sent to the state lab for testing, said Dr. Ken Michaels, medical director for occupational health at Orlando Health. "I'm glad to report that I've spoken to most of these team members today. They all report that they're doing great," Michaels said. On the 14th day, everyone involved will be brought back for further testing. Once medically cleared, they can return to work, officials said. Initial testing should be back within the next day or two, Michaels said. MERS: 5 things to know . Two confirmed U.S. cases . The confirmed MERS patient visited Orlando Regional Medical Center on May 5, accompanying another person who was having a medical procedure, officials said. "I think the risk is negligible to those in the waiting room or the radiology area at (Orlando Regional Medical Center)," said Dr. Kevin Sherin of the Florida Department of Health in Orange County. The MERS patient was admitted to Dr. P. Phillips Hospital on May 9. "Before the patient came to the hospital, he was not having a cough," Crespo said. "He was not having respiratory symptoms. So we believe that that makes less risk of transmission to other potential contacts." Officials from the CDC and the Florida Department of Health are investigating the MERS case. During a White House briefing Tuesday, press secretary Jay Carney said President Barack Obama had been briefed on the MERS situation in the United States and that the CDC is taking the lead. The first U.S. case was reported this month in Indiana. That patient was released from a hospital Friday into home isolation, according to state health officials. The Indiana patient was an American health care provider who had been working in Saudi Arabia and was on a planned visit to Indiana to see his family. The Florida patient is also a health care provider who lives and works in Saudi Arabia, said Dr. Anne Schuchat, assistant surgeon general with the U.S. Public Health Service and director of the CDC's National Center for Immunization and Respiratory Diseases. She said that he is not a U.S. citizen and that the Florida case is not linked to the Indiana one. The U.S. Transportation Security Administration will post CDC advisories at more than 20 U.S. airports to alert travelers about the virus. Although there are no recommendations to change travel plans, the signs will advise travelers to the Arabian Peninsula to avoid contact with sick people and wash their hands often. They should contact a doctor if they develop symptoms such as fever, shortness of breath and coughing, the CDC said. "We think it's really critical to avoid overreacting in the community but also avoid under-reacting in the health care environment," Schuchat told CNN. "The reason for the signage is so that we can promptly identify potential cases so that they can be separated from other people." Can SARS lessons prevent a MERS virus outbreak? What is MERS? As of Friday, there have been 538 cases of MERS in 17 countries, including 145 deaths, according to the World Health Organization, Schuchat said. The virus is also known as MERS-CoV since it is a coronavirus, the same group of viruses as the common cold. It attacks the respiratory system, according to the CDC. Symptoms can lead to pneumonia or kidney failure. There is no vaccine or special treatment for MERS. Doctors said they believe the Indiana patient's quick diagnosis and care dramatically increased his chances for getting better. The "risk to the general public remains very low," Schuchat said. In some countries, the virus has spread from person to person, but only in close contact, such as a person who was caring for an ill person. "This virus has not shown the ability to spread easily from person to person in community settings," she said. Out of "an abundance of caution," the CDC has been contacting people who were passengers on the same flights as the two patients with confirmed MERS, Schuchat said. No cases of MERS have been diagnosed as a result of transmission on a plane, the CDC's Dr. Marty Cetron said. The 44-year-old Florida patient traveled on May 1 from Jeddah, Saudi Arabia, to London, then from London to Boston, Boston to Atlanta, and finally Atlanta to Orlando. The man began feeling unwell on the flight from Jeddah, with symptoms including "fever, chills and a slight cough," Schuchat said. Family members of the patient have been tested as well, Crespo said. "The patient has been doing very well," Crespo said. The patient had a low-grade fever of 100.2 on Monday night but has a minimal cough, and he is "in great spirits."

Q: After a weekend of intense investigation, authorities are piecing together more details about Friday's fatal shooting at Los Angeles International Airport, including the suspect's behavior earlier in the week and a warning from his family that may have come minutes too late. Officers sent to check on Paul Ciancia's welfare arrived at his apartment less than an hour after the shooting started, police said Monday. Here is a rundown to get you up to speed: . The suspect . Ciancia, 23, of Los Angeles, is charged with murder of a federal officer and commission of violence in an international airport. He was shot by officers Friday and was in critical condition at Ronald Reagan UCLA Medical Center on Sunday. A source said Ciancia was unable to speak to investigators. Clues about a motive . Attorney General Eric Holder said Monday that more investigation is necessary to uncover a motive for the attack. But a note found on Ciancia indicated that he wanted to kill Transportation Security Administration employees to "instill fear" in what the suspect called the agents' "traitorous minds," FBI Special Agent in Charge David Bowdich said. According to someone who knew Ciancia and his three roommates well, Ciancia began asking for a ride to the airport days before the shooting. He claimed he needed to fly to New Jersey to help his sick father, but he never said what day he needed to leave, the source said. On Friday, Ciancia burst into a roommate's room and demanded a ride to the airport immediately, said the source, who spoke to CNN on the condition of anonymity. The roommate obliged. Investigators don't think the roommate had any idea of Ciancia's plans. The near-save . Around the same time, Ciancia was sending text messages to family members in Pennsville, New Jersey. One suggested that something bad would happen. Although Ciancia has no known history of mental illness, he said in the texts that he was unhappy, and the messages were alarming enough that Ciancia's father decided to call police. "I felt that it was pretty serious. It sounded as if Paul Ciancia in California was thinking about harming himself, so obviously I knew I needed to make a phone call to the LAPD," Pennsville Police Chief Allen Cummings told CNN's Jake Tapper on Monday. Cummings spoke with a lieutenant there, who told him the department was in the middle of responding to a shooting at LAX. "At this point, we weren't connecting the dots," he said. They did later when a reporter called the police chief, asking him to comment on the shooting. Los Angeles Police Department Cmdr. Andy Smith says police were first called to check on Ciancia at 10:06 a.m. Officers arrived at his apartment six minutes later, according to Smith. Ciancia was already gone. The timeline provided Monday by police differed from that offered earlier by Rep. Michael McCaul, R-Texas, chairman of the House Homeland Security Committee. He said police had arrived at Ciancia's apartment about 45 minutes after the suspect had left for the airport. According to the LAPD account, they arrived 52 minutes after the shooting, which began about 9:20 a.m., according to police. It was not immediately clear when Ciancia left for the airport. The attack . About 9:20 a.m. Friday, Ciancia walked up to a Transportation Security Administration checkpoint in Terminal 3. He pulled a .223-caliber assault rifle from a bag and shot TSA officer Gerardo Hernandez "at point-blank range," according to a court document filed by an FBI agent. Ciancia then went up an escalator but returned to shoot Hernandez again, apparently after seeing him move. He continued walking and shooting. Witnesses said he went from person to person, asking, "Are you TSA?" "I just shook my head," traveler Leon Saryan told CNN's Anderson Cooper. "And he kept going." Chaos and terror inside LAX Terminal 3 . The victims . Hernandez, 39, was the first TSA officer to die in the line of duty since the agency was created in 2001. "He took pride in his duty for the American public and for the TSA mission," said his wife, Ana Hernandez. The couple, who married in 1998, have two children. Two other TSA officers -- James Speer, 54, and Tony Grigsby, 36 -- were wounded but were released from the hospital. Grigsby, who was shot in the foot, told reporters Monday he was injured while helping an elderly man move to a safe area. "I turned around and there was a gunman," he said. "Shot me twice." A traveler who was shot in the leg, 29-year-old Brian Ludmer of Lake Forest, Illinois, was in fair condition Sunday. The police response . TSA officers are unarmed. So it was airport police officers who eventually shot Ciancia multiple times in the chest, also striking him in the face and neck. Airport Police Chief Patrick Gannon said the FBI told him that his officers were 60 seconds behind Ciancia. He praised their response, even though he acknowledged that he had moved his officers away from positions inside the checkpoints during the past year. "The threat ... at the airport does not exist behind security at that podium; the threat exists from the curbline on," Gannon said. "So ... we have our people stationed throughout the airport." Holder said Monday that the investigation will include a review of security measures at LAX and other airports. "The responsibility for protecting airport security is not a TSA function but something that I think we need to certainly examine, given what happened in Los Angeles," he said. Travel delays . The incident forced authorities to shut down parts of the airport, evacuate travelers and put a temporary hold on some departures and landings. More than 167,050 airline passengers were affected by the incident Friday as a result of cancellations, delays or diversions to other airports, according to LAX. One airline, JetBlue, temporarily moved its operations to Long Beach Airport. On Saturday, an additional 40 flights were affected, including 30 that were canceled, involving about 4,000 passengers, according to Los Angeles International Airport. According to FlightAware, a flight tracking website, airlines canceled 236 flights into or out of LAX after the incident Friday morning and 27 more Saturday. An additional 919 flights were delayed over the two days, FlightAware said. Some of those cancellations and delays may have been caused by problems other than the shooting, however. The airport was operating normally Monday morning. Suspect's family responds . Ciancia's family, in a statement read Monday afternoon by attorney John Jordan in New Jersey, said they were "shocked and numbed by the tragic events of last Friday." "It is most important for us as a family to express our deep and sincere sympathy to the Hernandez family," the Ciancia family said. "(By) all accounts, Officer Hernandez was an exemplary member of the law enforcement community and a good family man. Our hearts go out to his family and many others who grieve his passing. "We wish to convey, too, our hopes that those who were wounded during this incident will experience quick and full recoveries. We also regret the inconvenience experienced by thousands of travelers as well as the administration and the employees of the Los Angeles airport." The Ciancia family said they would "continue to love and care for" Paul. "We will support him during the difficult times ahead. While we do not mean to minimize the grief and distress experienced by many other families, we hope that the public will understand that this is a very difficult time for our family, too," the family said. What's next? If convicted, Ciancia could face the death penalty or life in prison without parole. The U.S. attorney general would decide whether to pursue a death sentence. TSA Administrator John Pistole said the shooting has prompted a review of security protocol with partner agencies. McCaul said better coordination with local law enforcement could improve security at checkpoints. But the congressman acknowledged that "it's very difficult to stop these types of attacks." "It's almost like an open shopping mall," he said. Opinion: Don't arm the TSA .

Q: (CNN) -- When news broke that six e-mail accounts belonging to members of the Bush family were hacked and some of the contents posted online, reactions ranged from being offended to amusement. Many people objected to the leak of family exchanges reflecting contingency planning for the funeral of President George H.W. Bush. If ever a family deserves privacy, it is when dealing with the death, or impending death, of a loved one. Others seized on the semi-nude bathing self-portraits of President George W. Bush to resume ridicule not seen since he left office. And virtually everyone took the episode as a warning that "this can happen to you." The Bush family email hack comes on the heels of reports of hacking at universities and major newspapers, and it follows urgent government warnings against our fragile cybersecurity defenses. So, do the average users of online e-mail and Web services simply have to assume that hacking will expose their personal messages and photos? Not necessarily. The recent spate of security breaches and the attention focused on them will mean that government and businesses will up their game even more to secure our information infrastructure. But the security reinforcement might take time. In the meantime, people have options to protect their information and themselves. Privacy and data security is a shared responsibility, after all, and users have a role to play. Some Web-based e-mail services like Google's Gmail offer tools to add an extra layer of protection. Gmail offers a two-step verification to add an extra layer of security. Such protection erects a double gate against unwanted interception. Through two-step verification, in addition to user name and password, you enter a code that the e-mail provider will send via text, voice call or on a mobile app. Two-step verification drastically reduces the chances of someone stealing the personal information from your e-mail account because hackers would have to not only get a password and your user name, they would also have to have access to the mobile phone to which the code is sent. And while you are taking steps to secure your e-mail, you would be well-advised to make sure your WiFi connection is secure. Wireless routers are ubiquitous, allowing you to share your internet connection and files around the house. But without securing your router, anyone within range can access the websites you visit and may be able to access your personal information. Securing your WiFi router with a password is an easy step to take, and it is often overlooked. If you want to get a little more technical, take a look at whether the website you are using to transmit information is using HTTPS -- hypertext transfer protocol secure. HTTPS encrypts your data so that it cannot be intercepted during transmission. You will find that your banking transactions almost always will be conducted through the HTTPS protocol. For an extra level of security, check to see if other websites you use offer HTTPS for transmission. So instead of throwing up your hands that Web-based e-mail and online data transfers can never be secure, seek out and use the security tools that already exist. And no matter what your political persuasion, thank the Bush family for the wake-up call. The opinions in this commentary are solely those of Christopher Wolf.
