PROBLEM: HAVANA (Reuters) - With revolutionary leader Fidel Castro dead and his brother Raul vowing to step down as president in 15 months  it will soon be the hour of heir apparent Miguel Diaz-Canel  an advocate for modernizing Cuba's state-run media and abysmal internet access.
 Diaz-Canel  was elevated to the position of first vice-president in 2013  putting  him  next in line for the presidency.
At 56   he  is a relative youngster in the ruling Communist Party's leadership and will need to appeal to younger generations if Cuban communism is to thrive beyond the Castro brothers.
 He  has already established press and internet freedom as signature concerns  a potentially disruptive change in a one-party state that has monopolized the media for nearly 58 years.
Otherwise  however   he  has a much weaker public profile than the Castros and it is not clear what policy changes  he  would push through.
Until now   he  has held to the party line or avoided public comment on key issues such as economic and political reforms or relations with the United States  which were overhauled by Raul Castro and U.S. President Barack Obama over the past two years.
Still  experts say  his  position as heir apparent is solid and that  he  would have to stumble badly for someone else to leapfrog  him  and become the next president in Cuba's arcane system for choosing its leader.
Born after the Castros took power in 1959   Diaz-Canel  is a child of their revolution who rose through the Communist Party by cultivating relationships within the political elite while avoiding the show-boating that ended the careers of other pretenders.
" He  has the advantage of having outlived  his  predecessors (as heir apparent) " Christopher Sabatini  a Cuba expert at Columbia University's School of International and Public Affairs  said on Monday.
 Diaz-Canel  has been careful not to eclipse Raul Castro and is so cautious as to come off as dull and gray   his  public statements largely unmemorable.
" He 's sublimated any ambitions  he  may have had  so the question is what  his  role and power will be among the old guard. Most people try to imagine  him  bridging the new generation and the historic one. That should be challenging " Sabatini said.
That reserved behavior and the government's secretive nature make  Diaz-Canel  largely a mystery to all but Cuba's political elite.
U.S. officials say they know little about  him   and most Cubans outside  his  hometown of Santa Clara know even less.
If  he  does take over in 2018   Diaz-Canel  will be following 59 years of rule by the Castro brothers  one who was gifted with abundant charisma and the other who commanded the absolute respect of top military and political figures.
" He  will be the first civilian president of the revolution and that will require the confidence of the military " said Arturo Lopez Levy  a former political analyst for the Cuban government whose mother taught Diaz-Canel at university.
 Diaz-Canel  chose to pedal.  He  would navigate the provincial capital Santa Clara  vying for space on narrow streets clogged with horse-drawn carts  motorcycle taxis and pedestrians.

PROBLEM: The most common strain of influenza this year is H3N2 (A)  which was covered by this yearâs flu vaccine. While strains can still mutate in individual cases and render the vaccine ineffective for some people  the flu vaccine can also help lessen the severity of illness in some of these cases  said  Dr. Robert Citronberg  infectious disease physician with Advocate Health Care .
At Lutheran General Hospital in Park Ridge   Citronberg  has seen a steady influx of patients with the flu  which presents  itself  with symptoms including high fever  chills  muscle aches and fatigue   he  said.
âPeople who have genuinely true influenza say that they feel like they got run over by a truck â  Citronberg  said.
An anti-viral prescription medication known as Tamiflu is available to both children adults suffering from the flu. Doctors recommend plenty of rest  drinking fluids and staying away from other people  since people with the flu are typically contagious for about seven days   Citronberg  said.

SOLUTION: Flu season hitting earlier with dozens more outbreaks â and more severe symptoms

PROBLEM: American figure skater  Nathan Chen  has rallied from a fiasco of a short program with a historic free skate at the Pyeongchang Olympics that included an unparalleled six completed quadruple jumps.
 Chen  was guaranteed to rocket up the standings with a 297.35 total  perhaps into the top 10.
Vincent Zhou has been overshadowed during the Pyeongchang Olympics by teammates Adam Rippon and Nathan Chen.
But the youngest member of the U.S. figure skating team is smart and funny. And after a terrific short program   he  has a chance to finish in the top 10 at the Winter Games.
The openly gay Adam Rippon has become a media darling  combining excellent skating to help the U.S. win team bronze with an unfiltered approach to interviews.  The talented Nathan Chen  had been tipped as a gold medal favorite until everything went awry during  his  short program.
Together  they had held the spotlight until Zhou landed the first quad lutz in an Olympic event  and put together the best short program of  his  career to briefly take the lead.
 He  wound up 12th among 30 skaters  easily qualifying for the free skate.
American skater  Nathan Chen  is trying to bounce back from a dreadful performance that left  him  well out of medal contention.  His  teammates  Adam Rippon and Vincent Zhou  are also in action.
