Seven Warning Signs H1N1 Flu Is Getting Worse
H1N1 flu often gets better with rest, fluids and proper care.
Some people may become sicker instead of improving.
Trouble breathing, chest pain, confusion or extreme weakness are serious warning signs.
Peeing much less than usual can mean the body is dangerously low on fluids.
Repeated vomiting can also cause dehydration.
A fever or cough that returns after getting better may mean a complication has developed.
Older people, young children, pregnant women and people with certain health problems need extra care.
Antibiotics do not treat the flu virus, but a doctor may consider antiviral medicine or other treatment.
Anyone with severe or rapidly worsening symptoms should seek medical help promptly.
Increasing breathlessness, chest pain, severe weakness or confusion may signal serious complications.
Reduced urination and persistent vomiting can indicate dangerous dehydration.
A returning fever or worsening cough after improvement may indicate a secondary infection or pneumonia.
Most people recover within a few days to less than two weeks, though cough and fatigue may last longer.
Older adults, young children, pregnant women and people with chronic conditions face higher complication risks.
