I want to get a flu vaccine, but I heard it is best to get it during flu season in october this year or wait until april next year. Is this correct? (Hac Thien, 45, Da Nang)
Nga, 43, initially thought he had the flu, but a week later experienced shortness of breath and a rapid heart rate. Doctors diagnosed him with pericardial tuberculosis causing effusion.
Coughs caused by pneumonia often persist, worsen progressively, and may include shortness of breath, unlike common cold coughs that typically resolve on their own.
