Gastrointestinal and respiratory infections are very common during Hajj. People from all over the world bring with them all kinds of
infections, and the unavoidable closeness of the hundreds of thousands
of pilgrims facilitates easy spread of these illnesses. Fatigue, and
lack of sleep from the physically demanding regimen of Hajj rites as
well as the over-enthusiastic exertions in prayers and devotions, lower
one's immunity and resistance, thereby making one more vulnerable to
disease. However, you can take elementary precautions to minimize your
chances of becoming ill, and also to ensure that you will get back on
your feet faster should you get sick. Getting and staying in good
physical shape by regular exercise prior to your departure is a good
first step. You can also carry certain medicines with you for use later.
Carry a reasonable supply of over-the-counter drugs or buy the newly
available Hajj Health Kit.
