May be now is not the time for social proximity. Social distancing is expected instead. We should be not less than 3 feet away from other people. It is not a sign of arrogance or anything like that, but it is good hygiene.
Heavy droplets from coughs and sneezes are said to be too heavy to float around and they usually fall less than 3 feet away.
Personal cleanliness is of utmost importance now. There is such thing as coughing and sneezing etiquette.
Not shaking hands with anyone we meet is no more a sign of rudeness, but more of playing smart.
If you know that you have fever, cough and flu like illness, please refrain yourselves from going out of the house. Self quarantine yourselves, even from family members.
Having said that, eat more fresh fruits. They contain vitamins that will strengthen your immunity. Get away from the haze and crowded places. If you must go there, wear mask...surgical mask is sufficient, so I was told by a medical doctor.
Do more doa and solah hajat. May Allah swt bless us and keep H1N1 at bay.
