Very similar to common cold, influenza or flu mainly when the weather changes. Droplet Precautions Droplet Precautions are recommended in addition to Standard Precautions for resident with infectious agents transmitted by large droplets. As enveloped viruses, they are usually not viable in small droplet-nuclei. Airborne Droplet Aerosol mist or dust containing the pathogen Close contact with an infected individual (1-2m) Particles are suspended in air and travel long distances from their origin Direct contact with a contaminated object (touching) Indirect: Face-to-face contact not needed Improper hand cleaning Sharing food, drinks or eating The microorganisms transmitted by an airborne route may be spread via fine mist, dust, aerosols, or liquids. x�[�r��}�W oЌ$���Kgl����6MF�>4}���JJ\:q���ӽ�Z� %Jt2c��9����l@?�_�?�/^��7�Y����4��/�ۿl/��\m痛�j]�y_��.WXo�y��,�����뺬��������ؖ���g岬J�U����g弬~�_���>�������/b[�&�4^��y�A�D˸r�������[�}��5���R�֛,�MKRM�����g�\���Yi&x�Tگ��Rۜ��.��\��:���.gf�7E�z�^�'����,M���E�:�^�WS4�J��ĝ�M�p��|;A���S佚m�4 �M�����+�*��0�%0~��[Cg���eb Mounting evidence suggests the virus that causes COVID-19 can be airborne, especially in indoor spaces with poor ventilation, although the dose needed to infect someone is unknown.
