The incubation period for SARS is believed to be short, around three to six days. The speed of international travel does, however, create a risk that cases can rapidly spread around the world.

The primary way that SARS appears to spread is by close person-to-person contact. SARS-CoV is thought to be transmitted most readily by respiratory droplets (droplet spread) produced when an infected person coughs or sneezes. Droplet spread can happen when droplets from the cough or sneeze of an infected person are propelled a short distance (generally up to 3 feet) through the air and deposited on the mucous membranes of the mouth, nose, or eyes of persons who are nearby.

To the best of your humble FAQ author's knowledge, the current speed record for a 'hobby' radio controlled helicopter is just over 100 miles per hour. To get that fast requires extensive modification, so you end up with a helicopter that can go fast but doesn't really run well, emits an ear-splitting roar, doesn't fly well upside-down, and basically can't really do much besides go really fast. The average person's "sport" helicopter is still pretty quick though. See similar questions...

The reasons for such a rapid spread of the epidemic across the country are migration of labour, low literacy level leading to a low level of awareness among potential high risk groups, gender disparities, sexually transmitted infections, reproductive tract infections and social stigma.

Infections causing gastroenteritis can be spread by contaminated food or water or through an infected food handler. Individuals who are symptomatic with gastroenteritis can spread illness to others by touching handrails, elevator buttons, and shared utensils, as well as through direct intimate contact with others while they are ill.

Infected birds shed flu virus in their saliva, nasal secretions, and feces. Susceptible birds become infected when they have contact with contaminated excretions or surfaces that are contaminated with excretions. It is believed that most cases of bird flu infection in humans have resulted from contact with infected poultry or contaminated surfaces. See similar questions...

Sore eyes can spread by contact of contaminated hands with the eyes (hand to eye contact ) or through touching of eyes with hands which got into contact with contaminated surfaces or objects. It can also spread through droplets from a person with sore eyes who also has a runny nose or cough. See similar questions...

Anybody can get MRSA, but MRSA infections are by far more common among persons in hospitals and healthcare facilities. Less often, MRSA can be acquired in the community. It has been associated with recent antibiotic use, sharing contaminated items, having recurrent skin diseases, and living in crowded settings. Outbreaks of MRSA have been reported among participants in contact sports such as wrestling and rugby. See similar questions...
