Mail Under Suspicion
In the 19th century, yellow fever outbreaks created fears that letters could carry contagion. To combat this, U.S. post offices used spiked paddles to puncture envelopes, allowing fumigation gases like sulfur dioxide to disinfect the contents.
The Mosquito Connection
In 1900, Walter Reed proved that mosquitoes transmitted yellow fever, not mail or objects. Despite this, the practice of fumigating mail continued into the 20th century due to public pressure during other outbreaks, such as smallpox and influenza.
Modern Parallels
In 2001, anthrax-laced envelopes caused panic, leading to irradiation of mail sent to certain government addresses. During COVID-19, fears reemerged, though studies showed the virus survives only briefly on porous surfaces like paper, easing public concerns.
Safety Prevails
Today, experts affirm that mail poses little risk of disease transmission. Enhanced cleaning in facilities and protective measures for postal workers ensure that letters and packages remain a safe and vital part of everyday life.
