Strep throat is an infection of the throat and tonsils. GAS bacteria can spread from person to person through contact with respiratory droplets from a person with strep throat. These droplets may be spread when a person with strep throat coughs or sneezes. You may also get the infection if you:. Strep throat is most common in school-age children. Only 10 percent of adults with a sore throat have strep throat.

Prior research has already concluded that two common bacteria that cause colds, ear infections, and strep throat don't often live for long outside the human body, but a new study finds that they can linger a lot longer than previously thought. Your best defense? Well-scrubbed hands. University of Buffalo researchers in New York published a study December 27 in the journal Infection and Immunity that found that Streptococcus pneumoniae and Streptococcus pyogenes can live on surfaces such as toys, books, and cribs for weeks or even months.

How long do bacteria and viruses live outside the body?

Some bacteria 'live for long periods' on toys, books and cribs

Scientists report that bacteria can persist on surfaces, like furniture and toys, significantly longer than previously thought. But a new study disagrees with this conventional wisdom. In a paper published in the January issue of Infection and Immunity , scientists report that bacteria can persist on surfaces, like furniture and toys, significantly longer than previously thought. These findings should make us more cautious about bacteria in the environment since they change our ideas about how these particular bacteria are spread. This is the first paper to directly investigate that these bacteria can survive well on various surfaces, including hands, and potentially spread between individuals. The culprit behind most ear and respiratory tract infections is Streptococcus pneumoniae.

It can cause streptococcal sore throat which is characterized by fever, enlarged tonsils, tonsillar exudate, sensitive cervical lymph nodes and malaise 6 , 9. If untreated, strep throat can last days 9. Scarlet fever pink-red rash and fever as well as impetigo infection of the superficial layers of skin and pneumonia are also caused by this bacterium 3 , 6 , 7 ,

How Long Is Strep Throat Contagious?

Back to Infections. It depends on the type of bacteria or virus, what kind of surface they are on and what the surrounding environment is like, for example, if it's hot, cold, damp or sunny. Many different types of viruses can cause colds. The viruses can sometimes survive on indoor surfaces for more than 7 days. In general, viruses survive for longer on non-porous water resistant surfaces, such as stainless steel and plastics, than porous surfaces, such as fabrics and tissues. Although cold viruses have been shown to survive on surfaces for several days, their ability to cause an infection reduces rapidly and they don't often survive longer than 24 hours.
