The reproduction number, R0 for short, describes how many additional cases of a disease each infected person will cause during their infectious period….How many others will each sick person infect?

Flies can carry diseases such as typhoid fever, cholera, and dysentery. Cockroaches can carry diseases such as Escherichia coli (E. Coli), and Salmonella food poisoning. Rats and mice can carry diseases such as rat-bite fever, leptospirosis, and Salmonella food poisoning.

Many factors affect the incidence of vector-borne diseases. These factors include animals hosting the disease, vectors, and people. Humans can also be vectors for some diseases, such as Tobacco mosaic virus, physically transmitting the virus with their hands from plant to plant.

Ebola virus also can be killed by many common chemical agents. Chemical agents that will kill the virus include bleach, detergents, solvents, alcohols, ammonia, aldehydes, halogens, peracetic acid, peroxides, phenolics, and quaternary ammonium compounds.

There is no evidence that mosquitoes or other insects can transmit Ebola virus. People infected with Ebola aren’t contagious unless they have symptoms. If a person sick with Ebola coughs or sneezes, and saliva or mucus touches another person’s eyes, nose, mouth, or an open cut or wound, these fluids may spread Ebola.

In most cases, people who have completely recovered from EVD do not become reinfected. However, many survivors suffer from health issues after recovery from Ebola.

It was concerning because the outbreak was on the river, in an area where people traveled and traded. But the virus was stopped after three months, and 4,000 vaccinations.

For most people visiting countries in sub-Saharan Africa, the risk of exposure to the Ebola virus is minimal. People most at risk are those who care for infected people, such as aid workers, or those who handle their blood or body fluid, such as hospital workers, laboratory workers and family members.

U.S. adults’ level of concern about Ebola in 2020, by age group. According to a January 2020 survey in the U.S., 30 percent of adults aged 55 to 64 years reported that they are somewhat concerned about Ebola, compared to 20 percent of adults aged 30 to 44 years.

The most effective way to block aerosolized particles is to use either a half-face or a full-face respirator. HCWs still need shoe covers, a full face respirator and latex or nitrile gloves to decrease the risk of Ebola virus contamination.
