Smallpox ( Variola )
Division of Disease Control What Do I Need to Know? Smallpox ( Variola ) What is Smallpox? Smallpox is a serious contagious disease that can be fatal. It is caused by the variola virus, a member of the Poxviridae family. The World Health Organization declared smallpox eliminated from the world in 1980. Who is at risk for Smallpox? Because smallpox has been eliminated, no one will be exposed to a naturally occurring case of smallpox. Smallpox is considered one of the viruses that maybe used in an attack by bioterrorists. Anyone who has not received smallpox vaccine is at risk if exposed to the virus. Also, people who received the vaccine may be at risk if exposed to smallpox because the protection declines five to ten years after one dose and possibly longer after two or more doses. The United States stopped routine childhood vaccination against smallpox in 1972. The last case of smallpox in the United States was in 1949 and the last naturally occurring case occurred in 1977 in Somalia. What are the symptoms of Smallpox? The first stage of the illness lasts two to five days with symptoms that include a high fever of 102˚F – 104˚F, a general feeling of discomfort, severe headache, backache, abdominal pain, and weakness. Most people will be severely ill and bedridden during this stage. By the third or fourth day of this stage, the fever usually drops. Following this stage, soars appear in the mouth and throat, but they may not be noticed by the infected person. The rash begins less than 24 hours after the sores in the mouth and throat appear. -
Vaccinia Belongs to a Family of Viruses That Is Closely Related to the Smallpox Virus
VACCINIA INFECTION What is it? Vaccinia belongs to a family of viruses that is closely related to the smallpox virus. Because of the similarities between the smallpox and vaccinia viruses, the vaccinia virus is used in the smallpox vaccine. When this virus is used as a vaccine, it allows our immune systems to develop immunity against smallpox. The smallpox vaccine does not actually contain smallpox virus and cannot cause smallpox. Vaccination usually prevents smallpox infection for at least ten years. The vaccinia vaccine against smallpox was used to successfully eradicate smallpox from the human population. More recently, this virus has also become of interest due to concerns about smallpox being used as an agent of bioterrorism. How is the virus spread? Vaccinia can be spread by touching the vaccination site before it has fully healed or by touching clothing or bandages that have been contaminated with the live virus during vaccination. In this manner, vaccinia can spread to other parts of the body and to other individuals. It cannot be spread through the air. What are the symptoms of vaccinia? Vaccinia virus symptoms are similar to smallpox, but milder. Vaccinia may cause rash, fever, headache and body aches. In certain individuals, such as those with weak immune systems, the symptoms can be more severe. What are the potential side effects of the vaccinia vaccine for smallpox? Normal reactions are mild and go away without any treatment.These include: Soreness and redness in the arm where the vaccine was given Slightly swollen, sore glands in the armpits Low grade fever One in approximately three people will feel badly enough to miss school, work or recreational activities Trouble sleeping Serious reactions are not very common but can occur in about 1,000 in every 1 million people who are vaccinated for the first time. -
Adult Vaccines
What do flu, whooping cough, measles, shingles and pneumonia have in common? 1 They’re viruses that can make you very sick. 2 Vaccines can help prevent them. Protect yourself and those you care about. Get vaccinated at a network pharmacy near you. • Ask your pharmacist which vaccines are right for you. • Find out if your pharmacist can administer the recommended vaccinations. • Many vaccinations are covered by your plan at participating retail pharmacies. • Don’t forget to present your member ID card to the pharmacist at the time of service! The following vaccines are available and can be administered by pharmacists at participating network pharmacies: • Flu (seasonal influenza) • Meningitis • Travel Vaccines (typhoid, yellow • Tetanus/Diphtheria/Pertussis • Pneumonia fever, etc.) • Hepatitis • Rabies • Childhood Vaccines (MMR, etc.) • Human Papillomavirus (HPV) • Shingles/Zoster See other side for recommended adult vaccinations. The vaccinations you need ALL adults should get vaccinated for1: • Flu, every year. It’s especially important for pregnant women, older adults and people with chronic health conditions. • Tetanus, diphtheria and pertussis (whooping cough). Adults should get a one-time dose of the Tdap vaccine. It’s different from the tetanus vaccine (Td), which is given every 10 years. You may need additional vaccinations depending on your age1: Young adults not yet vaccinated need: Human papillomavirus (HPV) vaccine series (3 doses) if you are: • Female age 26 or younger • Male age 21 or younger • Male age 26 or younger who has sex with men, who is immunocompromised or who has HIV Adults born in the U.S. in 1957 or after need: Measles, mumps, rubella (MMR) vaccine2 Adults should get at least one dose of MMR vaccine, unless they’ve already gotten this vaccine or have immunity to measles, mumps and rubella Adults born in the U.S. -

Malariology Overview History, Lifecycle, Epidemiology, Pathology, and Control David Sullivan, MD Malaria History • 2700 BCE: The Nei Ching (Chinese Canon of Medicine) discussed malaria symptoms and the relationship between fevers and enlarged spleens. • 1550 BCE: The Ebers Papyrus mentions fevers, rigors, splenomegaly, and oil from Balantines tree as mosquito repellent. • 6th century BCE: Cuneiform tablets mention deadly malaria-like fevers affecting Mesopotamia. • Hippocrates from studies in Egypt was first to make connection between nearness of stagnant bodies of water and occurrence of fevers in local population. • Romans also associated marshes with fever and pioneered efforts to drain swamps. • Italian: “aria cattiva” = bad air; “mal aria” = bad air. • French: “paludisme” = rooted in swamp. Cure Before Etiology: Mid 17th Century - Three Theories • PC Garnham relates that following: An earthquake caused destruction in Loxa in which many cinchona trees collapsed and fell into small lake or pond and water became very bitter as to be almost undrinkable. Yet an Indian so thirsty with a violent fever quenched his thirst with this cinchona bark contaminated water and was better in a day or two. -
Smallpox Overview
SMALLPOX FACT SHEET Smallpox Overview The Disease Smallpox is a serious, contagious, and sometimes fatal infectious disease. There is no specific treatment for smallpox disease, and the only prevention is vaccination. The name smallpox is derived from the Latin word for “spotted” and refers to the raised bumps that appear on the face and body of an infected person. There are two clinical forms of smallpox. Variola major is the severe and most common form of smallpox, with a more extensive rash and higher fever. There are four types of variola major smallpox: ordinary (the most frequent type, accounting for 90% or more of cases); modified (mild and occurring in previously vaccinated persons); flat; and hemorrhagic (both rare and very severe). Historically, variola major has an overall fatality rate of about 30%; however, flat and hemorrhagic smallpox usually are fatal. Variola minor is a less common presentation of smallpox, and a much less severe disease, with death rates historically of 1% or less. Smallpox outbreaks have occurred from time to time for thousands of years, but the disease is now eradicated after a successful worldwide vaccination program. The last case of smallpox in the United States was in 1949. The last naturally occurring case in the world was in Somalia in 1977. After the disease was eliminated from the world, routine vaccination against smallpox among the general public was stopped because it was no longer necessary for prevention. Where Smallpox Comes From Smallpox is caused by the variola virus that emerged in human populations thousands of years ago. Except for laboratory stockpiles, the variola virus has been eliminated. -

Malaria: Bad for Business Why Investing in Ending Malaria Provides Some of the Highest Economic Returns
Malaria: Bad for business Why investing in ending malaria provides some of the highest economic returns. Malaria’s burden on the health and wealth of nations While huge progress has been made in recent years, one of the most striking signs of the global impact of the 215 million cases of malaria reported last year is that up to 40% of public health spending goes on the disease in the most heavily affected countries. But malaria reaches far beyond public health, taking its toll on households, local and multinational business profits, and national economic development. Critically, annual economic growth in countries with high malaria transmission has historically been lower than in countries without malaria. In some African countries, malaria reduces GDP growth up to an estimated 1.3%. Malaria costs productivity. Adults are forced to be absent from work, children miss school, and households spend disproportionately on health when they can least afford it. But it need not be this way. With developing countries, donors and private sector firms beginning to take real action, we can be the generation that ends malaria for good and boosts prosperity for all. The economic growth penalty Malaria’s impact on national economies Malaria and poverty occupy common ground. Where the burden of malaria is highest, economic prosperity is lowest. We know that poverty can promote malaria transmission, and that malaria causes poverty by blocking economic growth. Research shows that malaria can strain national economics, having a deleterious impact on some nations’ GDP by as much as an estimated 5 - 6%. It keeps households in poverty, discourages domestic and foreign investment and tourism, affects land use patterns, and reduces productivity through lost work days and diminished job performance. -
Viability of B. Typhosus in Stored Shell Oysters

Measles: Chapter 7.1 Chapter 7: Measles Paul A
VPD Surveillance Manual 7 Measles: Chapter 7.1 Chapter 7: Measles Paul A. Gastanaduy, MD, MPH; Susan B. Redd; Nakia S. Clemmons, MPH; Adria D. Lee, MSPH; Carole J. Hickman, PhD; Paul A. Rota, PhD; Manisha Patel, MD, MS I. Disease Description Measles is an acute viral illness caused by a virus in the family paramyxovirus, genus Morbillivirus. Measles is characterized by a prodrome of fever (as high as 105°F) and malaise, cough, coryza, and conjunctivitis, followed by a maculopapular rash.1 The rash spreads from head to trunk to lower extremities. Measles is usually a mild or moderately severe illness. However, measles can result in complications such as pneumonia, encephalitis, and death. Approximately one case of encephalitis2 and two to three deaths may occur for every 1,000 reported measles cases.3 One rare long-term sequelae of measles virus infection is subacute sclerosing panencephalitis (SSPE), a fatal disease of the central nervous system that generally develops 7–10 years after infection. Among persons who contracted measles during the resurgence in the United States (U.S.) in 1989–1991, the risk of SSPE was estimated to be 7–11 cases/100,000 cases of measles.4 The risk of developing SSPE may be higher when measles occurs prior to the second year of life.4 The average incubation period for measles is 11–12 days,5 and the average interval between exposure and rash onset is 14 days, with a range of 7–21 days.1, 6 Persons with measles are usually considered infectious from four days before until four days after onset of rash with the rash onset being considered as day zero. -
