Rubella Virus(RuV) is a contagious respiratory infection, and it’s best know as is red rash. It’s also called German Measles or Three- Day Measles. This Infection may cause mild or no symptoms is most people, but it can cause serious problems for unborn babies, whose mothers become infected during pregnancy. Rubella isn’t the same as measles, but the two illnesses share some signs and symptoms, such as the Red Rash.Rubella is caused by a different Virus than Measles, and Rubella isn’t Infectious or Severe as Measles. The Measles -Mumps-Rubella Vaccine is safe and highly effective in preventing rubella, The vaccine provides lifelong protection against rubella. In many countries, rubella infection is rare or even no existent, so because the vaccine isn’t used everyone,the virus still causes serious problems.The symptoms and signs of rubella are often difficult to notice especially in children they appear between two and three weeks aster exposure to the virus. Mild fever of 102 or lower, Headaches,Stuffy or Running Nose,Red,Itchy Eyes, Enlarge, tender Lymph Nodes at the back of the Skull, back of the Neck and behind the Ears,Aching Joints, especially in young Women, it can be Transmitted person to person, when you Sneeze and Cough, it can also be Transmitted when you have Direct Contact with Mucus from the Nose and Throat. Complications that you may have with Rubella are Arthritis in the fingers, Wrist and Knees it last about one month, In rare cases Rubella can cause an Ear Infection or Inflammation of the Brain, if you are Infected and pass it to your Unborn it can be sometimes Fatal for the baby, during the first 12 weeks of pregnancy your unborn can develop growth delay, Cataracts,Deafness,problems with the development of the Heart,problems with the development of the Organs,problems with Mental Development and Learning. A way that we can prevent this is by vaccination getting (MMR)and (MMRV).

Treponema pallidum is a bacterium that can cause numerous diseases due to its various subspecies. Syphilis, bejel, and yaws are three diseases caused by Treponema pallidum. Syphilis is the most well-known association with this bacterium. T. pallidum occurs when penetrating the host, usually through mucous membranes. (Fantry and Tramont, 2017) Simply touching an infected sore or sharing items such as sex toys or razors can transmit this disease. All the body’s organs can be invaded, but research shows that the skin, lymph nodes, and the central nervous system are the sites that are most often invaded. (Fantry and Tramont, 2017) T. Pallidum is found throughout the dermis and was discovered there from abnormal laboratory tests and direct cultures. (Fantry and Tramont, 2017) Late stage of this disease is severe due to invasion of the aorta and/or the arteries of the central nervous system. (Fantry and Tramont, 2017) As for virulence factors, T. pallidum does not reveal any that could account for syphilis signs and symptoms. T. pallidum lacks lipopolysaccharide, the endotoxin found in the outer membranes of many gram-negative bacteria that causes fever and inflammation. (Lafond and Lukehart, 2006) Into the discussion on the sequalae of the infection, in patients with acquired syphilis, there is an initial genital tract lesion (primary stage) followed by dispersed lesions (secondary stage) and, in approximately one-third of untreated individuals, cardiovascular and neurologic problems (tertiary stage). (Radolf, 1996) The non-sexually transmitted versions of T. pallidum include yaws, pinta, and endemic syphilis present as mucous or skin lesions. Soft tissue and bone lesions can also occur with yaws and endemic syphilis. (Fantry and Tramont, 2017) While it can become confusing to understand all these versions of T. pallidum, in summary they vary in symptoms. Bejel symptoms are mucous membrane and cutaneous lesions, followed by bone and skin swelling in the connective tissue of the liver, brain, testes, and heart. Yaws causes periostitis and dermal lesions. Pinta causes lesions that are confined to the dermis. (Bush and Vasquez-Pertejo, 2020) With T. pallidum so easily spread, it is important to take preventative measures to avoid contact with this bacterium. Abstaining from unprotected sex and avoiding contact with personal items of infected people can help lower your chances of infection. If you do become infected, the most common treatment is an injection of long acting benzathine penicillin G. This treatment will cure the infection and prevent further damage but cannot fix the damage that has already been done. (CDC 2022)
