It was the third time Mandela, known affectionately to South Africans by his clan name, Madiba, has been hospitalized since December. The unexpected late-night admission rang alarm bells for many. South Africa's first black president went into a hospital in Pretoria just before midnight.

Infections may do more than run you down, make you feel miserable and cause absences from work or school: A new study finds that having a long track record of infections may bite into your mental reserves as well. Scientists have long suspected that infections wreak havoc not just on the body but on the mind as well, and it doesn't seem to matter whether the infections are viral or bacterial, or what part of the body they affect. Having a medical history that includes more than the usual infections puts a patient at higher risk of stroke and vascular disease.

A Maryland transplant recipient has died of rabies after receiving an infected organ from a donor, the Centers for Disease Control and Prevention confirmed Friday. The CDC said that three other patients also received organs from the rabies-infected donor and were now receiving rabies shots. Transmission of rabies through donated organs is extremely rare. "The organ transplant occurred more than a year before the recipient developed symptoms and died of rabies," read a CDC press statement.

Fifteen people have now been infected infected with the new strain of coronavirus that appears to have originated in the Middle East, and nine have died. The most recent casualty was a 39-year-old man in Saudi Arabia who became ill on Feb. 24, was admitted to a hospital on Feb. 28 and died two days later. So far, there are no known links between the man and anyone else who had the virus, according to the World Health Organization . Scientists and public health officials have been scrambling to learn more about this coronavirus since its emergence last fall.

The U.S. Food and Drug Administration on Tuesday warned that the widely prescribed antibiotic azithromycin -- marketed as Zithromax and Zmax -- may cause potentially fatal changes in the heart rhythm of people who are taking medications to treat existing heart arrhythmia or who have a slower-than normal heart beat or magnesium or potassium deficiencies. Patients with a prolonged QT interval, a heart rhythm irregularity that is a risk factor for ventricular arrhythmias, also should avoid use of the antibiotic, the FDA warned . Azithromycin, one of the most commonly prescribed antibiotics, is used to treat bacterial infections such as ear infections in children, urinary infections, bronchitis, pneumonia and chlamydia, a sexually transmitted disease.

A newly identified virus tied to five deaths worldwide since April appears capable of transmission from one person to another, British health officials said Wednesday. The virus, part of a family called coronaviruses that range from the common cold to SARS, was found in a British resident who was apparently infected by a relative. It can cause fever, coughing and breathing problems. Until now, health officials had little evidence of whether the virus could be transmitted from person to person.

Though leafy greens accounted for the most U.S. food-related illnesses, poultry caused the most deaths, the U.S. Centers for Disease Control and Prevention said Tuesday. The Atlanta-based agency examined 4,589 food-related disease outbreaks from 1998 to 2008, the first comprehensive study of its kind by the agency. The CDC looked at outbreaks across 17 food categories and found that almost half of all outbreaks originated from leafy greens, which include lettuce and spinach.

Could "vaccine diplomacy" work on the Korean peninsula? The short answer is yes. North Korean leader Kim Jong Un, in a New Year's Day speech, called for reductions in international tension and an end to confrontation with South Korea, while raising the prospect of reunification between the North and South. Ultimately, science diplomacy could play an essential role in helping catalyze improved North-South relations in 2013, with joint programs for elimination of neglected diseases as a cornerstone.

Paging Dr. House: There a new tick-transmitted spirochete in town, and this wily relative of the organism that causes Lyme disease is probably sickening more than 4,300 Americans a year with relapsing fevers and flu-like symptoms, according to a new report. The good news: A round of common antibiotics appears capable of vanquishing the newly discovered threat. The organism, called Borrelia miyamotoi , was discovered in 1995 in Japan, but it was not until 2011 that disease hunters found and described evidence that it was making people sick in Central Russia.

A new study has found that an infusion of feces from a healthy person into an ailing patient's gut was significantly more effective than a traditional antibiotic treatment - raising hopes that the unconventional approach could one day help combat obesity, food allergies and a host of other maladies. The study, published online Wednesday by the New England Journal of Medicine, demonstrated that the fecal transplant cleared up a recurrent bacterial infection far more reliably than the routinely prescribed medication.
