Scrotal masses are abnormalities in the bag of skin hanging behind the penis (scrotum). The scrotum contains the testicles and related structures that produce, store and transport sperm and male sex hormones. Scrotal masses might be an accumulation of fluids, the growth of abnormal tissue, or normal contents of the scrotum that have become swollen, inflamed or hardened. Scrotal masses need to be examined by a doctor, even if you're not in pain or having other symptoms.

Nipah Virus (NiV)

Nipah Virus (NiV) Nipah virus (NiV) was first discovered in 1999 following an outbreak of disease in pigs and people in Malaysia and Singapore. This outbreak resulted in nearly 300 human cases and more than 100 deaths, and caused substantial economic impact as more than 1 million pigs were killed to help control the outbreak. While there have been no other known outbreaks of NiV in Malaysia and Singapore since 1999, outbreaks have been recorded almost annually in some parts of Asia since then—primarily in Bangladesh and India. The virus has been shown to spread from person-to-person in these outbreaks, raising concerns about the potential for NiV to cause a global pandemic. NiV is a member of the family Paramyxoviridae, genus Henipavirus. It is a zoonotic virus, meaning that it initially spreads between animals and people. The animal host reservoir for NiV is the fruit bat (genus Pteropus), also known as the flying fox. Given that NiV is genetically related to Hendra virus, another
