Chlamydia, or more specifically a chlamydia infection, is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis. Most people who are infected have no symptoms. When symptoms do appear they may occur only several weeks after infection; the incubation period between exposure and being able to infect others is thought to be on the order of two to six weeks. Symptoms in women may include vaginal discharge or burning with urination. Symptoms in men may include discharge from the penis, burning with urination, or pain and swelling of one or both testicles. The infection can spread to the upper genital tract in women, causing pelvic inflammatory disease, which may result in future infertility or ectopic pregnancy.
Conjunctivitis, also known as pink eye, is inflammation of the outermost layer of the white part of the eye and the inner surface of the eyelid. It makes the eye appear pink or reddish. Pain, burning, scratchiness, or itchiness may occur. The affected eye may have increased tears or be "stuck shut" in the morning. Swelling of the white part of the eye may also occur. Itching is more common in cases due to allergies. Conjunctivitis can affect one or both eyes.
Blepharitis, sometimes known as "granulated eyelids," is one of the most common ocular conditions characterized by inflammation, scaling, reddening, and crusting of the eyelid. This condition may also cause swelling, burning, itching, or a grainy sensation when introducing foreign objects or substances to the eye. Although blepharitis by itself is not sight-threatening, it can lead to permanent alterations of the eyelid margin. The primary cause is bacteria and inflammation from congested meibomian oil glands at the base of each eyelash. Other conditions may give rise to blepharitis, whether they be infectious or noninfectious, including, but not limited to, bacterial infections or allergies.
Campylobacteriosis is among the most common infections caused by a bacteria in humans, often as a foodborne illness. It is caused by the Campylobacter bacterium, most commonly C. jejuni. It produces an inflammatory, sometimes bloody, diarrhea or dysentery syndrome, and usually cramps, fever and pain.
Swine influenza is an infection caused by any of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) refers to any strain of the influenza family of viruses that is endemic in pigs. As of 2009, identified SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3.
Brazilian purpuric fever (BPF) is an illness of children caused by the bacterium Haemophilus influenzae biogroup aegyptius which is ultimately fatal due to sepsis. BPF was first recognized in the São Paulo state of Brazil in 1984. At this time, young children between the ages of 3 months and 10 years were contracting a strange illness which was characterized by high fever and purpuric lesions on the body. These cases were all fatal, and originally thought to be due to meningitis. It was not until the autopsies were conducted that the cause of these deaths was confirmed to be infection by H. influenzae aegyptius. Although BPF was thought to be confined to Brazil, other cases occurred in Australia and the United States during 1984–1990.
Adenovirus infection is a contagious viral disease, caused by adenoviruses, commonly resulting in a respiratory tract infection. Typical symptoms range from those of a common cold, such as nasal congestion, coryza and cough, to difficulty breathing as in pneumonia. Other general symptoms include fever, fatigue, muscle aches, headache, abdominal pain and swollen neck glands. Onset is usually two to fourteen days after exposure to the virus. A mild eye infection may occur on its own, combined with a sore throat and fever, or as a more severe adenoviral keratoconjunctivitis with a painful red eye, intolerance to light and discharge. Very young children may just have an earache. Adenovirus infection can present as a gastroenteritis with vomiting, diarrhoea and abdominal pain, with or without respiratory symptoms. However, some people have no symptoms.
Neonatal conjunctivitis is a form of conjunctivitis which affects newborn babies following birth. It is typically due to neonatal bacterial infection, although it can also be non-infectious. Infectious neonatal conjunctivitis is typically contracted during vaginal delivery from exposure to bacteria from the birth canal, most commonly Neisseria gonorrhoeae or Chlamydia trachomatis.
Infectious bovine keratoconjunctivitis (IBK), also known as pinkeye, New Forest eye or blight, is a veterinary infection of cattle caused by Moraxella bovis, a Gram-negative, β-haemolytic, aerobic, rod-shaped bacterium. It is spread by direct contact or by flies serving as vectors. It is the most common ocular disease of cattle. IBK is similar to human pink eye and causes severe infection of the conjunctiva, edema, corneal opacity, and ulceration. This disease is highly contagious and occurs worldwide. Younger animals are more susceptible, but recovery with minimal damage is usual, if they are treated early.
The 2009 flu pandemic was a global outbreak of a new strain of influenza A virus subtype H1N1, first identified in April 2009, termed Pandemic H1N1/09 virus by the World Health Organization (WHO) and colloquially called swine flu. The outbreak was first observed in Mexico, and quickly spread globally. On 11 June 2009, the WHO declared the outbreak to be a pandemic. The overwhelming majority of patients experienced mild symptoms, but some persons were in higher risk groups, such as those with asthma, diabetes, obesity, heart disease, who were pregnant or had a weakened immune system. In the rare severe cases, around 3–5 days after symptoms manifest, the sufferer's condition declines quickly, often to the point of respiratory failure.
Acute Haemmorrhagic Conjunctivitis is the inflammation of the conjunctiva of sudden onset. It presents as a reddening of the eye due to the infection of the conjunctiva. The conjunctiva is the thin transparent tissue that covers the eye from the Corneal limbus to the lid margin. Many conditions can lead to the inflammation of the conjunctiva. They include allergies, bacterial infection, viral infection etc. A common form of the condition that occurs every rainy season is the seasonal conjunctivitis popularly referred to as "Apollo" by West Africans because the reports of its first epidemic in Accra coincided with the Apollo 11 Moon landing. Every year prior to the rainy season in the country, various health warnings are given to remind citizens of the condition.
Dengue fever is an important infectious disease in Pakistan with increasingly frequent epidemics. Despite the efforts of the Government of Pakistan, especially in Punjab, the high cost of prevention has limited the ability of Pakistan to control epidemics. In Pakistan, in the summer of 2011, more than 300 people died of Dengue fever. The prevalence of the disease was over 14,000. The outbreaks occurred mostly in the Lahore area, Punjab, Pakistan.
Acute hemorrhagic conjunctivitis (AHC) is a derivative of the highly contagious conjunctivitis virus, otherwise known as pink eye. Symptoms include excessively red, swollen eyes as well as subconjunctival hemorrhaging. Currently, there is no known treatment and patients are required to merely endure the symptoms while the virus runs its five- to seven-day course. While it was first identified in Ghana, the virus has now been seen in China, India, Egypt, Cuba, Singapore, Taiwan, Japan, Pakistan, Thailand, and the United States.
Ebola, also known as Ebola virus disease (EVD) and Ebola hemorrhagic fever (EHF), is a viral hemorrhagic fever in humans and other primates, caused by ebolaviruses. Symptoms typically start anywhere between two days and three weeks after infection. The first symptoms are usually fever, sore throat, muscle pain, and headaches. These are usually followed by vomiting, diarrhoea, rash and decreased liver and kidney function, at which point some people begin to bleed both internally and externally. It kills between 25% and 90% of those infected – about 50% on average. Death is often due to shock from fluid loss, and typically occurs between six and 16 days after the first symptoms appear. Early treatment of symptoms increases the survival rate considerably compared to late start. An Ebola vaccine was approved by the US FDA in December 2019.
There have been several outbreaks of Nipah virus in Kerala, some of which have been traced to fruit bats. The National Institute of Virology, Pune, confirmed the first case of Nipah virus in Kerala in May 2018.
The COVID-19 pandemic in Pakistan was a part of the ongoing pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached Pakistan on 26 February 2020, when two cases were recorded. On 18 March 2020, cases had been registered in all four provinces, the two autonomous territories, and Islamabad Capital Territory, and by 17 June, each district in Pakistan had recorded at least one confirmed case of COVID-19.
The Indian state governments have responded to the COVID-19 pandemic in India with various declarations of emergency, closure of institutions and public meeting places, and other restrictions intended to contain the spread of the virus. A comparative analysis on subnational responses in India finds that the response varied across the states, with varied levels of success, and that a successful pandemic response depended partly on the quality of health infrastructure but more significantly on factors such as local governance, community engagement, and decisive leadership.
Countries and territories in South Asia have been affected by the COVID-19 pandemic. The first South Asian country to report a confirmed case was Nepal, which documented its first case on 23 January 2020, in a man who had returned from Wuhan on 9 January. As of 2 July, at least one case of COVID-19 has been reported in every country in South Asia. Afghanistan, Bangladesh, Pakistan and Maldives have implemented lockdowns, Sri Lanka has responded with quarantine curfews while India and Nepal have declared a country-wide lockdown. Countries have also instituted various levels of restrictions on international travel, some countries have completely sealed off their land borders and grounded most international flights.
A Tablighi Jamaat religious congregation that took place in Lahore's Raiwind Markaz in early March 2020 was a COVID-19 super-spreader event with more than 539 confirmed cases linked to the event being reported across the country. Science and Technology Minister Fawad Chaudhry blamed the "stubbornness of the clergy" for the event having gone ahead despite the COVID-19 pandemic.
